Construction backlog down 5.4% in Q1
WASHINGTON — On May15,
Associated Builders and Contractors
released its Construction Backlog
Indicator (CBI) for the first quarter of
2012. CBI is a forward-looking
economic indicator that measures the
amount of construction work under
contract to be completed in the future.
CBI declined 5.4% from the previous
quarter, dipping from 7.8 months to
7.4 months but is slightly higher
compared to the first quarter of 2011.
“On the heels of a mixed bag of
national economic news, CBI declined
for the second quarter in a row,” said
ABC chief economist Anirban Basu.
“The nation’s nonresidential
construction activity will remain soft
during the summer months, with flat
to declining nonresidential
construction spending.
“The ongoing instability in the
nation’s nonresidential construction
industry appears to be related to the
period of economic weakness that
developed in the broader economy
last year, as well as to concerns
[about] recessionary forces in Europe,”
Basu said. “The result is that many
prospective construction projects
were cancelled or postponed.”
Regional highlights
• Compared to the first quarter of
2011, construction backlog is slightly
higher in every region, with the
exception of the Northeast.
• In the West, construction backlog
expanded by 0.46 months from the
fourth quarter of 2011 to the first
quarter of this year.
• The Middle States have the
shortest backlog at 6.34 months and
the South continues to register the
lengthiest backlog at 8.88 months.
Analysis
The South, which includes a
number of rapidly expanding,
commodity-rich states, continues to
produce the most new opportunities
for contractors. Although average
construction backlog in the South was
roughly flat during the past quarter,
backlog is up by seven-tenths of a
Construction material prices inch up 0.1% in April
I
n a sign of easing inflation pressure,
the nation’s construction materials
prices increased 0.1 percent in April,
according to the May 11 Producer
Price Index report by the U.S. Labor
Department. Construction materials
prices are up 2.5 percent compared to
the same time last year.
Nonresidential construction materials
prices were unchanged for the month
but are 2.4% higher than one year ago.
Prices for plumbing fixtures and fittings
decreased 0.7% for the month but are
up 2.5% compared to the same time
last year. Other materials, such as

Noritz marks 10th year in
North America with contractor promo
FOUNTAIN VALLEY, CALIF. — To
celebrate the 10th anniversary of its
entry into the U.S. tankless water
heating market, Noritz America
Corporation recently unveiled a 10month contractor appreciation
promotion designed to recognize and
reward members of its ongoing
PROCard Program, as
well as to attract
additional professional
installers to the group.
By submitting
warranty registrations
on Noritz products
installed between
March 1 and
December 31 of this
year, participating
contractors will earn chances to win
prizes in monthly and quarterly
drawings. All participants will also be
eligible for the grand prize drawing
in January 2013 when the winner
will receive a new Yamaha Rhino
700cc fuel-injected, side-by-side
month from one year ago. No other
region has generated an increase in
backlog that large.
Construction backlog expansion in
the Middle States continues to be
stifled, with sporadic gains in
industrial production during the past
year, too scattered to induce the next
wave of manufacturing-related
construction projects. Average
construction backlog in the
Northeast has fallen on a year-overyear basis. Last year’s soft patch,
including the economic weakness
associated with the debt ceiling issue,
appears to have impacted the
financial institution-rich Northeast
more than any other region.
utility vehicle, valued at $19,000.
Noritz will actively promote the
2012 PROCard Promotion through
trade-publication advertising,
promotional fliers and supply house
counter displays, articles in the
monthly PROCard Newsletter, and
postings on the company’s Facebook
and Twitter sites as
well as the PROCard
website. “The goal of
this promotion is not
just to celebrate our
company’s tenth year
in North America, but
also to express
appreciation to our
PROCard members
for their loyal and
enthusiastic support of our product
line over the past decade,” said Jay
Hassel, VP-marketing for Noritz
America.
The 2012 PROCard Promotion is
open to all program members in the
United States and Canada at
products and lumber posted small
increases in April and increases of about
2% over last year’s figures. Prices for
roofing and siding dropped 2.6% and
3.3% over April 2011.
“Recent news pertaining to the U.S.
nonresidential construction industry
has been somewhat disheartening of
late,” said Basu. “Still, at the very least,
contractors have been enjoying the
benefits of stable materials prices.”
Basu further explained that
materials prices are subject not only
to specific demand but to the whims
of equity and bond investors looking
to reduce exposure to other assets.
www.noritz.com/10-year-promo/. To
join PROCard, interested contractors
should visit procard.noritz.com or
call (866) 766-7489.
Each month, Noritz will draw five
entries from the pool of warranty
registrations for the previous 30 days,
awarding each contractor-winner a
prize valued at between $250 and
$1,750. Awards will include Noritz
NRC83-DVC tankless water heaters,
as well as a selection of power tools
and electronic equipment, such as
Apple iPod Touch music and video
players, DeWalt 18-Volt Cordless 4Tool Combo Kits, Kindle Fire
elec-tronic readers, Bose iPod Sound
Docks, and Sony PlayStation® 3
Systems.
In June, September and December,
Noritz will draw one additional
winner who will receive a Yamaha
TW200 Dual Purpose Dirt Bike or a
Yamaha Raptor 250 All Terrain
Vehicle, valued at $6,000 each. All
PROCard members who submitted
at least one warranty registration
over the previous 90 days, including
the monthly winners, will be eligible
for these quarterly drawings.

Construction industry trade groups
promote drug-, alcohol-free workplace
WASHINGTON — Five of the
nation’s largest construction trade
associations have teamed up to form
the Construction Coalition for a
Drug- and Alcohol-Free Workplace
(CCDAFW). The coalition’s mission
is to provide the construction
industry with the resources necessary
to implement drug- and alcohol-free
policies into their business practices.
CCDAFW has launched a
nationwide effort urging
construction-related firms and
organizations to sign an online
pledge signifying they will create and
maintain a workplace free from
substance abuse.
The CCDAFW is comprised of
Associated Builders and Contractors
(ABC), the Associated General
Contractors of America (AGC),
Construction Industry Round Table
(CIRT), Construction Users’
Roundtable (CURT) and Women
Construction Owners Executives
(WCOE).
“We are driving an industry toward
world-class safety,” said ABC
president and CEO Michael D.
Bellaman. “If we want to have an
industry that is world class in safety,
we have to start with a rock-solid
foundation that includes an
environment free of drugs and
substance abuse. This coalition is a
way to help companies build that
foundation so we can continue
toward our goal of eliminating all
fatalities on construction worksites.”

Nassau County N.Y. PHCC and Dellon
Sales Company get involved in education
BY RICHARD DI TOMA CONTRIBuTING WRITeR
I

believe in educating contractors in sound business
procedures. I also emphasize the delivery of excellence
to consumers. I am ecstatic whenever contractors who
listen and properly implement my theories and methods
improve their business results, increase their ability to
deliver excellence to consumers and lower their businessrelated stress levels.
My euphoria escalates when organizations like the
Nassau County PHCC and Dellon Sales Company, a
manufacturer’s representative, both located on Long
Island, N.Y., come together to help in the effort. This
commentary is dedicated as a thank you to those two
institutions and as an example of how to start improving
our noble industry.
Dellon Sales Company has graciously provided their
training facilities to the Nassau County PHCC so they
can offer educational programs to PHC contracting
businesses to help contractors improve their business
expertise.
My involvement started when Bobby Gramman, a
contractor friend with the Nassau County PHCC, asked
me to speak at an association event sponsored by Dellon
Sales Company on May 9, 2012. I had the honor of
speaking to over 50 PHC contracting businesses about
improving their business results and lowering their
business stress. Dellon provided their facilities and a
sumptuous BBQ meal. Attendees had the opportunity to
win great door prizes, and a contribution was presented to
Habitat for Humanity.
The Nassau County PHCC/Dellon Sales Company
alliance and the assistance I have offered to them, will
make a better tomorrow for everyone in that area,
including the consumers served by the PHC industry.
Dellon Sales Company
Dellon Sales Company is an award winning operation
staffed by a very talented and energized group of people
led by owner and CEO Scott Dellon. Scott is the fifth
generation of Dellons serving the plumbing industry, and
his son David has extended that string to a sixth
generation. Scott believes his staff is the reason Dellon
Sales Company is a unique enterprise, with the ability to
deliver superior quality service to their clientele.
Dellon Sales Company is dedicated to the
improvement of the industry through excellence and
education and has created the Dellon University to keep
clientele abreast of the latest technologies. I asked Scott
the following questions to understand his perspective on
this joint educational undertaking:
Why is Dellon Sales Company joining forces with the
Nassau County PHCC to sponsor events for PHC
contractors?
“Dellon Sales Company has always enjoyed working
closely with various organizations related to the plumbing,
heating and fire sprinkler industry. We enjoy developing
relationships with members of our industry. PHCC is an
excellent organization and actually adds value to its
members and helps make our industry better. We are a

member and try to support and help them out in any way
that we can.”
What educational programs does Dellon Sales
Company provide at your university?
“We have a classroom here that we call Dellon
University. It can accommodate over 50 people and
has operating displays and audio visual aids. We
provide training and certification classes on virtually
all the lines that we represent, including Baxi wall
hung boilers, Roth dual containment oil tanks, Anvil
Gruvlok and Blazemaster Fire protection. We teach
plumbers and service techs on Bradford White
residential and commercial water heaters. We even
host AIA and CEU courses for American Standard,
Elkay, Mr. Steam, InSinkErator and Eemax for
architects and engineers.
I am ecstatic whenever
contractors who listen and
properly implement my
theories and methods improve
their business results, increase
their ability to deliver
excellence to consumers and
lower their business-related
stress levels...

‘We also hold NKBA meetings here to review industry
trends and opportunities for their local chapter.”
Who are the people at Dellon Sales that are
responsible for your educational programs?
“Various members of the Dellon team are involved in
running Dellon University. Different Dellon teammates
do the scheduling, planning and training, depending on
the topic of the training session or the group or
organization involved in the course. I would say it’s a
team effort.
“Our marketing manager Brent Brake helps coordinate
the trade groups’ activities as well as handling and being
on the board of the NKBA. Spencer Bodner, Joe Knott
and John Delvecchio handle our heating department and
all activities that revolve around it. Jon Ross and Tony
Pennello handle everything that has to do with the
engineering community and the plumbing trade. Ken
Shwab specializes in Elkay and Mr. Steam. David Dellon
and I oversee everything that goes on in Dellon University
and help out wherever we can.”

