14 PVC or CISP?
William Morris
Plumbing designers frequently face a choice between PVC and
cast iron for commercial underground drainage applications.
Unfortunately, the perfect drainage material for all applications
does not exist. This article explains the performance properties
of PVC and cast iron soil pipe drainage systems to aid plumbing
designers in material selection.
40 Case Study: Domestic Water System Design
28 High-rise Plumbing Design
Dennis M. Connelly, CPD
NFPA defines a high rise as a building with an occupied floor that is 75
feet above the level where firefighters stage operations. With that simple
definition, all high-rise design challenges should be the same, right? The
author discusses why the answer is not always clear cut.
for High-rise Buildings
Jim Beveridge, P. Eng.
Providing domestic cold and hot water to the upper floors provides the
main challenge for the plumbing system engineer for a high-rise building
project. In this case study, the author describes the various parameters the
plumbing engineer must consider in overcoming this design challenge.
