I'm remodeling my house (single-story ranch) and now fixtures are much further away from the original main stack. The main stack is on the backside of the house, the sewer line comes up the side and around the back of the house.
I want to avoid running 3" waste lines horizontally down the side of the foundation walls in the basement since they would cross my basement windows. Instead I was planning on adding another stack near the master bath, cutting thru the foundation and teeing into the sewer line.
To the Original stack I plan on connecting the kitchen sink/dishwasher, washing machine (basement) and double vanity (from master bath). To the Proposed 2nd stack I plan on connecting the shower, tub and toilet. The reason for running the double vanity line to the original stack is that I want to keep it up in the floor joists, but I could also run it to the proposed 2nd stack.
For the master bath, the plan is to have a 3" waste stack and 3" vent thru roof. To the 3" waste stack would connect the toilet drain and a 2" horizontal drain line serving the tub and shower.
Toilet drain: flange (3")>long 90>straight>long 90>wye fitting on main stack
Shower drain: flange (2")>p-trap>wye>2" horizontal drain... a few feet down the horizontal drain line a sanitee (on its back) to serve as 1.5" vent>3" main stack vent
Tub drain: drain assembly(1.5")>p-trap>straight>45 elbow>wye>2" horizontal drain... a few feet down the horizontal drain line a sanitee (on its back) to serve as 1.5" vent>3" main stack vent
Horizontal drain line: wye on end w/ cleanout and tied to main stack via sanitee (3x3x2)
Thoughts? Is it kosher?