PHCC is always promoting education and, when possible,
discounting to our members.”
What is the purpose of your meetings sponsored by
Dellon Sales Company?
“Basically to promote the PHCC. Dellon Sales is an
associate member of the PHCC and pays to participate in
our meetings.”
Ron Doughty, vice president of the Nassau County
PHCC, had a different
perspective on the
biggest problem in the
industry. He thinks
that the lack of
continuing education
is the major problem.
From a technical view,
he feels that
contractors who
received their licenses
years ago may not be

I also spoke with Joe Cornetta, president of the Nassau
County PHCC. Joe is the third generation of Cornetta
Bros. Inc., a plumbing and heating contracting firm
established in 1946. He says that the PHCC has exposed
him to countless ideas and opportunities. He regularly
attends conventions and trade shows, because the industry
is in a constant state of flux due to the fast pace of
technological advances. He says, “If you don’t learn, you
get left behind.”
I posed the following questions to Joe about the
association’s objectives regarding this alliance with Dellon
Sales Company:
What is the mission of the Nassau County PHCC?
“The PHCC is dedicated to the promotion,
advancement, education and training of the industry for
the protection of our environment and the health, safety
and comfort of society.”
From a technical view, Ron feels
that contractors who received their
licenses years ago may not be
keeping up with technological
advances and code changes.
What do you consider to be the biggest problem in the
PHC industry?
“There is a real problem with today’s generation getting
involved. It’s not just the PHCC. It’s all organizations.
Call any local volunteer fire department and ask if they
need help. The few who do join don’t really get involved.
Your fellow author Dan Foley hit the mark in Feb. 2012.
He asked, ‘What will a gym membership do for you if you
don’t participate?’ “
What is the solution to the problem?
“We are currently working with Nassau County to
achieve a county-wide license. One of the stipulations
would be that continuing education be required to renew
a plumbing license. The PHCC would head up training
and offer our members discounts or even include it in our
dues. This type of exposure will hopefully lead to more
members, some of whom may ‘get involved.’ Similar to
what you and I discussed regarding your seminars, the
Joe Cornetta,
President of Nassau
County NY PHCC
keeping up with technological advances and code changes.
As a local PHC inspector, he sees this problem first hand.
Regarding proper business protocols, Ron believes that
contractors don’t really know their true cost because they
lack business acumen. He says, “A good plumber is usually
a bad business person.”
Joe Cornetta and Ron Doughty both have valid points
about that which they believe is the problem. When
contractors don’t get involved they can’t keep up on
proper technical and business procedures.
Getting involved
The Nassau County PHCC and Dellon Sales Company
should be applauded for choosing to get involved by
becoming part of the solution rather than staying part of
the problem by doing nothing. Those of you reading this
would serve yourselves and the industry well by
emulating the efforts of these two great and caring
organizations.
Joe Cornetta is right! If you don’t get involved, nothing
gets done. Get involved; send a message in your area. Tell
PHC contractors, associations, wholesalers and
manufacturing representatives that you want them to do
their part to improve our industry by supporting
education in proper business protocols. With the right
education, it is possible to improve your business results
and lower your business stress levels. If you need my
assistance, give me a call at 845/639-5050. I am looking
forward to helping the Nassau PHCC and Dellon Sales
Company achieve their educational goals. I’d love to help
you with yours. l

U.S. strives to become “Land of the Lead free”
Lead free legislation is a game-changer
“C
onverting from standard
brass to lead free plumbing
components is kind of like
an old man who needs to ease into a
hot tub,” said Darrell Read, operations
manager at wholesaler F. W. Webb’s
Williston, Vt., branch, New England's
largest plumbing and heating, cooling
and industrial supplies distributor,
with more than 70 locations in New
England and New York. “Here, in a
state most immediately affected by
the legislation, we recognize the need
to make changes and to provide the
new lead free products quickly, but we
also recognized the need to be
deliberate about it,” added Read.
By now, contractor demand for lead
free plumbing components in
California and Vermont, the first two
states to pass their own lead free
plumbing laws, is an ongoing need
with no turning back. During the next
year and a half, wholesalers and
contractors in all other states will need
to comply. Read’s advice: “Ease your
way into it. Sell or install all of the
standard products now while you can
and, as inventory is reduced, replenish
supplies with the new lead free
technology.”
Last month Watts Water
Technologies conducted a random
survey of 16 wholesalers and
contractors in Vermont and California.
They found that wholesalers were
generally eager to talk about the
impact of lead free technology and
that their contractor customers, as a
Minnesota Master Plumber Eric Aune, president of Zimmerman, Minn.-based Aune
Plumbing, says that he’s gradually making preparations for the switch to lead free
plumbing components.
whole, were receptive to the change.
The key variable they found,
however, was the way manufacturers
responded to the need to retool their
products and how effectively they
introduced wholesalers to the new
products. Watts Water managers were
delighted to learn from wholesalers
and contractors that they (Watts
Water) handled the transition well.
There are many facets and some
challenges to the seismic shift to lead
free plumbing components. As a
leading producer of lead free products
and technology, the brands of Watts
Water have also made a commitment
to being an information leader as well.

Eric Aune also has a few opinions about the U.S. economy and our responsibility as
buying/consuming Americans. “We owe it to our own labor force and
manufacturers to buy American,” he said.

In the opinion of contractors
Minnesota Master Plumber Eric
Aune, president of Zimmerman,
Minn.-based Aune Plumbing, says that
he’s gradually making preparations for
the switch to lead free plumbing
components. “I’d like to be ahead of
the curve, not behind it,” said Aune.
“Typically, I’m not real fond of
federally-mandated changes, but this
one has consumer safety at the core,
so I know I’ll need to remind myself of
that occasionally,” added Aune. “A
concern of mine is product availability.
When lead free goes large scale, the
last thing I’ll want to hear when I go
to my supplier at Twin Cities
Winnelson is that lead free products
are unavailable. Knowing that Watts
made a proactive commitment to be
ahead of the curve and to have the
broadest line of lead free products on
the market makes a very important
statement to me.”
He’s also got a few opinions about
the U.S. economy and our
responsibility as buying/consuming
Americans. “We owe it to our own
labor force and manufacturers to buy
American,” he said. “The lead free
issue is one we’ll all have to deal with,
so, as we respond, we can at least help
by installing products made here in
the U.S.
One of Read’s contractor customers
in Vermont is Kerry White, service
manager for Vermont Mechanical
PLUMBING
based in Williston. “My best advice for
transitioning to lead free components
is to maintain stock and inventory of
the lead free ball valves and fittings for
heating and plumbing applications.
We chose to switch to lead free for
everything from the get-go. That way
there were no mistakes.”
“It’s impossible to be too well
prepared,” added White. “Invariably,
suppliers will be limited in their
ability to meet the demand for lead
free products; short supplies means
that both installers and wholesalers
will have issues. If you can, stock up
on essential components.”
It’s a done deal
In December 2010, politicians and
industry experts anticipated new
legislation that would make the “Land
of the Free” also the “Land of the Lead
free,” pending a single but very
important signature.
Of course, we now know that in
January 2011 President Obama signed
the “Reduction of Lead in Drinking
Water Act” (or Senate Bill S.3874)
which set a new, federal standard for
the level of permissible lead in
plumbing fixtures that carry water for
human consumption. The Land of the
Lead free now begins in just 18
months. By 2014, the allowable lead
content in products providing water
for human consumption will change
You should start your transition soon, and smartly. A good first move: Contact each
supplier to confirm that their products are already lead-free compliant.
engineers should be proactive. Don’t
wait too long to start the transition,
because delays may ultimately be
costly.
2. Team up with quality
manufacturers. The new law will
change both the material and
manufacturing process for bronze and
brass products used in potable water
systems. The change is comprehensive,
requiring that manufacturers have
ample R&D resources.
3. Protect your business: Fines and
lawsuits may be just around the

product that does not meet the new federal
standard will be illegal and cannot be sold or
installed for use with potable water.
from up to eight percent to not more
than a weighted average of 0.25
percent of wetted surfaces. The new
bill will align allowable lead levels in
all 50 states with the earlier adopted,
permissible lead levels in California,
Vermont and Maryland state
legislation.
“In our opinion, the legislation
appears sufficiently simple and
straightforward. However, if you are in
the business of installing, specifying,
distributing or manufacturing
products to comply with the
legislation, there is much more to it
than meets the eye,” said Stephanie
Ewing, director of strategic
partnerships, Watts Water
Technologies.
Act, partner, protect
With mandatory, U.S.-wide
compliance set for January 2014, it’s
now time to grapple with the
implications. Watts Water
recommends:
1. Distributors, contractors and
corner for those who don’t abide by
the law.
“Lead free is a game changer,” adds
Ewing. “Our customers in California,
Vermont and Maryland can attest to
the impact to their business. We do
believe that proper planning and
compliance will shape our success or
failure for years to come.”
After January 4, 2014, every
potable plumbing product that does
not meet the new federal standard will
be illegal and cannot be sold or
installed for use with potable water.
Period. States will be required to
implement the new lead free
requirements through state or local
plumbing codes, and some states may
also enforce the requirements through
consumer protection statutes or other
laws. Violators of the federal law may
be subject to monetary penalties,
government lawsuits or civil lawsuits
brought by concerned citizens.
Managing risk
Lead free changes the landscape for
your business and introduces risks;
from your competitors, from product
quality issues and possibly from legal
and regulatory action. Another facet of
the lead free movement is that
allowing your competitors to get
ahead of you means running the risk
of losing your customers and sales.
Invariably, some suppliers and
manufacturers will take shortcuts.
When this happens, product
deficiencies, failures and (Who
knows?) lead in lead free metal
formulations will only become
apparent after purchase and
installation. Good advice: Protect your
business. Work with reputable
suppliers and manufacturers. This will
ensure that the products you sell start
from the highest quality materials and
processes and are able to meet or
exceed lead free requirements.
Failure to plan is not an
option
You should start your transition
soon, and smartly. A good first move:
Contact each supplier to confirm that
their products are already lead-free
compliant; if not, determine whether
they have clear plans to transition to a
lead-free equivalent in time for your
business to keep pace with the
legislation.
In most cases, you’ll want to
identify and sell off low-volume
specialty or seasonal products first.
Transitioning to high-volume lead free
products will typically occur later in
the transition plan.
Watts Water has taken the
implications of the federal mandates
seriously. They’re focusing R&D
resources on the lead free conversion.
They have also broken ground on a

Selecting lead free materials is not
as simple a process as it would seem.
There are many options available to
manufacturers; each option has its
own set of limitations. When
complying with the lead free laws,
there are many variables to address
that cover multiple manufacturing
processes, while being mindful of
material suitability and product cost.
The primary options available for
materials are lead free brass and
bronze, stainless steel and plastics.
Each lead free technology has costs
beyond the basic raw material to

“Manufacturers have a
responsibility to deliver lead free
compliant products that meet
customers’ expectations for
performance and serviceability. With
the various material options that are
available to meet the requirements of
the lead free statutes, development of
a material strategy is critical to
maintain performance and deliver
value to the end user,” said Jeff
Scilingo, director of R&D engineering
for Watts Water Technologies.
How to get started?
For those impacted by the new
national lead free legislation, making
the transition to lead free products can
appear overwhelming at first.
“Partnering with a manufacturer who
understands the impact of the law and
has experience with the challenges of
a change of this size is important,” said
Bill Tracey, western regional manager
for Watts Water.
Ultimately the goal is to offer
products that provide safer, cleaner
water for families, communities and
the future.

Building on success with third generation

recision Plumbing Products
was founded in the early 1960s
as Tempera Valve Corporation.
At that time Tempera Valve Corp.
had developed and patented a
pressure balancing valve and a Bac-2Bac manifold, which was sold
directly to the plumbing market in
the Pacific Northwest. In 1968 a
Plumbing Code Official from
Washington State who had
developed and patented a piston
type Water Hammer Arrestor, a
"pressure drop" activated floor drain
Trap Primer, and a Distribution Unit,
enquired with the three shareholders
of Tempera Valve Corporation to see
if there was an interest in marketing
these items. All shareholders agreed
that these new products should be
added to the Tempera Valve
Corporation product line.
Perrott and the
beginning of PPP
Chuck Perrott was employed by
Tempera Valve Corporation as their
one and only salesman. It was his
suggestion that they rename the
company “Precision Plumbing
Products Inc.” in order to better
define the new line of products.
Chuck spent the next ten years
traveling first through the Pacific
Northwest, and then eventually
expanding east calling on Plumbing
Code Officials and engineers, slowly
introducing the Water Hammer
Arrestors and Trap Primers to their
various jurisdictions. A number of

