Rob Lloyd, Piping Systems Consultant of Lubrizol gave our group all the highlights of CPVC piping systems. Once again, thank you, Rob and Bill Hutchinson of BWA South, for a most informative presentation. ● On Friday evening, May 20, our Chapter will converge on Fifth Third Field in downtown Dayton for our annual Night with the Dayton Dragons. This year, the Bowling Green (KY) Hot Rods (Class A affiliate of the Tampa Bay Rays) will provide the opposition. Preparations are in full swing, with Ticket and Food Sponsors very much needed. To sign up for one of these important programs or for additional information, please contact our Fundraising Chair, Jeff Watern of Helimg Lienesch, at 937.228.4007 or at [email protected] ● Spring is here and here’s hoping you will be able to join us for the April meeting, when we learn about propane gas systems. I hope you will make plans to join us, whether in person or WebEx, for what promises to be yet another informative get-together. -Ronald K Bartley, PE, CPD, CPI/CPE Through the pipes… ● Time is running out to apply for ASPE's Board of Directors. To run for one of the 12 national officer positions for the 2016-2018 term, you must complete the application and submit it to the Nominating Committee by May 31. ● The Society is now accepting proposed changes to the current ASPE Bylaws. Please submit changes to Executive Director/CEO Billy Smith at [email protected] by June 30, 2016. Final Proposed Bylaw Amendments will be presented to the membership by September 13, 2016 ● In May, Plumbing Engineer magazine is spotlighting the hospitality market and is looking for technical engineering and design articles on the subject to feature as the cover story as well as two-page spreads. Submissions should be 1000-1500 words, to four high-quality images, graphs, or charts, and have limited usage of bulleted or numbered lists. Submissions will be accepted through Friday, April 8, via [email protected]. Please note: This opportunity is not open to manufacturers supplying product-specific case studies or advertorials. ● On October 28-November 2, #ASPEflowswest to Phoenix for the year's biggest industry tradeshow dedicated uniquely to the needs of plumbing system designers, engineers, specifiers, and contractors. If you are planning on attending, check out our new Toolkit (on the Society website), which is full of ideas on how to maximize your experience cost-effectively. To learn more about the exciting events planned, watch our new video featuring ASPE Executive Director/CEO Billy Smith, FASPE. Registration will open in May at aspe.org/ecpo. ● ASPE's new Mentoring Program matches emerging industry professionals with established leaders. The Women of ASPE are excited to introduce ASPE's new Mentoring Program, which is available to all ASPE members in good standing. The program is designed to connect ASPE members who have a particular skill set (mentor) with individuals who are looking to acquire the same skills to develop and make progress toward their personal and professional goals (mentee). You can learn more and sign up to be either a mentor or a mentee at aspe.org/aspe-mentoring-program. If you have additional questions about the program, please contact Stacey A. Kidd at [email protected]. ● Education experts are needed to help develop plumbing engineering curriculum. ASPE is interested in collaboratively developing a Bachelor of Engineering with an emphasis on plumbing engineering or expanding an existing Bachelor of Engineering degree curriculum to include plumbing engineering as a technical option. For more information or to participate, contact Donna Novickas at [email protected]. Specifically, we are interested in: Partnering with a college/university that currently has ABET accreditation Utilizing curriculum experts in the engineering area to develop a curriculum that prepares candidates for successful completion of the NCEES-sponsored Professional Engineer exam Developing a National Science Foundation (NSF) grant proposal for October 2016 ● ASPE is looking for interested parties to help develop an American National Standard on hot water temperature and control. For the application form, contact Director of Publications and Standards, Gretchen Pienta, at [email protected] for more information. ● On Saturday, March 12, the State MATHCOUNTS Competition was held at Columbus State College. Middle School teams and individual competitors squared off to see who would represent the Buckeye State in the National Competition on May 7th in Washington, DC. Among the competitors from the Dayton Region, Magsig Middle School (Centerville) placed eleventh in the Team Competition. Congratulations on a great 2016 completion, Magsig Mathletes! ● Did our Chapter make it to the Second Round of the ASPE Chapter Membership Tournament? Unfortunately, despite VPM Ron Cobb’s best efforts, the San Diego Chapter (our competitor for the Opening Round) posted a larger gain in membership which advanced them to the Second Round to face the Oklahoma City Chapter. So it was off to the Consolation Round for us, where we faced the Miami Chapter. While both Chapters posted the same increase in membership, the Southwestern Ohio Chapter won the tie breaker in that we posted no loss in membership during that time. So during March/April 2016, we are matched against the Denver Chapter. Let’s see if we can increase our membership numbers and create our own Rocky Mountain (or is it Ohio Valley) high! Around the water cooler… ● Welcome again, Coolers. April showers bring May flowers…and more plumbing and fire suppression items for us to ponder. A couple of months ago, we kicked around a question concerning the placement of food waste disposals. Let’s check out a follow-up to that discussion… Is it against code or inappropriate in any way to install a garbage disposal in a church building breakroom sink? I haven’t done it before and we are being asked to specify one on a project. It looks like the plumbing code refers to them as domestic food waste grinders and requires them to have a water connection with backflow prevention. Anything else