Hole in Vent Stack

[petermedhurst]

I have started a bathroom reno and when I pulled the old shower out, the wye (tee?) where it connects to the vent stack broke. It's an 1-1/2" drain from the shower to a 4" vent stack. So I effectively have a 1-1/2" hole in my vent stack right now with a rag stuffed in it until I can come up with a solution.

I'm replacing the shower with a bathtub which will drain through another pipe, so there will be no pressure where the hole is and I would prefer to fix/patch it, rather than cut it out and replace the whole thing, because it is going to be extremely hard to get in there to work.

Is there a product or method for fixing the hole that will safely keep the fumes out of the house?

Thanks for your help.

You have to cut out and replace the broken section.
