I am working on my basement bathroom, and very new to this stuff, but i'm stuck thinking about the venting options for the tub. I have a couple questions and I've attached a quick drawing of what I have.
1. Is the tub line already vented perhaps along with the toilet stubout, or not?
2. Can i tie the wetbar drain into the same drain as the vanity? I have the wetbar sink venting with an AAV which is permitted in my area, so I don't need to worry about venting that.
3. If the 2" line under the concrete does need its own vent, how can I tie into the 1.5" vent stack that's there? The wetbar drain line in in the 2x4 wall, so I can't go around it and up into the vent line?
Or perhaps I should drain the wetbar line and the tub both into the 2" tub drain and that will clear a path to get to the vent? Any thought would be appreciated. Thanks in advance,
