In the midst of a half-bathroom reno and I’m trying to understand the current plumbing situation. Is this toilet properly vented? Link to diagram: https://imgur.com/gallery/RIRDCC5
I see the sink is tied in to this same vent, behind the toilet. This just doesn’t look the same as the venting diagrams I’ve found online. Also questioning everything harder because I found that a different toilet isn’t vented at all (not sure why, we can see a vent pipe from the attic that should be for that toilet).
