I’m running a new vent out of a second-floor bathroom remodel and just did some exploratory destruction in a finished attic.
The original plan was to punch a new hole through the roof for the new PVC venting, but I found that the main cast iron vent stack goes through the roof directly over the bathroom. I’m now wondering if I could just tie into the cast iron with a Fernco saddle?
The other option, of course is to cut the cast iron out at the attic level and run all new PVC up and out, but that sounds like more work than necessary?
