I've been living in a fixer-upper for a while... I've been fixing a lot that was previously done wrong.
I've finally gotten around to ripping out our first floor bathroom (two full bathrooms) and I'm noticing some plumbing issues. Mainly that there's what seems to be a vent pipe terminating into my wall. So yeah, there are no proper plumbing vents in this house. Surprisingly I haven't yet had any problems, but now that I've got a bathroom torn out it seems like I should fix it correctly.
I've made a diagram of the existing... situation. The large pipe is 4" PVC, and the smaller pipes are 2" PVC — I don't have wall access into the second floor bathroom at this point, but from what I can tell by the first floor, everything is converging into a single 4" pipe.
I also put together what I'd guess a solution might look like (the vent pipes in yellow). The diagram is a bit rough, but is this in the right ballpark?
Could I alternatively vent out through the second floor roof and add an AAV to the first floor sink? (I can have one AAV according to local code)