facility.
independent plumbing
representatives became interested in
the products offered by Precision
Plumbing and signed contracts with
Mr. Perrott to help him in the
wholesale distribution and
specification of our specialty product
line.
The company began to grow and
in 1982 Chuck’s CPA presented an
opportunity to acquire the business
and pay back the shareholders that
had originally founded Tempera
Valve Corporation. It was important
to Chuck to give the shareholders a
return on their investment and thank
them for giving him his start. Chuck
was 65 when he decided to put his
house on the line to fund the buyout
and acquire Precision Plumbing
Products, Inc.
Chuck hired me in 1984. We
worked together to grow the
business over the years and in the fall
of 2003, I was given the opportunity
to present a business plan to the
Board of Directors of C.H. Perrott,
Inc. for the purpose of purchasing
control of Chuck’s company. I was
successful in a shareholder buyout
plan and in October 2003, I formed
the new parent company, J. L.
Industries, Inc. with five operating
divisions.
The second generation
Jack Vilendre has been with Precision Plumbing Product since 1984 and bought
the company in 2003. His daughter Alison Amundson has been with the company
for 10 years, starting as a marketing assistant and learning as she moved up.
In 1975, after spending three years
in the military and graduating from
Portland State University with a
degree in International Marketing,
Omark Industries Inc., a construction
fastening manufacturer in Portland,
Oregon, gave me the opportunity to
take an outside sales position. This
new opportunity moved my family
to Omaha, Neb. I successfully
worked as a manufacturer's
representative in the construction
PLUMBING
business for five years. Omark was
acquired by ITT Corporation in
1980 and offered me a position of
Product Line Manager for their
Construction Fastening operation in
Portland, Oregon. Putting my
international marketing education to
work, two years later we successfully
launched a European fastening
manufacturing and marketing
product line. I had gained a great
deal of manufacturing and marketing
experience from my time at Omark
Industries and ITT Corporation.
Then in 1984, Mr. Perrott asked me
to join him at Precision Plumbing
Products. I was to now prepare for a
new challenge, only this time it was
all about family.
Tom Amundson visits with an employee as she assembles PPP products.
Early marketing plans for
growth
I joined Precision Plumbing
Products (PPP) in October 1984.
The remainder of that year, Chuck
and I worked in the plant on my
product orientation and planning for
the following year. The company to
that point had been engaged
primarily with the annual ASA
&PHCC trade show. There was no
product advertising in any of the
trade journals and we had a very
limited catalog. After spending
several months looking at the
number of variations of products sold,
cataloging a broader product line
became my first priority. I hired a
photographer and we went to work
expanding our catalog. At the same
time I designed an ad program
featuring all of our products in full
color.
The new catalog added a much
larger product display. We then
expanded PPP’s trade show schedule,
which attracted a lot of attention for
Precision Plumbing Products and also
gave me the opportunity to
reorganize our sales force over the
following two years. When hiring
our sales representatives, I stressed
product specification and stepped up
the focus on the engineering
community. Educating the
plumbing contractors was important
in designing a needed sales pull
through incentive for wholesale
distribution. I wanted to see “PPP”
in the master spec, and the
contractor asking for us by name.
Branding our product line as “PPP”
was most instrumental in the
sustained growth of our business in
North America.
At the same time I was working on
the North American marketing plan
we were getting quite a number of
inquires to represent our product
line in Asia and the Middle East. I
had placed our catalogs with a
number of marketing groups
specializing in companies wanting to
expand their foreign sales activities.
Adding representation in key
markets has been a very interesting
process and yielded not only amazing
growth but lasting friendships.
During these early years at PPP, I
felt it was very important to become
closely associated with the plumbing
codes and standards organizations
that propel our industry forward. I
acted as an advocate to promote
public health and safety through the
adoption of various ASSE standards.
I attended many code meetings and
also supported the code officials by
attending their annual meetings,
purchase booth space and sponsoring
elements of their events. I spent a
number of years as a member of
various ASSE working groups
developing standards, and eventually
was asked to join the ASSE
Standards Committee. We continue
to serve as a manufacturing member
of this group. In 2005, the Oregon
Governor’s commission appointed
me as a member of the Oregon State
Plumbing Board, where I am
currently serving a second term.
Facility size and operation
J. L. Industries, Inc. is comprised of
five operating divisions:
• Precision Plumbing Products
(PPP)
• Northwest Automated
Machining (NAM)
• Cascade Precision Molding
(CPM)
• Precision Hydronic Products
(PHP)
• Precision Metal Brazing (PMB).
Our manufacturing facilities are all
located in Portland, Oregon and we
produce nearly all of the parts
necessary to support PPP and PHP at
our facility. We have experienced
steady growth and expansion since
1985, but with these tough
economic times we have been forced
to “tighten the belt”, but still remain
strong and optimistic.
The importance of
wholesale distribution
Our long-standing relationship
with our plumbing wholesalers has
been a key element to our success.
The importance that we have placed
on these relationships is key to the
success of the distribution of our
product line in North America. We
are not the company that would
pursue “Big Box” distribution
channels. Instead, our loyalty has
always been with our plumbing
wholesale distributors. Their staff
gets the job done when the licensed
plumbing contractor has questions
regarding the right product for the
application.
Because “PPP” is a highly
engineered product line, we need
sales expertise provided by our
distributors to insure the right
product gets to the job every time.
Our representatives have worked
hard to help brand the product line
so the plumbing contractors know to
ask for “PPP” when purchasing
specialty plumbing items over the
counter. I have developed a number
of incentive plans to improve the
wholesale profitability and therefore
improve the flow of product across
their shelves. In the long term, and
as my company transitions into the
next generation, our relationship
with the plumbing wholesaler will
remain a key part of our continued
success.
Branding the “PPP” logo/brand
goes hand in hand with product
recognition. But, I think we are best
known for consistency in regards to
the quality of our products. The

“What valve do you most often use

say, “PPP”. We hold many patents in
this field and Precision Plumbing

Like the man said: “You’re not
getting any younger”! The transition
was a decision my wife and I made
jointly to begin to wind down my
participation at J.L. Industries, and
look forward to spending more time
together traveling and spoiling the
grandkids.
I had been doing a lot of research
on succession planning and of course
there are many examples of success
and some significant examples how
not to proceed. Since I had family
members already working in the
company, and a very dedicated work
force, I was not in favor of selling the
business. A better plan, in my view,
was to pass it through to a third
generation. I told my advisors that
we needed to work on a plan that
will be embraced by the entire family.
It took some time to structure a plan
that made good business sense, but
also satisfied those family members
who would not be directly involved
in the business going forward.
After meeting first with those
family members who would not be
directly involved in the day to day
business, and gaining their
unanimous support, I was free to
move forward. Therefore I am
pleased to announce that 100% of J.
L. Industries, Inc. stock will pass
directly through to a third generation
of family members.
Tom and Alison Amundson will
take full control of business
operations and continue to operate J.
L. Industries, Inc. out of our Portland,
Ore., manufacturing facilities. Alison
(my daughter) has been a full-time
employee for 10 years, starting as my
marketing assistant, and interfacing
with our sales representative on a
number of levels. Currently she
operates my Heating & OEM
divisions. Alison performs all of the
customer service functions while
managing purchasing and inventory
control activities for both Precision
Hydronic Products and Precision
Metal Brazing. Over Alison’s term of
employment she has become very
familiar with the overall operations,
and recently joined the Board of
Directors.
Tom (my son-in-law) joined the
company two years ago as Product
Line Manager. Prior to taking the job,
Tom had obtained three under
graduate degrees from Portland State
University. Tom worked
independently in the financial service
industry for five years and during
that time showed me that he was a
man that could be successful and
perform well under very difficult
circumstances.
Tom started at Precision Plumbing
by working in my machining and
product assembly operations as his
initiation into the business. I felt it
was very important that he start in
the business the same way I had
from the ground up. After six
months in the plant handling a
variety of jobs he joined me in the
office. Tom started picking up
technical calls while performing
other product line management
duties. Tom is also a member of a
number of standing committees and
is Chairman of the Product Cost
Reduction Committee. Most
recently, I have assigned Tom the
responsibility of managing the JLI,
Inc. Purchasing and Inventory
Control Department. Over the next
few years both Alison and Tom will
be groomed to lead our family
enterprise providing Leslie and I a
stress-free retirement.
In conclusion, Leslie and I are very
comfortable in our decision to pass J.
L. Industries, Inc. through to our
third generation. This decision has
had a very positive effect on my
entire employee base — providing
them a sense of security in a very
difficult economic environment. We
also made a similar announcement to
our manufacturing representatives,
which were met with unqualified
support. Tom and Alison look
forward, with confidence, to the
challenges and opportunities that lay
ahead and I am reassured that the
company remains in good hands. l

Revisiting ‘Homes
of the Future’
Rainwater
system prompts
LEED Platinum
Certification
32
I
n 1933, the Tennessee Valley
Authority (TVA) constructed a
model community, Norris,
Tennessee, as part of the Norris Dam
project. The series of small homes
served as the archetype for modern
and efficient living in that time
period. Over the course of the last
two-and-a-half years, 50 University
of Tennessee-Knoxville students have
been reviving the spirit of the old
town by building the new Norris
House.
“The project began in fall of 2008
to commemorate the TVA’s 75th
anniversary and is a 21st century
reinterpretation of the original series
of Norris homes,” said research
specialist and UTK architectural
alumnus, Samuel Mortimer.
The Norris House is the largest
design/build project ever conducted
by UTK students. The home aspires
to become one of only seven
certified LEED Platinum homes in
Tennessee. To accomplish this rating,
many factors come together, lending
to the project’s resolved focus on
sustainability.
“As unique and ingenious as the
whole project is, the heart and soul is
the Brae rainwater collection system,”
said Scott Robinson, owner of Scott’s
Plumbing in Knoxville.
“About 80 percent of the roof’s
surface area is used to collect
Over the last two-and-a-half years, 50 University of Tennessee-Knoxville students
have been building the new Norris House, complete with a plumbing system,
reverse osmosis system, greywater distribution system and solar domestic hot
water system.
rainwater,” said Mortimer.
From the roof, the water goes
through a series of pre-filters before
entering an above- ground, 400gallon storage tank. When the “house
tank” reaches capacity, overflow runs
into a 200-gallon tank below the
garden. The garden tank is equipped
with a hand pump to supply water to
the landscape and a vegetable garden
sized to grow enough produce for
two people.
The average annual rainfall on
campus is 54 inches per year. At that
rate, and with the roof area that
feeds the catchment tanks, the
system collects nearly 21,000 gallons
annually. With water saving fixtures,
calculations show that, with two
inhabitants, annual water use for the
home is 16,500 gallons, well below
the harvesting system’s capability.
According to Robinson, the system
that was installed during the home’s
construction — technology supplied
by BRAE, — harvests more rainwater
than Norris House occupants
typically use. Scott’s Plumbing, with
the help of the UTK team, also
installed portions of the home’s
plumbing system, a domestic water
solar thermal panel and a greywater
distribution system. The way the
system is set up, rainfall usually
exceeds the use of stored rainwater
and simply flows out onto a terraced
spillway, watering the gardens.
The spillway is made up of five

containing hearty local plant species.
“Landscape architecture majors
helped design the overflow beds,”
said Mortimer. “They carefully
selected plant species that can not
only handle being inundated with
water but also thrive in a droughtlike condition.”
“It’s very important to keep the
greywater from entering the sterile
city water,” said Robinson. “The
students worked to shed light on the
safety of using a greywater
distribution system as well as a rain
collection system. The town of
Norris was rightfully concerned
about greywater entering the
landscape.”
Since the greywater system is
experimental, both the city of
Norris and the design team wanted
a fail-safe alternative so, with the
flip of a valve, the system can be
easily diverted to serve the city
sewer.
Norris House greywater is
collected from the bathroom sink,
shower and washing machine. It is
piped underground and enters the
landscape through a perforated
canister buried in a large bed of
mulch and soil. The bed is sized to
hold approximately 150 gallons of
greywater before saturating and is
also planted with native plants that
were selected based on anticipated
greywater volume.
“The UTK team worked closely
with the Tennessee Department of
Conservation and the Norris Water
Commission to ensure health and
safety,” said College of Architecture
and Design assistant professor Tricia
Stuth. “The city manager worked on
ordinance revisions that were
ultimately passed by the city council.
The building permit allows systems
to operate for one year, under the
oversight of the UTK team, and data
collected will be used to support
making the temporary permits
permanent.”
The 768-square-foot home will
provide verifiable technical data to
demonstrate the viability of
residential rainwater collection and
use. The project was initiated as an
entry into the EPA’s People
Prosperity and the Planet (P3)
competition, a national competition
that encourages students to propose
“solutions to real world challenges
involving the overall sustainability
of human society.”
The first of four phases was a
research and design period, funded
by a $10,000 grant from the EPA.
Ultimately, UTK’s team was chosen
as one of six winners from among
40 teams, and the EPA granted
$75,000 to the project.
In phase two, students began their
collaboration with Clayton Homes,
manufacturer of modular homes.
Together, they established goals,
targeting a LEED for Homes
Platinum rating. Some students
collaborated with Clayton Homes
during the design phase. Others
prepared the physical site in Norris.
Another team began work on
various components of the
building’s interior for later
installation. During the fall 2010
semester, phase three construction
began.
“The students always bring a fresh
perspective to things that we do
every day,” said Andy Hutsell,
Clayton Homes designer. “They’re
passionate about their work, and
they’ll be much better equipped
when they go out into the world
because of the Norris House
experience.”
Now, in the midst of the
“demonstration and evaluation”
phase, the college’s chair of the
Master of Landscape Architecture
program and his wife will live in the
home. Energy consumption,
temperature, relative humidity,
water use and water quality will be
measured. At the end of the
evaluation period, the home will be
up for sale; proceeds will be used as
seed money for the next project.
From the standing seam alloy roof
to the reclaimed oak flooring, the
home is a prime example of what
LEED construction should be. With
a super-tight, heavily insulated
building envelope, the structure
loses very little energy to the
outside world. Every square inch
that could be insulated, was
insulated. Foundation block cores
were filled with Perilite as the
building footprint started to take
shape. Inside the foundation walls,
two inches of rigid insulation was
used, and the foundation rim was
sprayed with Icynene.
“We decided to use advanced
framing techniques, which results in
a 17 percent reduction in lumber
and substantially more insulation,”
said Mortimer. The 24-inch stud
bays are filled with thick batting
insulation. On the outside of the
walls, one-inch rigid insulation curbs
any thermal bridging across the twoby-six studs. The ceiling rafter bays
and gable ends were also filled with
batting insulation, and sheets of
half-inch rigid insulation were hung
before the drywall was installed. The
outside of the building is clad with
Atlantic white cedar. Double-pane,
low-E coated, argon-filled windows

