Apparently, she tried hanging a toilet paper holder in the 1st floor powder room and had trouble geting the screw in, so she patched the hole in the drywall and moved it over several inches.
I noticed a slight dampness around the patch and cut it open and found the hole in the pipe. The damage wasn't too bad - a few inch square piece of drywall over a few years of the hole being there, so it can't be leaking much.
Anyway, is there a way to fix this hole without cutting out the section of the pipe and coupling in a new piece? Doing that would require removing much more drywall, which I don't want to do if I don't have to.
Is there anything that can be used to fill the hole or wrap the pipe?
