What length of unthreaded one inch gas pipe should be exposed when stubbed out from a finished wall
Dje530:
You need to tell us more than that... ;)
You said UNthreaded..? Why..? Not attaching anything?
Stubbed out from finish wall..? Why?
Let us know more. Thanks.. Mark
It's a question on a plumbing quiz and I don't know the answer. NO othe rinfo
Got to be a trick question! I'm going after this question the practical way. Since the pipe coming out of the wall's unthreaded black iron pipe and compression fittings can not be used a thread must be put on that bald piece of pipe.Quote:

While this probably isn't the answer they want this is the one that will get your gas appliance connected. Good luck on your test. Tom
