View Full Version : Pipe Sweating or Leak?

Good evening. I have a small damp spot between my second floor and the first. The general location is where the toilet water supply comes into the bathroom. I have not cut the sheetrock back yet.
House is over 38 years old and probably needs to be replumbed - just not an expense and mess I am prepared for at this time.
Has anyone had experience with 'relining' their piping?
Thanks
Tim

The only things I've seen (and there's probably a lot I haven't!) are drain pipes, and then relatively straight ones where you may not want to dig it up because of a big shade tree or something like that. If you pipes are galvanized, forget it.
In an enclosed space, unless there are huge air leaks, it can't be condensation...you have to have wet air moving over a cold surface for condensation. Between the floors, possible, but not likely. Probably a leak. Water will run a long ways, so it may not even be in that area.

Are you sure it's not your toilet that's leaking? Flush it a few times and look to see if that water spot gets any bigger.
Pull and reset the toilet and see if the wet spot drys up.
Do this B 4 cutting the ceiling.
What is your piping material. Water pipe relining is "voodoo science" because you have to use faith to assume that the cleaning process removed all obstructions, and the relining epoxy contacted and bonded to the entire water system piping. Both of which are essential to a proper repair, and neither of which can be verified.
