Cracked/Crumbled tub drain pipe, best way to repair.
House built in the 50's, and the original drain pipe from the 1st floor tub extends about 12" down into the garage below. This pipe has cracked/crumbled right at the elbow (has a small bend that looks like a 5" trap) before running horizontal with the garage ceiling.
What is the best way to fix this. Would I have to rip open the ceiling. The ceiling appears to be cement, but I am not sure.
Can I just cut above the inch wide crack that is near the threads, and also make a cut on the horizontal pipe, and just put some sort of rubber boot (sorry not sure about terminology), on it to fix the leak. I'm afraid that tightening the boot may crack the pipe, since it appears weak.
Should I just wrap the pipe, or use some type of epoxy to seal the leak, do they make such a product?
Thanks for any help. Wife is upset that the kids don't have a tub/shower, so I might just call a plumber in, and get it fixed! I figure I can fend her off for a couple of days though :)
