Introduction to Issue #31

This issue of idronics discusses several scenarios where the pressure within modern plumbing systems is higher than desired for a variety of reasons. It then examines how to correct those situations through proper design and use of pressure regulating devices. The resulting systems reduce water waste, mechanical stress on plumbing components and noise.

2: PLUMBING SYSTEM PRESSURE CONCEPTS

One key consideration in designing a building plumbing system that maintains acceptable pressure at fixtures is the pressure available at the location where water enters the building. Pressures that are either too high or too low at the point of entry can be caused by several factors.

3: APPLYING PRESSURE REDUCING VALVES

One of the most common applications is as a point-of-entry pressure regulator on the cold-water service pipe supplying a building. This section describes preferred locations, maintenance, and other troubleshooting scenarios.
