I am adding a half bath on the first floor and a 3/4 bath on the second. They are stacked above and below each other. It will be all new plumbing on the left side branch of my drawing. Do you see any problems with my venting of the two baths together using a 3" stack? What fittings are necessary for the connections on each floor?
Horizontal distance from new stack (on the left) to main(original) CI stack where I will tie in is about 7feet. The new WC on the second floor will be about 3feet from the new stack so horizontal distance will be right around 10 feet total after all the drop.
Long sweep at bottom of new stack with cleanout wye above?
Sinks=1 1/2", shower 2" and "3 inch for stack and WC to the basement.
