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
