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 that section with ABS, and then stitch it all back up. Alternatively 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!