also limit energy transfer.
“We calculated the home’s heat
loss at 17,442 Btu,” said Mortimer,
“or 19.5 Btu per square foot. The
blower door test yielded .04 ACH,
the lowest score ever verified by our
green-rater.”
A four-by-eight foot Enerworks
solar-thermal panel on the roof
supplies hot water to an 80-gallon
tank in the home. A 1.5 gpm
electric instantaneous water heater
supplements the solar-heater water
when necessary.
Heating and cooling the home is
achieved through the use of a
multiple-head mini split system.
The building has one traditional
bedroom as the first zone, a “swing
space” that can be used as a second
bedroom and a kitchen. Each of the
three zones calls for a separate air
handler; all are connected to a single,
multi-zone condensing unit. As an
addition to the HVAC system, the
new Norris House has an energy
recovery ventilation (ERV) system
in the sealed crawlspace under the
building. Depending on the season,
the ERV either pre-cools or prewarms incoming fresh air.
Throughout the project, goals set
by the student team were
consistently met. “UTK has never
done anything like this before,
especially on this scale” said
Mortimer.
“The Norris House project was
real-life work experience that’s
invaluable to the students who’ve
been involved,” said Mary French, a
College of Engineering grad student.
“I’m really glad I had the opportunity
to participate.” l

Geo: Lessons learned (Part 1 of 2)
BY DAN FOLEY CONTRIBUTING WRITER
W

hen I started my company ten years ago, I
wanted to focus on radiant floor systems and
mechanical systems for large custom homes. By
and large, I have been successful in meeting that goal.
About 40% of my business by dollar volume is in the
custom home market, and the majority of my systems
feature some form of radiant heat.
Early on, when I received queries on geothermal heating
systems, also commonly called ground source heat pumps
or GSHPs, I would pass the lead on to fellow contractors
who were experienced in designing and installing these
systems. As more and more of my clients began requesting
geo systems, I had to rethink my business strategy. When
the federal tax credits went into effect, the requests grew
dramatically, and I had to make a decision; educate myself
on geo systems or get left behind.
About six years ago, I took the plunge. After attending
manufacturer training and certification classes, my
company did its first geothermal installation. We have
since installed multiple projects, everything from small
residential projects to an 80-ton, 19-system commercial
project and everything in between. We currently have six
geo projects in progress at various stages of completion. I
have made many missteps along the way and have taken
some lumps. I still have much to learn, but I will share my
experiences with you.
As I sat in my first geothermal class, one thought struck
me: While the equipment was new, and I had to learn
some of the terminology, these were basically hydronic
systems. The ground loop was the source, the heat
exchanger was the load, and the physics of energy transfer
through the piping and pump were the same as a hydronic
heating or cooling system. In studying the piping diagrams,
the lack of an air separator and expansion tank caught my
eye. When I asked about this, I was told these were not
needed in a geo system. Supposedly, the flexibility of the
HDPE loop field piping and the small temperature deltas
did not warrant the need for these devices. This made
absolutely no sense to me.
I have installed air separators and dirt separators (or
combi dirt/air separators) on all of our loop fields. I also
install expansion tanks and pressurize the systems. I treat
these as I would any other hydronic system. I have to say I
don’t understand the concept of the “push/pull” pump
stations with two pumps. I prefer to install one properly
sized pump that pumps away from the expansion tank and
point of no pressure change. Installed this way on a
pressurized system, it minimizes the chance of pump
cavitation.
As I have been called out to service systems not installed
by my company, a common condition is a “flat” system
where the loop field lost its pressure charge. Typically, the
compressor is off on high head pressure due to a lack of
flow in the loop field. In any system, there will be minute
leaks through valve packing, flanges, threaded joints, etc. It
does not take much for the system to lose its charge. This
condition also wreaks havoc on the loop pump. A loss of
When I started my
company ten years ago,
I wanted to focus on
radiant floor systems
and mechanical systems
for large custom homes.
charge can cause the inlet side of the pump to drop below
atmospheric pressure, which can cause pump cavitation.
When I see a stack of 26-99s or 0011s in the corner, I
know it is time to pipe in the expansion tank. A good
quality air separator is essential to remove the dissolved air
that will inevitably come out of solution. A pump cart
won’t do this. A dirt separator will also help eliminate the
sand and sediment that invariably finds its way into the
loop piping as it is being assembled.
I am very conservative when designing my loop fields. I
design around 85º EWT (entering water temperature) as I
do not want to be short. It is not easy or inexpensive to
correct an undersized loop field.
Last summer, I was called to look at an underperforming
geo system. They had also recently lost two compressors in
the system. When I surveyed the system in early June,
before the heat of summer, the loop field was running at
109 F. Compressors don’t last very long running at 109 F
condensing temperature. Capacity suffers dramatically as
well. This loop field was drastically undersized.
During my survey, I found out that the owner had
added an addition that included a wine cellar and
commercial refrigeration equipment. All the new
mechanical equipment was water cooled and tied into the
existing loop field, which had already been designed to the
edge of the envelope. I tried to explain that the loop field
was like an ATM machine, you cannot withdraw more
than what is in the account. This account was overdrawn!
Due to landscaping, hardscaping, stone walkways, stone
patio, a pool, heli-pad and outbuildings, fixing this
problem was nearly impossible without major demo and
excavation work. An air cooled water tower was added
temporarily to Band-Aid the system. I do not know how
this was permanently resolved, as I politely excused myself
from this one.
I realize drilling is expensive. In my market, we pay $15
– $18 a foot, depending on location and geology. It can be
more on small infill lots in town. Additional casing, if
required, can add to the cost. That is pocket change
compared to going back and trying to fix a short well field.
Be conservative in your design; it is cheap insurance.
Many of my projects have multiple systems. I have been
on multi-system jobs where each system had its own
pump station and loop field. Properly sized, there is
nothing wrong with this approach, but, in my opinion, it is

| FROM THE FIELD |
not an ideal design philosophy. The problem is that each
loop field must be designed for peak load. Peak load rarely
(or never) occurs in all zones at the same time, which
leads to a wasteful design.
I prefer to design around one loop field that is sized for
a diversified load. A typical system will have one variable
speed loop pump that operates off an integral delta P
control or a 0 – 10v signal from a BMS (building
management system). Each heat pump will have a
motorized valve at the condenser inlet. As systems come
on line or cycle off, the variable speed loop pump will
ramp up or down accordingly. I will install a standby pump
that will automatically come online in the event of a
primary pump failure. It will also automatically rotate for
even wear. With this system, each heat pump “sees” the
entire loop field, which helps manage peak loads easily.
Most of our early projects featured fusion-welded
HDPE loop field piping. The last four or five projects we
have done have featured the Rehau Rau-Geo system. I
really like several features of this system.
1. I like the heavy duty PEX pipe. It is tougher than
HPDE and handles the jobsite abuse inevitable when
pulling loops.
2. I like the one continuous loop with no joints at the
bottom of the well.
3. I like the fact that all loops tie in to a manifold,
which allows for flow measurement and balancing of each
loop. It also allows for isolation of individual loops in the
rare event that one is hit, allowing for at least partial
system capacity.
4. I like the four-pipe system (two loops per borehole),
which increases the heat transfer capability.
Properly designed, installed and maintained, either
system will work fine. I just wanted to share my
experience with this relatively new product.
We typically run the loops back to a vault as shown in
photo # ( ). We then run a large dimension PEX back into
a basement mechanical room. This line is typically 2”, 2
1/2” or 3”, depending on flow requirement. This setup
minimizes the wall penetrations required and keeps the
mechanical room piping neat and tidy.
It is imperative to properly seal these wall penetrations. I
have seen too many geo systems where the leaders were
stuck through the foundation wall with some hydraulic
cement slapped around the pipe. Invariably, the wall is
stained by water leaks, and mud and sediment is puddled
on the floor below the penetration.
I prefer to either core drill or sleeve the foundation and
seal around the pipe with properly sized Link-Seal. This
will ensure a watertight seal. If you do use sleeves, be sure
to order the sleeves with the
ring around the middle,
which seals against leakage
around the outside of the
sleeve. I have seen jobs
where the well intentioned
installer used schedule 40
PVC for the sleeves and
properly Link-Sealed the
pipe. The problem occurred
when the concrete shrunk
away from the PVC and the
leak path was around the
sleeve. After backfilling, it is
very difficult to fix these
leaks. Spend a little time up
front and save yourself from
headaches and angry clients
down the road.
Geothermal systems are a
fast growing market niche in
my company. Stay with me
as I cover more of our design
and installation details in
next month’s column. l

TANKLESS REPORT
Tankless water heating catching second wind
I
n the wake of the most severe economic downturn since
the 1930s, the tankless water heater industry struggled
along with most other manufacturers as potential
customers retreated from purchases of products they saw
as “boutique” items. However, with more awareness of
rising energy costs and an increasing “green” attitude
among consumers, tankless technology has begun to
rebound as its efficiency and convenience is better
understood. Commercial buyers also favor tankless water
heating because of its obvious economy. ;

