testing plumbing drain systems for inspection
Just called the inspector regarding either air or water testing for the drain and vent system for a new house. He was very nice and tried to be helpful, but it was difficlut to get a complete picture of what he was saying.
Does anyone have a source which would explain exactly how to and preferabley the easiest way to cap all drains, toilet flanges, shower pans etc. to either air or water test a system?
I think they sell knock toilet flanges, you don’t see that many so maybe they are not all that great. Are there rubber balls or seals you can use? Since either and air test or a water test is allowed, which is easier.
