In my 61 bungalow the main pipe goes out to the septic has a hole near the bottom. Its copper all of this and heavy then goes into a massive pipe through the wall. Friend said the pipe will be sealed with Rope. Its not it looks to be lead. I cant this type of plumbing stuff at Box stores and same friend said for now just use Epoxy and repair it temp. I got JB weld and some fiberglass around here and did a repair. The JB weld was in a dual tube and it was the worst one ive ever used, push it nothing comes out one side, use it again and tons out one side little out the other, pop sound air comes out and and.
I had tried to find two tubes stuff as I trust myself to mix, most dual things ive used worked pretty well, Looked for Epoxy could not find it this stuff did not say epoxy on the package.
The JB never cured properly its rubbery in some spots. I see a slow leak starting so will rip it off clean and start again.
Should I not be able to get epoxy and maybe some filler in it I have that talc and glass ball stuff and use my fiberglass matt not the woven stuff? Other things the focus now. I figure the copper you clean it really well with alcohol or lac reducer and as long as the epoxy sets should get a good repair for some time. the JB stayed like Rubber in part of this hole size is about 1/2" x 1/2" once I pushed and mangled it larger to get to thick material.
