Excuse me barging in on an inspectors-only board, but I’m a homeowner with a code question and my local inspectors haven’t answered my emails.
I was going to use one of these PVC over-hub couplings to save a bunch of work and materials on a plumbing project in my house, when a plumbing contractor friend of mine said it might not comply with code. He couldn’t give me a good reason why it wouldn’t pass inspection, just that he’d never used one before. I didn’t want to go ahead and use it, then have to tear everything out and start over, so I thought this forum would be a good place ask the experts. Any thoughts? Like, is there a specific section of code that prohibits using a fitting like this? To me, it’s the same as solvent-welding pipe inside a fitting’s hub, except this one solvent-welds to the outside of the of the fitting’s hub.
Thanks in advance for any helpful comments.
