Performance should include a water-pressure test by
- selecting from among various water pressure gauges
- tightening the gauge on an open spigot
- ensuring the pressure is within normal range, according to code (pressure may fluctuate over time)
- turning on another supply that will pull demand
- checking the original gauge to determine whether the pressure drop is within normal range
Performance should include an air pressure test by
- following manufacturer directions for using an air pressure pump and gauge at no more than 5 pounds per square inch (psi)
- determining whether plumbing maintains pressure.
IRC: Chapter 29 (https://codes.iccsafe.org/content/IRC2018P4) covers water pressure testing.
Process/Skill Questions:
- At what pressure should an air test be conducted?
- What materials are needed to perform the test?
- Who checks the tests on the piping?
