I have a leak on an outside pipe coming from the 90 degree elbow bend (I think). I have wrapped it in that hardening tape, but it still leaks (much less now). I would like to fix the leak completely, but here are my problems.
The pipe is right up against a wall, so getting around it is pretty hard. Below is a picture of the pipe. What about a 90 degree compression fitting? The problem with that sounds like i would need to cut the pipe with a pipe cutter and I wouldn't be able to do that seeing as the pipe is against a wall, right?
Does anyone have any other ideas? This is driving me crazy!

thanks... josh

How about chipping the wall around the pipe?

Thanks for the reply. I chipped away enough to get the tape around there, but that didn't fix it completly. I can chip away more, but I want to know what the best method of fixing this would be before i go chip away the whole thing!

by the way, i chipped away more wall and wrapped more tape than shown in the picture above.

to bad you just can't redo the piping...seems like a good time to.

Is it a water line, a drain, or what? How big is it? I don't remember seeing compression elbows meant for iron pipe. They do make straight unions. It wouldn't be elegant, but you could cut both pipes and put nipples in a new elbow, and connect both of them with compression fittings. You could remove the tape wrap and cut the lower pipe. Likely the other one would swing out a little from the wall, enough to cut it with a recip saw or a hacksaw. Compression fittings do not need a straight, smooth cut.

If it is a drain, I would be very tempted to try to find big enough plastic tubing to slip over it. A couple of hose clamps would complete the job.

This looks like a 3/4" water pipe. If this were my call I'd dig or break out a hole under the pipe on the floor and cut the bad piece out leaving the unthreaded end bare. If the elbo was good I would then remove the bad piece of pipe from the elbo.
I would then slip a dresser coupling over the bare end of the pipe and a threaded nipple,( after first taping the threads with teflon tape) into the elbo. You may then tighten both compression nuts on the dresser coupling for a solid connection.
If the elbo's bad I would cut the vertical pipe back to the nearest threaded fitting and convert to PVC using a male PVC adapter. You may then replace the pipe and elbo with PVC if cold and CPVC if hot and connect using the dresser coupling. Good luck, Tom
