Two questions. If I’m using 3” for toilet run and 3” vent run, what is the longest run trap to vent for that toilet? 2nd question. Can a lavatory 2.5” run into the 3” toilet run before it connects to wet vent? I have tried to outline this in the diagram. Appreciate all the help, this has me...

I'm planning on tacking a bathroom remodel and would like some pro advice as to whether this is up to snuff or not. I've never done wet venting before, but apparently that is what used to be in the bathroom and I'm planning on slightly modifying. Originally there was a double vanity (on the...