COMPANY HISTORY: A. O. Smith produced its first residential
water heater in 1939, establishing a tradition of innovation that
continues to this day. In 1953, A. O. Smith shipped its first
commercial water heater equipped with a “glass-lined” tank,
which remains the industry standard for protecting steel from
the corrosive effects of water.
In 2004, A. O. Smith reaffirmed its mastery of glass lining
technology by introducing patented Blue Diamond™ glass
coating on its best Conservationist® residential water heaters.
Blue Diamond provides the ultimate protection, with more than
twice the corrosion resistance compared to industry-standard
glass lining.
Company News: Recently, launching a new era in high
efficient products, A. O. Smith introduced a comprehensive line
of innovative new products, including hybrid gas, hybrid electric
and solar technologies.
A. O. Smith is now including a remote controller and/or
power cord with each tankless purchase. Indoor residential
tankless units will come with a remote controller and power
cord. Due to varying installation regulations from state to state,
outdoor residential tankless units will come with a remote
Just part of the A. O. Smith family of tankless water heaters.
controller only.
The remote controller will make installation and maintenance
easier for the contractor and homeowner alike by providing
access to information that could previously only be gathered by
removing the front panel of the heater. This includes the ability
to adjust the water temperature and view diagnostic data such as
incoming water temperature, flow rate, error code history and
total amount of Btu-run through the unit. Finally, this addition
allows the contractor to leave an avenue for end users to interact
with their appliance, giving the homeowner a level of control
they have never had before.
Tankless forecast: Previously, indoor tankless units arrived on
the jobsite with only positive and negative leads. The inclusion of
the power cord, which includes wire nuts and clamps, will
decrease the amount of time preparing for installation, with the
end result of more profit for the contractor.
The tankless industry has experienced phenomenal growth in
the past few years. However, for 2012, the elimination of the
federal tax credit has had a significant impact on the tankless
market, which has experienced roughly a 10 percent contraction
compared to 2011 figures year to date. We see this impact
continuing throughout 2012 unless other federal incentives are
implemented.
Assistance to contractors: A. O. Smith recently announced the
opening of its West Coast Training Center in Irvine, Calif. The
center is now offering training courses on the entire A. O. Smith
product line, including both high efficiency product family and
high efficiency tankless gas water heaters. Plumbing contractors
and wholesalers will be able to participate in hands-on training
courses catered to three skill levels: basic training, technical
trouble shooting and certified installer.
The new, 6,230-square-foot facility also houses an impressive
showroom featuring A. O. Smith’s entire high efficiency product
family on display. This state-of-the art facility will serve as a
model for future A. O. Smith training efforts.
Tankless FAQ: What are the special conditions that must be
taken into consideration when installing a tankless model? There
are two key points to consider for tankless installations. First, due
to the higher Btu input, tankless models require at least a ¾” gas
line to the unit. Most homes utilize a ½” gas line to the water
heater, so, in replacement applications particularly, the
homeowner will most likely need to upgrade to a larger gas line,
which is a major expense in
replacement applications.
Non-condensing tankless models
require stainless steel vent material
and cannot use the exiting B-vent
commonly used with most
conventional tank-type water heaters.
Stainless venting can be expensive,
although tankless models can be
vented horizontally through an
outside wall, which can help offset
the venting cost. Condensing
tankless models can use PVC
venting, which is less expensive than
stainless steel venting. In warmer
climates, tankless models can be
installed outdoors, eliminating the
need for venting altogether.
Biggest positive influence: The launch of the A. O. Smith
Warranty Check app made the company the first manufacturer
in the water heating industry to create an application of this kind.
Designed specifically for contractors and plumbers, the free app
allows plumbing professionals to easily check water heaters in
the field for warranty information and product details on both
residential and commercial products.
Since its launch, the Warranty Check app has had more than
2,300 downloads, with an average weekly growth of 13 percent.
Contractors have used it to check the warranties on more than
10,000 water heaters.
In addition to the new facility, A. O. Smith continues to offer
training workshops across the country. To register for a workshop

water pipe. The pressure relief valves supplied from AHI, however,
can work on either the incoming or the output water side.
Biggest positive influence: On tankless sales — new construction.
More engineering firms that specify for new construction jobs are
making inquiries. With improving economic conditions, some of the
construction projects that were on hold are now gradually being
restarted.

has experienced market growth. Currently, tankless water heaters
account for about 5% of the total market. Based on recent data
with green operational trends becoming more prevalent, we believe
this will include an increased adoption of tankless water heaters
among consumers. The biggest sources of growth in 2012 are
commercial, new home construction and high-end replacement
with recirculation.
Tankless FAQ: Why does Rinnai use polypropylene tubing instead
of PVC or CPVC pipe for exhaust venting its condensing tankless
water heaters?
Polypropylene (PP) is superior to PVC pipe for exhaust venting
because it has a maximum temperature rating of 248°F compared to
156°F for PVC and 194°F for CPVC. Unlike PVC and CPVC, PP has
been specifically engineered and certified to be used with condensing
tankless water heaters and other condensing appliances. ;

Tankless FAQ: Why do the majority of brands still vent with
costly stainless steel? When Quietside first came to market with
tankless several years ago we chose to offer only PVC-vented
options. Each unit is condensing and, therefore, more energy
efficient. PVC venting cuts costs in half, compared to venting
with stainless.

COMPANY HISTORY: Established in 2002, Noritz America is the
U.S. arm of the Japan-based Noritz Group, the largest producer of
tankless water heaters in the world. The Noritz Group began
producing water heaters in 1951 and tankless water heaters in 1966.
In 1981, Noritz developed the first electronically controlled tankless
water heater, which is the precursor to today’s advanced tankless
technology.
Company News: Condensing technology: The tankless market is
continuing the trend towards higher-efficiency, PVC-vented,
condensing water heaters, with the momentum carrying through
2012 and beyond. Noritz launched its new website on May 18, 2012.
The new site offers quick and easy access to essential information on
Noritz products and services. One of Noritz’ most critical objectives
is to help make its local PROCard program the local experts on
tankless technology for home and business applications with a
technical support website and an in-house call center.
New residential products: To meet the growing demand for
condensing water heaters, Noritz America completed the launch of
two additional condensing units late in 2011 to round out its full line
of residential condensing models.
Lower emissions: Both of the new condensing models feature a
high-efficiency, low-NOx Eco-Burner™ with a nitrogen-oxide
emissions level that is within 20 ppm and complies with the new
South Coast Air Quality Management District (SCAQMD)
regulations that went into effect on January , 2012.
Assistance to contractors: Noritz continues to focus on
communicating the message through comprehensive, tradeeducation programs, and has added more courses to the Noritz
University (NRU) catalog to meet contractor needs. Trainings are
held at branch offices and off-site locations. To register for a program,
contractors should visit noritz.com/professionals/
support/monthly_training/.
Tankless forecast: Every home in America has a water heater of
some sort, so the repair and replacement market will always be a
strong influence for growth at Noritz America. Alternatively, Noritz
is also seeing a huge increase in interest and business in the
commercial channel.
In most situations, increasing to 3/4" line will provide enough Btu/h,
and the gas meter also needs to be upsized to meet the whole home’s
demand. Consult with your plumber.
What is a Condensing tankless water heater?
Condensation is created inside Navien’s condensing heat exchanger
(secondary heat exchanger) from the incoming cold water, cooling
the hot gases inside the unit, recovering heat that normally would go
up the flue, making the process highly efficient and economical.
Navien Tankless Condensing technology is ideal for all
categories of the market, with several key features geared
toward repair and replace. Navien America was the
first tankless manufacturer to offer PVC vented units,
so installers can replace a tank water heater with a
Navien unit at a lower cost than a non-condensing
tankless water heater. PVC allows 0" clearance to
combustibles — perfect for long runs of vent at an
affordable cost. Navien’s Ready Link® System is the best
alternative for large volumes of hot water. With its easy
venting and installation, unlimited Navien Water Heaters can
be set up as one system and sudden hot-water cutoffs can be avoided.
Other features include:
• Abundant Hot Water Supply: 16 units can be linked as one group
within the system and several groups can be linked-up into one
system.
• Energy Saving: industry's most efficient multi-unit system with
an exceptional 98% efficiency.
• Easy Wiring Connection: simple wiring link without complicated
communication cables and controllers.
• Easy Ventilating: built in APS for longer vent pipe.
• Low Maintenance Cost: even if one unit of the system fails, the
rest will operate without any problems.
• Full Modulation System: units activate individually as the
demand for hot water increases. ;
Tankless FAQ: How do I vent tankless water-heaters?
For conventional models with efficiencies in the mid-80s, Category
III stainless steel venting is required. (Note: Existing B-Vent from
tank-type heaters cannot be reused.) For condensing models with
efficiencies in the mid-90s, solid-core Schedule 40 PVC pipe can be
used to vent.
What maintenance is recommended for tankless water heaters?
The filter, located on the cold-water inlet fitting, should be
checked for debris about once a year. The front cover, fan and
venting should be checked for dust and debris. Depending on water
quality, a heat exchanger flush may be necessary as well.
What should I do to treat hard water?
There are several technologies used to treat hard water, either by
changing its chemical nature or by removing scale-producing ions.
Noritz offers two such scale treatment devices: the H2Flow and
Scale Shield. A detailed flush procedure may be found at
noritz.com/u/descale_procedure.pdf.
How do I flush the heat exchanger?
Flushing or de-scaling is part of the
regular maintenance of a Noritz heater.
It involves circulating a solution of pure
vinegar or diluted CLR through the
heat exchanger, using a submersible
pump. You will need the following
equipment to conduct a de-scale:
bucket; submersible pump; isolator
valve kit (installed on heater); water line
connections (the isolator valves have
3/4" hose thread connections on their
flush ports) and de-scaling solution
(vinegar, dilute CLR, dilute lime-away).
For more information, consult the
“FAQ” section at support.noritz.com/. ;
The NRC83-DV, an indoor model with
a two-pipe direct vent system, uses
condensing technology to achieve an
Energy Factor of 0.92 or 0.94,
depending on the fuel type. It can be
vented with 3" or 4" Schedule 40 and 80 PVC or CPVC pipe, which
is less expensive and quicker to install than the Category III stainless
steel that must be used on conventional tankless water heaters.

COMPANY HISTORY: Founded in
Emeryville, Calif., in 1925 as Pacific
Galvanizing Company by brothers Richard and
Donald Rheem, the company made steel drums and other metal
products, and later narrowed its production to heating, cooling and
water heating solutions. Rheem began full-scale manufacturing of
water heaters, boilers and tanks in 1930; its water heating production
was significantly boosted in 1960 when it acquired the technology of
Norwegian water heater inventor Edwin Ruud. Today, the company’s
water heating product portfolio includes residential and commercial
tank, tankless, point-of-use electric tankless, solar and hybrid heat
pump water heaters, swimming pool heaters and commercial boilers.
Rheem is headquartered in Atlanta and its Water Heating division is
based in Montgomery, Ala.
Company News: In early 2011, Rheem invested more in
technology, innovation and product development over the past three
years than at any other point in the company’s history. Late in the
year Rheem introduced its Ultra Low NOx gas tankless water heaters
throughout the United States. In January 2012, Rheem debuted the
first-of-its-kind H2AC™ rooftop unit with eSync™ integration
technology for full-service restaurants.
Assistance to contractors: Some measures are offering new training
opportunities, supporting natural gas utility rebate programs, arming
contractors with resources to quickly develop marketing collateral and
streamlining our shipping program to better accommodate large orders.
Rheem has revamped its popular tankless training so that it focuses on
providing hands-on trouble-shooting and servicing. Rheem has
developed a variety of attractive vent termination kits that match the
upscale aesthetics featured on higher-end homes.
Tankless forecast: Greater awareness from homeowners about
tankless water heaters is helping the
industry at large. Today’s marketplace still
shows much greater demand coming
from replacement scenarios. With the
introduction of gas utility rebate
programs — and greater education on
the energy-specific benefits of tankless
water heaters from manufacturers —
Americans are becoming more aware
of the potential savings and benefits of
upgrading their water heaters to
tankless units. ;
The Prestige™ Series condensing
tankless water heater operates at 94
% thermal efficiency and features an
industry-best minimum flow rate of .26 gpm
and a minimum activation flow rate of .40 gpm.This unit
complies with SCAQMD.

