That’s what I’ve been wondering. In the one municipality that requires it, IIRC, and I could be wrong, but I think they want to see 15 psi hold for 15 or 20 minutes.we have to test with air or water. hard to test with water in winter or when there is no water on the job. how many psi was on the pipe when it exploded?
Bullshit,been doing it for 26 yrs and never had an explosion,what jackass puts enough pressure to burst a pvc pipe in the first place???if you use water in ky it has to have a 10 ft head on it and I've seen geysers come out of unglued joints and ruin houses and materials
We do it all the time and I see a lot of garages and shops with pvc air lines run everywhereYears ago down in West Palm Beach, FL we air tested 2" copper. I was a young apprentice and I was working with a journeyman plumber. We had roughed-in all the PVC and copper for an electronics store that was being built. I think it was a Best Buy, but I can't remember for certain.
The journeyman had a leak on the overhead 2" copper that was very easy to fix since there was no water in the pipe. I think that he soldered all the piping, I was still green and I don't remember soldering. It's so much easier to repair copper with air in the line for the test as opposed to water. But never, ever, ever test PVC with air.
The 5 to 30psi you might use on NEW pvc for 24 hours tops is nothing of a hazard compared to pvc used for airlines for years at 100psi+. I guess 1/2" CTS schedule 80 would be fine but anything other than that I definitely wouldn't use for air lines because IF it did burst it would shatter and send sharp pvc bits everywhere.We do it all the time and I see a lot of garages and shops with pvc air lines run everywhere
Maybe in the Country of Chicago they still use air. Here in Southern Illinois your lucky if a test is required on DWV, water yes. Head test on Fed projects or "if" required. Peppermint oil is still acceptable.It used to be a acceptable test in Illinois don't know if it still is.I remember having a test on at 5lb. and hearing a leak on a 2" Cherne plug on a floor drain,reached down to give it another twist and it let loose,never found the test plug it flew so far as it zipped past my head.
There was a Local 130 guy killed a few years back air testing some 5" galv. down in Chicago.
In the United States OSHA prohibits the use of pvc for pressurized air Safety and Health Information Bulletins | The Use of Polyvinyl Chloride (PVC) Pipe in Above ground Installations | Occupational Safety and Health Administration
It’s very dangerous.
I am a service plumber who gets bored and wishes to spend his free time discussing plumbing and occasionally making smart azz comments..................Who are you and do you run this board ?
How do y’all test with peppermint oil?? I’ve used it to locate a leak before and we poured it in the roof vent with about 5hallons of water behind itMaybe in the Country of Chicago they still use air. Here in Southern Illinois your lucky if a test is required on DWV, water yes. Head test on Fed projects or "if" required. Peppermint oil is still acceptable.
