drain line question

[wayne.yl]

while reinstallling the shower pan on my 77 sovereign, I inadvertantly drilled a rivet hole through the shower wall and into the drain lline just behind the wall and between the the stove. My question is, can I repair the drain line with a polyurathane patch or something other than cutting the whole drain line section out. I do not want to remove the shower wall between the shower and galley, I will have to if I cannot patch the small hole. any advice welcome.
Thanks,
Wayne

are you sure this isn't a vent line? "between the stove" sounds like it's vertical. If not, try some plastic weld (even if it is!). It worked on my water inlet fixture for the fresh tank. You can find it with the expoxies in the paint department at Home Depot.

If you have space you can also get a rubber pipe splice, slice it so you can wrap it around the pipe, then clamp at both ends. You may want to put some vulkem or other suitable caulk inside. When that cures I don't see how it could leak.

Thanks for the advice
This sounds very encouraging and quick as I am near the end of my rope in repairing and replacing the shower pan already. The job has become way more than what I first expected. By the way, it is a drain line behind that shower wall, it makes a bend behind the stove and runs horizontal along the shower wall and then drops vertical to connect with the shower drain.
I will take your advice and see if can get it fixed.

hi- at least it's only a drain line, with no pressure on it. If it is that black pvc stuff, I would think you could just goop some pvc cement on it, or a small patch with the cement gooped on it. Should be a piece of cake- no worries.

Hi wayne.yl--Use a sheet metal screw, slightly larger in dia. than the hole, with a little cement or caluking on the threads. Screw the screw in to cut in the threads. Remove the screw and trim off the end so the screw thread is a little longer than the pipe wall thickness. Goop the threads with cement, or caulk and replace.--Frank S