COMPANY HISTORY: Grand Hall is an
international company that has served as a
leading manufacturer of innovative gas
appliances and components for more than 30
years. In 1985, the Eternal manufacturer
opened the U.S. office in Dallas, Texas. Today,
the 200,000 sq. ft. distribution facility built in
2003 utilizes state-of-the-art technology to
enhance operations. In 2006, Grand Hall
launched the first Eternal hybrid water heater in the U.S., released
the third generation of the series in 2010, and introduced the

throughout the U.S. that provide detailed instructions on the
installation process, and a 15 year residential/5 year commercial no
leak warranty, 24/7 technical support, and a network of distributors
with replacement parts.
Tankless forecast: The water heating industry has been stagnant
for years but is about to change with the DOE’s final rule for the
2015 minimum efficiency levels for all gas fired water heaters sold
in the U.S. The new standard could lead to a price increase on
standard tanks, close the gap with on-demand water heaters and
boost the on-demand market as consumers look for more efficient
water heaters. The repair and replace segment of the market is
growing due to the weak economy; with a lot of buildings and
homes having deferred maintenance and old equipment
Tankless FAQ: What about venting and piping? The Eternal can
be power vented or direct vented with 2" or 3" SCH 40 PVC. It
has a standard top connection on the unit which reduces
soldering time. ;

COMPANY HISTORY: Chronomite began in 1966 providing hot
water for point-of-use commercial and industrial applications.
At only the size of a dictionary, Chronomite tankless water
heaters use electricity to supply hot water on demand to
remote locations. After developing Omni Flow Controls in
1982, the company proved that water flow rate could be
reduced while still producing a pressure-compensated flow rate.
In 1992, Chronomite Laboratories Inc. patented the first
microprocessor controlled tankless water heater to provide
unlimited hot water simultaneously to multiple lavatories with
one heater. Utilizing state of the art technology, the
microprocessor reduces hot water delivery time, is 99% energy
efficient, and meets user demands for a cost-saving, quickreturn product.
Company News: An
all-new Web site at
www.Chronomite.com
that now features an
online configurator to
determine the precise
model that's right for the
job. The site also includes
more educational and
product resources,
including step-by-step instructions on how to install. Updated spec
sheets, downloads, comparison
charts, and online manuals make
finding information more userfriendly.
Tankless forecast: The current
or conventional infrastructure in
place for energy, water, and
utilities is being reevaluated to
protect our precious resources,
and the alternative has the
potential to be costly. Now, more
than ever, there is a demand for
eco-friendly alternatives. But also
because of the economy,
companies must provide
solutions that are immediately
accessible—low-cost alternatives
that produce quick results in
efficiency and fast payback for
utilities.
Assistance to contractors:
Chronomite has two warehouses
one in California and the other
in Georgia; along with a vast
network of
representatives/distributors to
assist the contractor with
availability and accessibility to
our products. Our website has
been designed with state-of the
art literature that can facilitate
with specification, product
determination, submittals and
installation sheets to aid in
selecting the desired product for
the application. Contractors
know we offer a quality product,
every unit is tested at the factory
prior to shipping, this results in
fewer call backs and that in turn
translates into more profit.
Tankless FAQ: If not gas, oil, or
propane, how does the Chronomite
tankless heater operate?
TANKLESS REPORT
It requires only a cold water line and
electrical hookup – no need for costly
piping/valving associated with
conventional tank heaters. The element
assembly houses a series of ingeniously designed coils that instantly
heat water as it flows through the vessel. A unique power switch
automatically applies electrical current to the coils when hot water is
requested. The electrical current is not applied when water is not in
use. The microprocessor can be preset at the factory to maintain a
constant output temperature, even at varying flow rates of the unit.
Will a Chronomite Tankless water heater supply my whole house?
A single Chronomite Tankless Water Heaters are designed for a
point-of-use commercial and retail applications, or in remote locations
which require warm water on-demand (i.e. outdoor pool showers,
restaurant service sinks, etc.) However, you can supply hot water to an
entire house with a Chronomite Parallel Kit. The parallel kit features
two Instant-Flow Micro heaters connected together to produce a
greater flow rate at 99% energy efficiency. The parallel kit easily
accommodates or retrofits in instances where higher volume (gpm) of
water is required, which requires higher amperage. Each heater uses a
digital microprocessor for temperature control and provides unlimited
hot water with no need for a mixing valve. Meets applicable building
codes including ADA, UL, IAPMO, UPC.
What would you say is the biggest positive influence (as far as
growth) for your company in 2012? (Repair & replace, new
construction, commercial, solar hot water, etc.): As the economy
begins to strengthen we look to new construction along with
repair/replace work to remain a strong source of sales. A tankless unit
is used to bring hot water to a remote location saving in time and
resources and this provides an opportunity to supply a more efficient
and greener product in a retrofit situation. We are also looking to
develop new products as the need arises to meet demand. ;

National employment mobility
guarantees long-term rental swing
BY MORRIE BESCHLOSS CONTRIBUTING WRITER
A
lthough a case has already been made for
homeowning stability at near current price levels, as
long as minimal mortgage rates exist and credit is
not harder to come by, a longer term prognosis would point
to the dominance of renting, at least for the next few years.
What has previously not been emphasized is the
extreme mobility of America’s huge and active 140-million
strong employment force. Whereas Americans have been
traditionally more mobile than other nations if better
opportunities exist in other parts of the country,
the current major hesitancy has been the
ability to shed their homestead to provide the

period.
liquidity to re-establish themselves elsewhere. This had not
posed a problem in the past 25 years, as home prices and
sizzling demand were not negative factors in flipping their
existing residences for relocation to new areas of
opportunity.
Even if economic conditions exceed current projections
up to 2020, the combination of demand exceeding supply,
resulting in ever-higher real estate prices, will likely not be
replicated in the current generation, spanning a 25-year
period. The stark reality, at a time when income-making
opportunities are increasingly difficult to find in the
proverbial backyard, is that the "employment factor" will
provide an overwhelming undertow to the tens of millions
wishing to keep their "job fulfillment" options open,
wherever they can be found within the confines of these
United States.
Anecdotal surveys have disclosed that this concern with
relocation is top-heavy for those rejecting the temptations
of long-term mortgages and financial risk in an economic
climate displaying little long-term hope for the price
improvement of a home-owning asset.
Since the post-World War II years, the home has been
the rock-solid asset centerpiece for the vast majority of
America’s wage earners. The nightmarish swing from asset
to liability since 2008’s Great Recession start has been a
traumatic blow from which few, if any, see any recovery
within their lifetimes.
Weighing the pros and cons of economic factors due to
emerge in the years to come (inflationary high interest
rates and tightening credit), it’s a safe call to predict that
rentals in major metropolitan areas and suburbs, as well as
in most outlying sectors, will become a permanent fact of
life.
More minimum wage legislation runs counter
to badly-needed employment opportunities
While President Barack Obama rails about millionaire
and billionaire tax surcharges and a minimum federal tax of
30% on all those with incomes over a million dollars (the
Buffett rule), the constant push for higher minimum wages
continues to boil at many state levels while still percolating
in the Oval Office, ready to spring on Congress when least
expected.
What proves the “Buffett rule” to be pure gimmickry is
that, if perfected, it would hardly collect $45 billion over a
decade but holds the “super-rich” up to scorn as greedy,
money-grubbing narcissists. Buffett, the nation’s
unchallenged super-investor, has lent himself to this
charade by charging that he pays a lower percentage of
federal tax than his secretary does, whose annual salary is in
the $75,000 range.
On the other end of the income spectrum, the jobrestraining incubus of minimum federal wage has
prohibited the hiring of tens of thousands of teenagers and
others in the growing unemployment sector. Many of them
would be readily employed by thousands of small
companies not ready to comply with the federal minimum
wage of $7.25 per hour.
A growing number of states have raised that bar ever
higher, even during the Great Recession. While Washington
State leads that parade with a $9.04 minimum,
Massachusetts is ready to approve a mandate of $10 an
hour, with Illinois right behind. Many job openings would
be available at competitive hiring rates for fast food
purveyors, where tips and other types of commissions
could be made available to those hired. Such positions are
going begging for those unemployed who comprise a
preponderant amount of job seekers, both percentage-wise
and numerically.
In the irrational world of current federal government
manipulation of wage levels, the major harm being
committed is to those who would prefer any job in
preference to the extension of the government dole of
unemployment compensation.
What the White House and Washington, D.C. fail to
understand is that “gainful employment” continues to be
the overriding problem of America’s shifting economy.
What the so-called progressives don’t want to face is that
increased minimum wages are the wrong way to go in a

languishing economy with maximum unemployment. The
current attitude displayed by union-driven state legislators
is that the already overburdened unemployment rolls are a
direct result of not allowing the marketplace to work at a
time when a waiver from minimum wages, not an
escalation, is needed.
Strong vs. weak dollar arguments often based
on false premise
52
Back in the “good old days,” those rooting for a strong
dollar (a consistent position of U.S. Treasury Secretaries)
believed that a powerful greenback signaled a strong U.S.
economy. The weak dollar camp, however, (hoping for
cheap dollars to ship their goods abroad and enhance
incoming tourism) perceived a distinct advantage in a soft
national economy. But like the currency in general, and all
aspects of life in particular, relative currency values are
getting more complicated.
More often than not, the long-term value of the
greenback is a reflection of its relationship to a basket of
major world currencies, such as the yen, pound, euro and
Chinese yuan. The dollar, the most widely used currency in
international trade, has constantly been in competition
with the relative strength of these leading world monetary
standard bearers.
With the lightning speed of economic globalization,
these hidebound historical scenarios are now in a constant
state of flux. The dollar reached maximum strength in the
early 1980s, when double digit interest rates for the
popular 10-year note enticed record influx from all over
the world. This was true as the monetary world saw
investment in U.S. debt as a no-brainer, providing
maximum security, combined with a heretofore unavailable
double digit yield. The fact that the U.S. was experiencing
runaway inflation did not discourage global investors, who
continued to view America as the ultimate pillar of
investment safety. Also, the U.S. debt had barely reached $1
trillion.
The relatively weaker dollar today is primarily a function
of historically minuscule interest rates generated by the U.S.
Treasury’s yield curve, despite a national debt that has
multiplied 15 times in the past 35 years. As was true during
America’s hyper-inflationary binge, the nation’s record
deficit spending and debt accumulation seems to be
overshadowed by the continued vote of confidence that
the bulk of the world’s money retainers exhort toward U.S.
domestic repayment and on-time interest payments.
With globally traded commodities such as oil, copper,
coal, iron ore and a raft of agricultural products
denominated in the greenback, the dollar has stayed
somewhat stronger than could be expected, based on the
U.S.’s weakened deficit condition. This may be changing for
the worse as the Chinese
yuan is finally left to float
against the dollar, after having
been artificially devalued for
years. This China seachange
has been caused by that
nation’s shift to internal
economic development,
necessitating expanded and
cheaper imports, while
Beijing’s exports have slowed
due to higher labor/benefit
and transportation costs. This
has significantly increased
China’s outward bound costs.
The Japanese yen has
maintained its strength due
to the “carry trade” which has
allowed currency traders to
borrow against the near zero
cost of the Japanese currency
and to profit by the higher
margins available from a
variety of global investment
opportunities.
While a historically strong
dollar has signaled an equally
sound U.S. economy, the
current aforementioned
circumstances have generated
a much more turbulent
volatility. l

The best K/BIS keynote
speech in the last 25 years

This was one of the best keynote
speeches that I have ever attended.
The subject was the connection
between the Internet, technology
and our industry. Michael E. Werner,
president and CEO of Globe Union
Group Inc., provided an overview of
how we should envision the future in
business and how technology
advances will alter the industry.
Werner addressed the ways that
technology impacts our current
landscape, how it has evolved and
how we can best prepare for
upcoming shifts. Through ongoing
advancements in technology,
everything has become possible,
accessible and more affordable.
Navigating and embracing the
redefined course of business as
industry professionals will ensure the
success of the industry. With proven
facts and evidence, Werner showed
the capacity-filled audience that the
Internet is a friend to all and that it is
not the case of “the showroom versus
the Internet.” If you think that
having a website is enough, you will
be surprised to learn what has
happened and what will take place in
the next couple of years. (Mary Jo

