Can cracked PVC be repaired?

[JimK]

I have never had any putty epoxy last in a pressure side leak.

I have found only one product that works to repair PVC and stands up well to pressure side leaks. It is called Plast-aid. I have used it successfully several times now and have not had it fail but it does take a bit of practice to get used to. It cures in about 15 minutes to repairs are fast.

Their website has some excellent demo videos of how to use it.
The nice thing about it is that you can apply it as a glue or a putty so it can fill a crack. My only advice is use it outdoors if possible since the smell is really strong until it cures.

Thanks. I'll check that out.

I also did a Google search and found this:

3M 08101 Structural Adhesive worked for me for PVC pressure piping. It's urethane, not epoxy. In shear adhesion test with rigid PVC,
the PVC breaks before the adhesive bond (2000 PSI).
For even more strength, fiberglass cloth can be embedded in the patch. I patched our sand filter base which was broken into 3 pieces and used fiberglass mat for reinforcing.

Wear disposable gloves, and plan your application, because it sets rapidly.
