After trying to locate a drip and tearing out 3 areas of wall, I finally discovered the source was a small nail hole in some PVC piping.

Is there a way to patch the pipe simply so that I don't have to cut out and rebuild the pipe?

It's a drain pipe for the upstairs bathroom.

Thank you!

There is the best way and there is other ways.

If its a small hole, if there is no other way to do it, you can buy a plastic screw, 1/4" long and put PVC glue and Cleaner on the screw and the hole, and screw it in. Since the screw is only 1/4 inch deep, it will not extend into the interior of the pipe, since PVC wall thickness is 1/4. To prepare the hole, drill it out with a bit that is exactly the diameter of the screw shaft without the threads.

My recommendation, though is if you can move the pipe at all, cut the pipe right at the screw hole and install a cupling. You can either buy a PVC coupling or a rubber coupling that you can install once you split the pipe. If you can cut all the way through the pipe and you can push one section to the side, you can install a fernco or mission coupling designed for plastic to plastic connections.

In order to install a PVC coupling, you would have to be able to move the pipe at least 1-1/2 lengthwise.

Good luck

Thanks. I couldn't do the coupling b/c the drain pipe goes right up to the drywall (no room). I did end up using a pvc epoxy filler that you apply with a syringe and then heat with a heat gun. I applied 2 layers. Then, as an extra precaution, wrapped the pipe in a rubber pipe tape (black, forget the name).

Hopefully the epoxy will do the job and the tape will ensure that.