Tips for upgrading your
accounting system
BY ELLEN ROHR CONTRIBUTING WRITER
D
ouble-entry accounting hasn’t changed one bit
since the mathematical equation was codified
by 15th century Italian mathematician, Luca
Pacioli. Here is the accounting formula:
Assets = Liabilities + Equity
What you HAVE = what you OWE + what you OWN,
or
What you HAVE – what you OWE = what you OWN
58
Keeping this equation in balance is the function of
double-entry accounting. Assets have a debit balance;
liabilities and equity have credit balances: Debits =
Credits.
An automated accounting system is supposed to make
it easy for you to keep track of assets, liabilities, equity,
sales and expenses. You could do it all by hand. From
the 1400s until recently — in my lifetime — we all did.
Now, accounting software and iPhones and Tablets and
laptops and soon-to-be-extinct desktop computers make
short work of the addition, subtraction and division.
However, the universal laws of accounting always apply:
Debits = Credits.
Are you ready to make a move to a different
accounting software program? Perhaps you’re ready to
get an accounting program in place for the very first
time? Here’s some help for making a smooth transition.
Well, smoother than it might have been if you didn’t
read on.
• Pick an accounting software program. If you are a
small shop, under $750,000 in sales, use QuickBooks. I
would hold off on any industry specific software;
QuickBooks is a rock solid accounting program. For
larger shops, QuickBooks has limitations. It doesn’t have
a dispatching module or a good way to keep customer
history. So, consider an “add on” program that does
those things and can interface with QuickBooks. Or, you
can find an industry specific program that does it all;
the accounting, dispatch, customer service history…and
will make you a sandwich. (Just kidding about the
sandwich.)
Contact folks who are using the software you are
considering as part of your due diligence.
• Get thee to the Cloud. Consider a program that
connects via the Internet. You won’t need servers.
However, you are trusting your data to the Web. Plan to
regularly download and store your company
information on a drive and keep it in a fireproof safe.
• Pick a date for your transition. This is the date on
which you enter all data into your new accounting
program and stop entering data into the old program.
Pick the beginning of a year or a quarter. It’s easier to
make the switch at the beginning of your fiscal year,
because the income statement starts over every year.
Use the time between now and then to craft your plan.
• Follow the software guidelines. Honor the software
and the way it was designed. You’ll have more success if
An automated accounting
system is supposed to make
it easy for you to keep track
of assets, liabilities, equity,
sales and expenses. You could
do it all by hand. From the
1400s until recently — in my
lifetime — we all did.
you learn and follow the intentions of the
software developers as you proceed. Get transition
information from them and work together for best
effect.
There will probably be sample data in a “dummy”
company file. Go ahead and play around. That’s what it
is there for. Do the tutorials. Figure out how the
software works.
• Back up the old files. Create the option of restoring
to where you were before you started the conversion in
case something goes awry.
• Assemble the data you will need for the beginning
balances. What do you have for assets? For liabilities?
There will be verifiable evidence, such as bank
statements, credit card statements, loan documents,
invoices for asset purchases and the tax return. If you
had solid financial reports in the old system, it is a lot
easier to migrate to the new system.
• Create the new file. Always create the working file
of a new program on the last day of the previous year,
even if your transition date is in the middle of a year.
Enter ending balances in the balance sheet accounts as
of the last day of the last year. These balances become
the beginning balances for the current year.
• Update, upgrade your chart of accounts. Delete or
make inactive accounts that you don’t want or need.
Explore the options for organizing the data: classes,
departments, items and account numbers. Map out a
strategy for getting enough information about different
areas of your business (i.e.; big jobs, small jobs) without
overdoing it. Update the accounts and the setup screens
as needed.
• Enter customers and vendors. Unless you are certain
the data will come through in a useable fashion, don’t
bring the dollar transactions with the vendor and
customer files. Just bring over the empty accounts to be
populated moving forward.
• Create the AP and AR. As of the last day of last year,
enter any invoices that were created in the prior year
but not paid until the current year. Do this for vendors
and customers to create Accounts Payable and Accounts
Receivable.
• Get going! Enter data from the beginning of the
current year and get caught up ASAP. As you go, create
written procedures for the following data entry

Entering sales
•

payments
•

•
Entering bills
•

•

•

•

• Don’t bother setting up realtime inventory. Don’t connect the
inventory module. Expense
everything you buy to a cost of
goods sold (COGS) account/s. Plan
to count your inventory once a year,
or every quarter if you want to be
anal retentive. Then adjust the asset
of inventory and the COGS
account for materials to “right.”
• Regarding payroll…consider
using Paychex or ADP. Payroll is so
much easier to enter as a journal
entry than as an integrated process
in accounting. If you were doing inhouse payroll, you may still need to
wrap up the payroll liabilities
incurred prior to the switch. Find
out what was owed, what is owed
and adjust the balances to right
with your tax preparer’s approval.
• Reconcile the bank statements,
month by month. Use process in
the new accounting system for your
bank reconciliations. While you
might make a mistake in data entry,
if you get the cash accounts right,
you have a good chunk of the data
entry right.
• Hold off on integrating an “addon” customer service and/or
dispatch program until you are solid
with your QuickBooks file. Make
sure QBs is up and running and that
you can follow the flow of debits
and credits throughout the program
before you integrate another
program. Then be anal retentive as
you structure the setup so that you
understand the “hand-off” of data
from one program to the other.
• Involve your CPA or tax
preparer in the process. Bottom line,
the balances have to be right. The
accounts should reflect what you
have, owe and own. The accounting
should accurately record sales and
expenses. And the balance sheet as
of your last fiscal year should “foot”
to the tax return for that year.
Don’t stop until it’s right, current
and you understand it. Make sure
your CPA signs off on your plan and
your implementation.
• If you make a mistake, learn
from it. It’s a bummer to have to
redo or start over. Go ahead and cry,
if you need to, but keep going.
Remember that inside every
accounting program is the basic
accounting equation:
Assets = Liabilities + Equity
Once you understand this, you
can decipher any accounting
program. It’s like, once you know
how to drive, you can decide which
car best suits you. But essentially a
car is a car; an accounting program
is an accounting program.

The Solyndra Shame
BY MAX ROHR CONTRIBUTING WRITER
I
n 2011, a solar panel
manufacturer in California
named Solyndra filed for
bankruptcy and left 1,000 workers
jobless. Solyndra would have been
just been the story of a company that
tried to develop a unique nonsilicone photovoltaic panel and hit a
ditch when silicone prices
plummeted. The scandal that
followed was because Solyndra
received over 500 million dollars in a
rushed, guaranteed federal loan.
Some point out that this funding
project originated in 2005 with
bipartisan support during the Bush
administration. Regardless of the
start of this funding, the Obama
administration took the torch and
ran with it. They heralded Solyndra
as a prime example of future of
green collar jobs in America, made
speeches, and stood for photo ops at
the factory.
It is apparent that the Obama
administration and the Department
of Energy (DOE) put too many eggs
in one basket with Solyndra. Critics
show this as a prime example of
Chicago-style cronyism and bad
business sense at the taxpayer’s
expense. At the very least, it was a
hasty selection of a company to be a
poster child for a larger energy
agenda.
An always or never approach is
how solar funding seems to be
proceeding in the wake of Solyndra.
The Treasury Department was given
only one day by the DOE to review
the Solyndra loan in 2009. This lack
of diligence blew up in the DOE’s
face. However, now the DOE is so
gun shy that the 16.7 billion dollars
allocated for research and
development assistance is locked up
tight (WSJ 2012). The full throttle
or full break approach to energy
investment is toxic. Railroading
loans through is a bad idea. Not
funding anything on the possibility
that a particular company might not
be a home run is even worse. Even
in the event a company doesn’t live
up to its hype, that doesn’t mean
progress isn’t being made. Just think
of how many startups and small
businesses tried to build flying
machines over the years. We have all
seen grainy old videos of hilariously
ineffective flying machines. While
unsuccessful, they were part of the
important scientific process of
elimination.
Not all technology companies will
change the world, yet every company,
failed or successful, teaches a lesson.
What to do or what not to do are
both important to someone who
takes the time to learn why. A 500
million tax dollar loan shouldn’t be
handed to any company without due
diligence. It is an additional shame
when 1,000 jobs are lost. However,
it shouldn’t be forgotten that other
manufacturers can learn from
Solyndra’s mistakes and the solar
industry, nation, and world progress.
While Solyndra leaves a bad taste
in our collective tax paying mouths,
we can’t afford to continue our
current stagnant funding strategy for
solar energy research and
development. In 2009, the federal
government spent around three
billion dollars on energy research
according to an American Energy
Innovation Council (AEIC) study.
To give a sense of this funding as
compared to other sectors, the
National Institutes of Health
received 36.5 billion and defense
researchers received 77 billion. (I
would argue that investments in our
energy independence are actually
investments in our national security,
but that is another topic).
The harshest skeptics of the DOE
have deduced that government
money spent to aid the creation of
green jobs or products is a complete
waste. The Heritage Foundation’s
Morning Bell posted an article titled,
“Solyndra Scandal Ends Green Jobs
Myth.” Solyndra doesn’t prove that
green jobs are a hoax just like the
Ford Edsel doesn’t prove that all new
automobiles will be flops.
Additionally, the Solyndra loan made
up only 1.3% of the money given to
green energies that year (Washington
Post 2011). The other 98.7% of the
investments don’t seem to get much
media attention. The idea that green
jobs, as a sector, are worthless is the
narrowest of tunnel vision. I would
equate this logic to a man standing in
the middle of a desert next to a
barrel of water and laughing at
anyone who decided to leave and
look for more water. The amount of
water in the barrel doesn’t matter, it
will one day run out.
The shame of Solyndra is that it is
a black eye on the face of solar
energy research. As a 26-year-old,
there is a possibility I will see oil dry
up in my lifetime. As a country, we
can’t afford to let solar energy
research and development be shelved
or underfunded. The amount of coal,
oil, and natural gas left on earth is
not easy to nail down in a terms of
years left. It is with absolute
certainty that we have a finite
amount of oil, coal, and gas on Earth
and more developing countries are
ramping up their consumption. The
sun will shine on the day we use the
last drop of oil. Whether or not we
are prepared for that day is what we
will decide in the next few decades.
If we stop funding solar with public
or private dollars, we are doing a
disservice to our future. Solyndra
was a failure, but the solar sector is
still worth backing. I would rather
my tax dollars go to companies who
search for new ways to harvest free
clean energy than to someone
standing next to a barrel of water in
the desert. I won’t defend the
decision to fund Solyndra with so
much money, but I hope that it
doesn’t become an excuse to not
look for future energy in the sun. l

Bristol’s Six Principles for Good Solar
Hydronic Design #47: Piping the solar
collectors with flexible tubing
BY BRISTOL STICKNEY CONTRIBUTING WRITER
T
64
he best innovations in solar heating systems in
recent years have evolved by combining preengineered and pre-assembled components. When
multiple components are matched and assembled during
manufacture, it eliminates the labor of assembly and the
high potential for error in the field. In solar home heating
systems, the use of modular heat distribution manifolds
and pre-engineered pump stations, for example, has
gained in popularity because of the speed of installation
and the increased reliability of the results.
Another area where modular equipment is now
available is in the solar connective piping itself. The
insulated (metal) supply and return piping that connects
the solar collectors to the boiler room must be resistant to
very high temperatures. The outdoor runs must be
resistant to weather and sunlight. The path of this piping
often runs through tight spaces with awkward angles and
bends. Traditionally, this piping has typically been done
with copper tubing in a meticulous three-step process
The best innovations
in solar heating
systems in recent
years have evolved
by combining preengineered and
pre-assembled
components. When
multiple components
are matched and
assembled during
manufacture, it eliminates
the labor of assembly and
the high potential for error
in the field
involving (1) soldering copper pipe
together with couplings and elbows, (2)
installing the insulation and (3) finishing
with a weatherproof cover. The use of preinsulated flexible piping can eliminate most
of that work in the field, saving many hours of installation.
Flexible stainless steel insulated pipe
Figure 47-1 shows the construction detail of a stainless
steel solar supply and return pipe assembly using an
example available from Caleffi Solar. It consists of two
corrugated stainless steel pipes inside an EPDM closedcell foam insulation jacket with an integrated sensor wire
built in. It is most commonly packaged in 50-foot coils.
The insulation is coated with a copolymer foil that
protects against damage from solar UV radiation. It comes
in three common sizes, ½”, ¾” and 1”
nominal pipe sizes. This modular tubing
is lightweight and easy to bend, with a
springy feel to it. The two corrugated
pipes are made of 316L stainless steel
with a bending radius of 5 inches, a
working pressure rating of 150 psi and a
maximum fluid temperature of 350 F.
The stainless tube can be cut using a
tubing cutter, the same as that used
with copper tubing. It requires special
adapters at each end to allow
connection to standard U.S. pipe thread.
Adapters are available from suppliers,
and it is always a good idea to order a
few extra to have on hand in the field.