unique about food waste grinders that I need to watch out for? Unless the local Authority Having Jurisdiction has some restriction, no there is no code prohibition in the OPC about a food waste disposal. However, you are actually asking two questions: one about disposals in general and one about commercial disposers. Most residential disposals (which are typically used in breakroom sinks) do not have a water connection, except the sink faucet itself. However, commercial disposers are generally mounted in a “pre-rinse” bowl or well. It is the “pre-rinse” bowl or well that has a water connection. And yes, the water connection needs to be protected against backflow or back siphonage (usually by an atmospheric vacuum breaker). You may want to discuss the use of garbage disposers with the local sewage waste treatment provider, specifically the “pretreatment coordinator”. There has been an effort by some wastewater treatment providers to eliminate or greatly restrict the use of garbage disposals. Their concern is the introduction of undigested organic materials into the waste stream. These materials tend to plug up some equipment and create maintenance issues within the treatment process. ● “How big is too big…when it comes to water closet drains?” That’s the question we have here… I have always designed underground sanitary serving water closets to be 4". I just had a contractor question if they could reduce the size to 3" based on Table 710.1 in OPC. This table allows for 36 DFUs at 1/8" slope which translates to 9 WCs before it needs to increase to 4". I remember in an older version of the code that no more than 2 water closets could be on a 3" line. Can you please elaborate on this? As it turns out, you and the contractor are both correct. In a previous edition of the OPC, there was a provision that no more than 2 water closets could be placed on a 3" line; that provision is no longer in effect in the current code. And the contractor is correct that Table 710.1 (Building Drains) does provide for 36 DFUs for a 3” line. Per Subnote a, the size of the drain from a water closet shall be a minimum 3". Table 710.2 (Horizontal Fixture Branches and Stacks) places no restrictions on the number of water closets on a 3" line other than a maximum of 20 DFUs for a horizontal drain. There are trade-offs between the two sizes. A 3" drain from a water closet can be more prone to blockage where a 4" drain can have issues with drainline carry (especially with the lower flow fixtures in use today). It is a judgment call on the part of the engineer/ designer. ● Power to the people…or, at least, emergency power to the building. That is the topic broached by a Cooler. Read on… Is there anything in NFPA 101, Life Safety Code, which addresses emergency power systems and the acceptability of natural gas or LPG as a fuel source? A question has come up on what is required for the healthcare project I am working on. This is, at first glance, a common question. But there is nothing common about the answer. A check of NFPA 101 offers the following items… 9.1.3 Emergency Generators and Standby Power Systems. Where required for compliance with this Code, emergency generators and standby power systems shall comply with 9.1.3.1 and 9.1.3.2. 9.1.3.1 Emergency generators and standby power systems shall be installed, tested, and maintained in accordance with NFPA 110, Standard for Emergency and Standby Power Systems. 9.1.3.2 New generator controllers shall be monitored by the fire alarm system, where provided, or at an attended location, for the following conditions: (Article 700) and legally required (Article 701)… 1) Generator running 2) Generator fault 3) Generator switch in non-automatic position 5.6.1 So switching to NFPA 110, we find the following concerning acceptable types of fuel… 5.1.1 The following energy sources shall be permitted to be used for the emergency power supply (EPS): (2) Liquefied petroleum gas (liquid or vapor withdrawal) as specified in the appropriate ASTM standards and as recommended by the equipment manufacturer. (3) Natural or synthetic gas. Chapter 5 of NFPA 110 also offers a few specifics on dedicated supplies, on-site storage and the like. Don't forget that gas-fueled generators typically have lower power outputs than those units that are supplied by fuel oil. From the NFPA 110 Handbook (highlight ours)… 5.1.1 Exception Although on-site storage is common, on-site storage of the requisite amount of fuel is not directly required except as covered by the exception. Approval of an off-site fuel source is a matter that can be addressed only by the Authority Having Jurisdiction (AHJ). Ideally an on-site fuel source should be provided, which is the norm when using diesel or liquefied petroleum gas. The use of an onsite supply minimizes the disruption of the fuel supply. The supply should be sufficient for the EPS to operate, for the duration of its class, at its rated load without refueling. Natural gas is often piped in, and the exception for a Level 1 EPS permits this method unless there is high probability that the supply will be interrupted… 5.2.5 The NEC has two specific for standby power systems addressed by NFPA 110: emergency Since NFPA 110 is primarily a performance document, it is expected that the installation of the prime mover (combustion engine, gas turbine, etc) follow the general requirements of NFPA 37, Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines for the other aspects of EPS installation… And if we turn our attention to NFPA 70, we find a few more items to consider… 700.1 Scope Informational Note No. 2: For further information regarding performance and maintenance if emergency systems in healthcare facilities, see NFPA 99-2012, Healthcare Facilities Code. 700.12 General Requirements B) Generator Set (2) Internal Combustion Engines as Prime Movers. Where internal combustion engines are used as the prime mover, an on-site fuel supply shall be provided with an on-premises fuel supply sufficient for not less than 2 hours full-demand operation of the system. Where power is needed for the operation of the fuel transfer pumps to deliver fuel to a generator set day tank, this pump shall be connected to the emergency power system. (3) Dual Supplies. Prime movers shall not be solely dependent on a public utility gas system for their fuel supply or municipal water supply for their cooling systems. Means shall be provided for automatically transferring from one fuel supply to another when dual fuel supplies are used. Exception: Where acceptable to the authority having jurisdiction, the sue of other than onsite fuels shall be permitted where there is a low probability of a simultaneous failure of both the on-site fuel delivery system and power from the outside electrical utility company. 