Hi

I just moved into a house and the waste pipe has a small leak. It appears someone tried to repair it with Silicon but obviously doesn't stick very well to PVC so it is leaking again. Normally I would just cutout pvc since it is not pressurized use a rubber coupler to replace leaking joint. However I'm not sure if that is the tool for this job as it is leaking right after an Elbow and the Elbow has a coupling for the pipe below it. Also since this is a vertical pipe will it possibly sag if I put rubber coupler in there. I guess I could make sure pipes above are attached somehow.

Thanks for any advice on best way to handle this. Pictures Below.

I wonder if they forgot to glue that joint. Since they did not use purple primer, it might have been easy for them to forget whether they had primed. I might consider this:

Take a small section out of the pipe below. See if you can pull that leaky pipe out. If you can, glue in a new piece, and patch between the two pieces with another piece of pipe and two banded couplers.

If the pipe does not come out with pulling etc, get a RamBit. Cut out the inside of the fitting. Put in new pipe and use two banded couplings.

Make sure the pipes are supported above before cutting.

I am not a plumber.

In the question, you mentioned using a rubber coupling. Please note that the coupling you describe is not allowed in above ground applications. If you do go this route, then the coupling you should use is a band coupling. This has bands over the entire length of the sleeve, not just the ends. Replacement would be my suggestion as patching a leak in a PVC joint is usually not too successful and will take almost as much time as replacing. Well, that may be a bit over stated.
