It's been years since I've needed to post here, but my luck has run out.
I was chasing down a sewer odor in the c.1950 part of our house. The basement is finished, so the stack was behind drywall. I assumed it was all original cast iron, and was hopeful the problem would be in the basement section and I could replace that portion with PVC. Well, when they did the basement work, they redid that portion to just below the subfloor.
The only thing that enters the stack above the floor is the bathroom lav. I turned that on, and quickly found the problem. As you probably guessed, the original cast iron has failed with a nice split and a hole big enough to put a finger in.
Since some wall opening will be required in the bathroom now, I'm trying to figure out how far things should go. Should I support the CI, cut out the bad section, and splice in PVC, or should the entire remainder of the stack be replaced all the way through the roof? It's a single story and only a few feet in from the edge of the roof. Part of me thinks the bad part has gone bad because of water from the sink, and that the section above will still be good. The other part says it's all 70 years old and the rest may develop a crack or holes soon.
If just the bad part should go, I should be able to DIY it, but if the consensus is that it should all go, I think I'd bring in a pro.
