I have a small leak at a glued connection of two pvc plumbing pipes that are
located horizontally under my kitchen sink. I would like to stop the leak
without having to take apart the pipes,etc,etc.
Any suggestions(plumbers goop,etc) on how to successfully do this would be
Plumbing though, does mean a lot of things, such as drains and supply lines
You may get away with some sealer on a drain, but not on a supply
Sometimes you just have to do the job right. Anything less may result in a
worse leak that usually happens when you are away for the weekend.
Agreed, ONLY on drain. I've tossed 100% silicone on tiny ones absolutely
making sure the drain did not get used overnight. Then, on black pipe, a
dab of roofing cement has worked :-) This is cheating with a hack twist.
Good point. I had assumed it was a pressure pipe, but it may not be.
As for those who have suggested methods to fix a pressure pipe, I would
not trust one inside a wall or anywhere a leak would be a problem. It is
just too easy to replace it properly.
PVC pipe is glued with a solvent that actually dissolves the surface. If
the leak is small and you can get it dry, you might try putting some primer
and glue around the joint. I haven't tried this and would probably not do
it myself (fearing that it will just make it worse), but it is worth a try
if you can't cut it out.
I had the same problem with a toilet drain under the 1st floor and in
the basement. I found that Home Depot carries a special black plumbers
tape ... it looks like electrical tape, that stretches and adheres to
I dried the pipe thoroughly, then wrapped the pipe tightly with all
the tape on the spool, about 6' of it. That was 3 months ago. So far,
it's still dry. But I don't know if this is a long-term solution.
I tried silicone sealer first, but the water seemed to leak under it
and I had to pull it all off. So I wouldn't recommend that route.
