Tom,

CPVC you can flex enough to gain some clearance, but 3" pipe, unlikely.

I don't have a clear picture of what you've got, but you mention a drop from a closet flange. If the piece you're looking to replace connects (unbranched) to your toilet, I'd pull the toilet, then repipe from your leak to a new closet flange.

If this doesn't help or won't work, try posting a picture of your dilemma so we can get a better look. We'll be watching...

: Can you offer any other way to splice into an existing albeit old 3" line? Should I risk making existing piping bend for that moment that I need to make up that slack?

: Thanks so much for your help,

: : Troubled Tom,

: : I've used the rubber couplings of which you speak, although my rule is only to use them where access is always available (although sometimes difficult) for servicing/inspection. Personally, I just don't trust them completely.

: : On the flip side of that, though, I'm currently witnessing large commercial buildings go up that use hords of these couplings (mission style - with the metal bands around the rubber inner). Some codes allow similar couplings to be buried. But, if you don't mind running the risk of redoing some drywall down the road, it could work well enough, they're just not as permanent or "comforting" as a glued joint, which is always preferred. Good Luck. Greg

: : : I posted a few days before Christmas about a leaking joint that wiped out some drywall in my kitchen before a party. You suggested (as I figured I needed to) that I replace. Here's my question:
: : : How good are flexible drain couplings? I am going to have to insert about 6 linear feet into my second floor drain line including a drop from a closet flange. To make a solid connection on each end will require me to couple one end into existing 3" pipe near another fitting and work my way to the other. To do it right, I will have about a 1" overlap to make sure it makes up solid if I use a typical coupling. You and I both know I can't bend 3" pipe enough to make that up. I also am sure that if I try to move existing plumbing that 1" to get it right, something will give...I just feel it. I found a rubber "flexible coupling" made by PlumbQwik I think that promises permanent coupling. Is this the answer or do you have a better suggestion?

: : : Thanks in advance!
