I'm stack venting a top floor bathroom. The 3" waste pipe comes up from a 4" waste in the cellar. The 3" waste comes up to the bathroom and 90's over about a foot where a wye and eighth goes up a wall and vtr's. The 3" run goes over and picks up the W.C and the tub which are about 5' away. I also have a lav that drains into the wye and eighth about 15" above, and above that a 2" vent that vents a kitchen sink on the 1st floor. The 2" vent for the kitchen sink ties in 6" above the lav. Does anyone see any problems with this setup?
