Replace Cast Drain Line

3 Replies

Hello BP. I am working on my first flip. I have tried calling 6 plumbers in the area over the course of two weeks and only one of them has called back/answered the phone. I've come to the conclusion that I am going to do the plumbing myself.

That being said, I have the main sewer line coming up out of the floor in the basement. It then goes into a PVC Y pipe and then back into a cast drain/vent pipe. I'm wanting all new drain lines. Should I replace every from the roof vent down with PVC or should I try to salvage the cast pipe? Any and all input is appreciated. Thank you!

@Dalton Dellinger obviously replacing the cast pipe is the best solution. But not entirely necessary if the cast pipe is in good shape and doing it yourself without experience can be tricky too. I’ve just come across one in a rental property I recently purchased and we are tearing it all out, but the house is 120 years old so it has served its purpose. Hardest part will probably be tearing the old cast pipe out. New pvc should be relatively easy to put in.

It has a full basement and the bathroom and kitchen share plumbing on the same wall. I'm worried about putting the new vent up through the roof but I will do tons of research! Thanks

Why dont you just replace what you can easily access for now. The stuff that's hard to access I would hold off on doing If it's in good shape.