701.1 Scope The requirements for legally required standby systems are much the same as for emergency systems, except for a few differences. When normal power is lost, legally required systems must be able toi supply standby power in 60 seconds or less, instead of the 10 seconds or less required of emergency systems… At the watering hole… ASHRAE. The tour will be led by the facilities manager, and will follow the May ASPE Chapter Meeting, at 1:45 pm. We hope that this will enable more of our Dayton members to attend, as they will already be in the area for the meeting. Afterwards, feel free to return to work, or come up to Short Vine and have a drink and chat. Hope to see you then! -Andrew M Hemmelgarn Regionally affiliated… ● On March 11th, World Plumbing Day was celebrated. And to commemorate the occasion, I spoke that day to students at Parker Woods Montessori School (pictured above), spreading the word about our discipline in general and ASPE in particular (after all, inquiring minds wanted to know). ● On March 15th, the Southwest Ohio Young Professionals group met with the local ASHRAE chapter for a tour of Rhinegeist Brewery (again, pictured above). The tour went extremely well, with all members leaving with a greater understanding of the engineering behind a brewery and a beer! Group discussion followed as members continued to meet one another and foster new relationships. ● The next AYP event will be a joint tour of the University of Cincinnati’s onsite power plant with the Young Professionals group of In my article last month, I told you about “The State of The Society” video presentation by Mitch Clemente. I hope you had a chance to view it. If not, please visit this YouTube link to watch his ASPE video, https://youtu.be/GrgEMxM792 M. There is a wealth of knowledge packed into one-half hour. Left standing in the Sweet 16 round of the ASPE Chapter Membership Tournament, we have Toronto. Eastern Michigan lost to Philly by just 0.68%. It is nice to know our remaining Chapters in contention are on opposite sides of the bracket. Toronto takes on Virginia Blue Ridge to enter the Elite 8. Come on Region 2, we are rooting for you. If you read, the recent ASPE Pipeline last week you might have read about a cat that slipped out of the bag prior to an official press release, so I can now inform you that ASPE and NSF International have signed an MOU. Under this agreement, both organizations will work cooperatively on many fronts and are very excited to give ASPE members access to so much new information. We can elaborate on this opportunity once the press release is official. Stay tuned. I travelled to Evansville, IN recently to take part in the third annual joint ASPE-JATC trade show at the UA Local 136 training center. It was an incredible event. There were upwards of 425 apprentices, instructors, and building officials that visited our manufacturers. I was honored to able to take part in this event. It was such a huge success; make plans to attend the fourth annual joint ASPEJATC trade show in Evansville. To top off the week, I was invited to present an In-Depth Look into NSF to our Evansville ASPE members. I count my blessings every day. Here are (L to R) Greg Farmer PE, VP Tech and Samuel Schenk, CPD and Satellite President Apprentices lining up to register and visit vendors. Apprentices making their rounds. - Dann Holmes ASPE Region 2 Affiliate Liaison NSF International Business Development Manager [email protected] or (734) 214-6222 March and April will determine the winner and see who advances on. Stay tuned, we are still alive in the Consolation Bracket. VP Membership… Spring is finally here and it’s time to start thinking about golf and baseball. In additional there’s a national basketball tournament that has just been whittled down to the final four. Unfortunately, none of our local teams have reached the final weekend. Speaking of tournaments, I would like to give everyone an update on the ASPE membership challenge and the inaugural Chapter Membership Tournament. For the months on November and December 2015 our chapter membership remained the same with 0% growth and we were defeated by the San Diego chapter which achieved a 1.22% growth. But the membership challenge did not end there. We were placed in a consolation bracket for the months on January and February 2016 and were paired against the Miami chapter. Once again our membership remained unchanged at 78 members but the same was true down in South Beach. Since both chapters experienced no growth they had to revert to the tie breaker system and since the Southwestern Ohio chapter was never negative in growth over the two month period we were deemed the winner and have advanced to the next round to face the mighty Denver chapter. Results of membership growth for the months of Even though the chapter membership has not grown over the last few months, we have added a couple of new members. Jamie Renner, a former member has recently rejoined the ranks. Jamie works at Keidel Supply, a stock and distributor company of plumbing products in the Cincinnati area. Also welcome aboard Deana Thompson. Deana is a Plumbing and Fire Protection Designer working in the Commercial and Helthcare divisions for Kerr-Greulich Engineers in Louisville, Kentucky. Our current chapter membership remains steady at 78 which include 45 Full, 6 Associate, 19 Affiliate, 6 Special members and 2 Retired members. Ron Cobb VP Membership
