Hey Folks, We had a sewage gas leak, so I pulled of the toilet and opened things up. Here you see the toilet vent cracked, which goes back into the wall and up (the sewage line goes down). It is very tempting to just replace the cracked section with ABS, and then stitch it all back up. We could also pull out that entire vent going up, but it seems like overkill. I guess the benefit would be to replace it with something that weighs less. Another idea is we do tons more excavation and replace everything. What are thoughts here? For a little more background, all the sewage lines Out of the house are pvc, which we put in 10 years ago. Thanks Folks!