GREEN SYSTEMS
The adapters that I have used so far are surprisingly fast
and easy to install and “act like” a threaded brass union
with a flat gasket when making the final pipe connection.
Short pieces can be cut and fitted with adapters to make
other connections to the glycol system or to other boilerfluid piping.
66
The pressure drop
Because the tubing is corrugated, the inside surface has
a rough finish, which results in a higher pump resistance
than smooth copper tubing. This must be taken into
account when designing the solar glycol loop and the
glycol pump to go with it. At common glycol flow rates
to the pump resistance due only to the
supply/return piping. Other plumbing
components, such as collectors, heat
exchanger, shut off valves, elbows and
other fittings that provide additional
resistance must also be included to
obtain the total pressure drop for the
entire glycol loop. The circulator pump
must be sized to overcome the total
resistance to flow.
The glycol mixture and its average
temperature have a significant effect
on the pump resistance. Figure 47-2
covers a typical mixture and
temperature (as labeled), but colder
temperatures or thicker mixtures (for
example) will have different results.
Figure 47-2 presents the flow through a pair of pipes,
one supply and one return. This means that a 50-foot long
sample actually contains 100 linear feet of pipe.
Sometimes you have to look at the labels or fine print
carefully to avoid comparing a single pipe to a pair of
pipes when looking at the flow resistance of different
products or brands.
Final notes
These articles are targeted toward residential and small
commercial buildings smaller than 10,000 square feet.
The focus is on pressurized glycol/hydronic systems, since
these systems can be applied in a wide variety of building
geometries and orientations with
few limitations. Brand names,
organizations, suppliers and
manufacturers are mentioned
only to provide examples for
illustration and discussion and do

square feet. The focus is on pressurized

be applied in a wide variety of building geometries
and orientations with few limitations.
for solar collectors, the difference is in the range of 20 –
30 percent higher pump resistance than in comparable
smooth pipe. Figure 47-2 shows how the corrugated
stainless compares to copper tube, using the Aeroline
products, for example. Aeroline makes pre-insulated
smooth copper tubing, assembled in the same way as their
stainless steel product, so a direct comparison can be
easily made.
For example, on Figure 47-2, a flow rate of 5 gpm
through a pair of ¾” tubes 50 feet long requires about 10
feet of head to pump through copper (seen as a red line
and labeled “CU”). The same flow rate through
“Aerorapid” corrugated ¾” pipe requires over 12 feet of
heat (seen as a blue line). If 1” corrugated pipe is used
with the same flow rate, less than 4 feet of head is
required.
Figure 47-3 shows the pump head available from a
common Grundfos 3-Speed circulator. Notice that, for
this example, at 5 gpm the 1” corrugated could be
pumped at low speed and the ¾” copper could be
pumped at medium speed, while the ¾” corrugated may
require high speed.
Other considerations
Remember that the discussion above has been limited
Bristol Stickney has been

repairing and installing solar hydronic heating systems for
more than 30 years. He holds a Bachelor of Science in

contractor in New Mexico. He is the chief technical
officer for SolarLogic LLC in Santa Fe, N.M., where he is

In this series of articles, I have been making the case
that the key ingredients for solar/hydronic design and
installation can be divided into six categories, roughly
in order of their importance.
1. Reliability
2. Effectiveness
3. Compatibility
4. Elegance
5. Serviceability
6. Efficiency
The success of any solar hydronic home heating
installation depends on the often-conflicting balance
between any of these six principles. Finding the balance
between them defines the art of solar heating design.

innovations to drainback systems
that build on the expectations that
most solar design builders desire;
flexibility, simplicity, longevity and
economy. The information about
advances in drainback noted here
results from speaking with industry
specialists throughout North
America who have a thorough
working knowledge of these systems
and, in many cases, have determined
that drainback is the optimal choice
in solar hot water collection. This
opinion is shared by “new”
generation solar designers who work
with both custom closed loop and
drainback system designs.
I work closely with a young
design engineer named Russell. He
makes it clear to me that drainback
is simpler to design, requires less
maintenance and is installed at a
lower cost. At 26, Russell has five
years experience in active solar
design, primarily with commercial
closed loop systems. He is a sensible
designer who understands the
advantages and disadvantages of
drainback and closed loop systems
and prefers to design for drainback
when the option is available.
Designed for “fail safe”
Drainback is regarded as a “fail
safe” system. The collectors remain
empty outside of collection cycles.
Empty collectors are protected from
freezing water breaks in the cold
season or from steam generated by
high temperatures of the transfer
fluid. Because they are empty, there
is no harm to the collectors when
the system is not operational.
In contrast, closed loop systems
contain a circulated pressurized
glycol solution that requires vigilant
maintenance. To prevent stagnation
of the working fluid, more attention
to detail is required. In order for
closed loop systems to be
fail safe, the glycol would
have to be contained or
drained if the pumps shut
down, and a shutdown
would possibly need to be
followed up by a service
call.
In a closed loop system,
the collectors can be
installed anywhere in
relation to the solar tank or
heat transfer. Collectors for
drainback, on the other
hand, must be mounted
above the drainback
reservoir, although not
necessarily above the solar
storage tank. Drainback
works well with most roof
mounted collectors, since
the working fluid can drain
back by gravity into the
reservoir. To ensure draining
by gravity, drainback design
should include the
specification that there
should be no slope ratio on
the collectors and that
piping be secured dead level
to a roof.
It is advisable to add
freeze protection
(propylene glycol) to the
drainback reservoir to
prevent the potential freeze
that could occur if the array
piping sags over time. Dead
level installs are often used
for rooftops with large
collector arrays and large
diameter supply and return
piping. An excellent
example of dead level
drainback is the largest
domestic hot water system
in the state of Wisconsin,
located at the Kalahari
Resort in Wisconsin Dells.
The rooftop is home to 104
vertically-mounted flat
plate collectors installed
dead level.
horsepower can be expensive.
Overcoming lift can be an expensive
problem when drainback reservoirs are
installed in a basement or on a lower floor of
a high-rise building. To avoid this problem,
the drainback reservoir should be mounted
at a high elevation, such as on the top floor.
The system pump does not have to be raised
with the drainback reservoir but can be
installed in the mechanical room with the
controls. Installing the reservoir somewhere
below the rooftop under the freeze line will
allow you to take advantage of smaller pump
sizing. I have heard of drainback designs
including ridiculously large and very
expensive pumps because the engineer did
not understand that pump lift requirements

Efficiencies gained
Savings in drainback
pump first cost and
operating costs can be made
when selecting the
drainback reservoir location.
A drainback pump has to
lift a column of water from
the reservoir to the top of
the collectors. The greater
the height of the lift, the
greater the pump
horsepower needed. High
lift and greater pump

are smaller if the reservoir in a tall
building is at a high elevation.
Another option for savings is to
have two pumps installed on the
drainback loop. At start-up, pump 1
energizes to “on” and pump 2
energizes with an “on, time delay to
off” sequence. At start-up, both
pumps are needed to overcome
total lift; to push the air bubble out
of the collectors and into the
drainback reservoir. Once the air has
been displaced into the drainback
tank, considerably less lift is
required for circulation. The
pressure drop requirement is
lowered and system circulation
becomes comparable to a closed
loop system. Once water is flowing
throughout the loop, the second
pump is “time delay to off” until the
next cycle of solar collection begins
and total lift is required once again.
This option allows for the use of
smaller, less expensive pumps and
increases electrical efficiency.
A variety of options are available
for the mechanical transfer of
energy from the drainback reservoir
to the solar storage tank. Drainback
thermal transfer may include a heat
exchanger in the drainback tank, a
heat exchanger in a hot water
storage vessel or an external heat
exchanger.
Drainback reservoirs are sized
large enough to displace the volume
of air in the collector loop with
water while maintaining a flooded
drainback pump. If there is a coil
heat exchanger in the drainback
reservoir, it must be completely
submerged during the collection
cycle. Normally a site glass on a
drainback reservoir is used as a
gauge for fill. Drainback reservoirs
are manufactured in 10-, 15-, 20-,
40- and 60-gallon sizes, with
stainless steel tanks.
Reservoirs for larger arrays may
be piped together in parallel to
accommodate volumes over 60
gallons or when port capacity
requires more flow (port size may
be limited to ¾ or 1 inch). It is
standard practice to install the
drainback reservoir on a wall stand
above the solar storage tank. This
helps position the drainback pump
below the bottom of the reservoir.
The pump should be installed
vertically and should pump against
gravity to avoid pump cavitation.
For better pumping characteristics, a
drainback loop can be sealed closed
so that it is airtight and the entire
loop charged to 10 psi or more.
Pressurizing a drainback closed loop
raises the boiling point while
compressing entrained air out of the
working fluid during circulation.
For larger systems with an
external heat exchanger, two pumps
may be incorporated on the
drainback reservoir; one for the
solar collector loop and the second
for the reservoir heat
exchanger loop. This
design separates two
(usually high) pressure
drops into two loops.
Separating the loops
helps size for smaller
pumps and enables a
more efficient control
sequence for heat
transfer, since the
drainback tank can now
be first “primed” with
heat, prior to transfer to
the solar storage tank.
External heat
exchangers allow for
additional flexibility
with the installed
location of the solar
storage tank. Since
pressurized water is
circulated from the heat
exchanger to the solar
storage tank, the solar
tank can be installed in
any location relative to
the drainback tank.
Limitations may occur
for long pipe runs and
heat loss but, if
necessary, a solar storage tank may
be installed above the collector
height.
Many early large drainback
systems had insulated fiberglassreinforced plastic tanks, which are
still quite popular today. Water
from these tanks flows directly into
the collectors. These tanks contain
stainless steel or copper heat
exchange coils sized in length to
accommodate a large enough
surface area for a sole pass high
temperature rise. As an example,
cold water is preheated through the
submerged coils in the atmospheric
tank, raising the cold inlet
temperature close to the solar tank
temperature en route to the backup
water heater.
Active solar hot water heating
designed properly is an efficient
method to collect, store and
distribute solar thermal energy. As
the solar thermal industry matures,
drainback will most likely gain
higher ground and increased market
share for commercial systems due to
the most basic demand of building
owners and their maintenance staff;
desire for a high performance
system with a long life cycle,
designed for low maintenance and
priced for value.
Owners may be uncomfortable
with a closed loop system if the
building’s hot water load varies or
shuts down from time to time, such
as in a school. Those manufacturers,
designers and installers who don’t
get involved with drainback will do
just fine with closed loop system
design and installation. But those
who have a complete knowledge of
both system types have an
improved opportunity to satisfy
their customers’ requests for the
simplicity drainback systems
provide.
Both closed loop and drainback
systems will satisfy performance
expectations when designed and
installed correctly. The question is
which system is better suited for a
specific commercial application and
hot water load variations. Drainback
could provide simple solutions to
some of the
complex issues
closed loop
systems
present. l

Mesenbrink as he moves on to another venture,
and at the same time to welcome Jim Schneider,
who assumes John’s role as editorial director of
Phc News, as well as its sister publication,
Plumbing Engineer. Jim’s comittment to editorial
quality and consistency is unmatched, and we
feel that his expertise will guide both magazines
to new heights.
Jim has been working in trade publishing for
almost 15 years. He began his career in education
publishing, serving as the managing editor of
T.H.E. Journal, a monthly educational
technology magazine based in Tustin, Calif., from
1997 to 2001. In 2007, Schneider came on board
at the Chicago office of Washington, D.C.-based
construction publisher Hanley Wood as senior
editor of Eco-Structure, a green-building
magazine, and Metalmag, a metal design and
construction magazine. In this role, he worked
with contractors, engineers, and architects to seek
out, write, and develop relevant content for the
magazines. In 2009, he was promoted to lead
editor of Metalmag, and became solely
responsible for that brand’s content, while
