How is the DWV rough in pressure test done?
Sarah Marsh How is the DWV rough in pressure test done?
P2503.5.1 Rough plumbing. DWV systems shall be tested on completion of the rough piping installation by water or for piping systems other than plastic, by air with no evidence of leakage. Either test shall be applied to the drainage system in its entirety or in sections after rough piping has been installed, as follows: Air test.
What do you need to know about rough in plumbing?
A roughed-in bathroom or kitchen typically has capped PEX or copper water supply pipes jutting up through the floor or wall. Drain lines often are covered to prevent debris from entering. A rough-in plumbing installation will need to be pressure-tested before it is deemed complete.
