Hey all,
I'm new to posting on the forum but have been following for a couple of years while I've been remodeling my house. I'm about to start on a second floor bathroom and was hoping for some specific feedback and advice. I've demoed the existing plumbing (which was inadequately vented) and I'm adding a wall hung toilet along with the proposed plumbing. The only existing/remaining plumbing is the 3" drain and the lavatory plumbing with 2" vent which are shown on the diagram in red. The situation is tough in that there is limited space in the trusses between floors as well as a header for a first floor window. Consequently, I think the best solution is to tie the tub and toilet together and add another vent that would tie into the existing 2" vent above the lavatory. Also, due to space the lavatory needs to be tied into the main drain below the truss space and in the first floor wall.
My specific questions are...
Any other thoughts or anything I'm missing? Thanks for your help!
Terry

My specific questions are...
- Does the attached plumbing diagram adequately and correctly drain/vent the fixtures?
- Does a sanitary double wye work for tying the tub, toilet, and vent together? (It should be noted that the distance between the vent and both tub and toilet is less than 2')
- Are the line sizes appropriate? Specifically, is the vent size adequate? The current vent for the whole bathroom is 2" but could be upsized if necessary.
- Also on that note. I will be doing the second bathroom after which is the same except a 1.5" vent from the kitchen sink ties into the this bathroom's 2" vent. Is that 2" vent adequate for tub, toilet, lav, and kitchen sink?
Any other thoughts or anything I'm missing? Thanks for your help!
