Hello --
Quick question about adding some additional drain (DWV) lines in my basement floor.
Currently, I have a 4" CI running horizontally through the center of the basement slab. It runs from one end of the house to the other, where it exits to the outside. The slope is a generous 1/4" per foot and cleanouts are properly spaced.
I would like to add two powder rooms in the basement which would be located equally perpendicular on either side of the 4". I would prefer to use a Double Long Turn Combination Tee-Wye that I splice into the existing 4". I can then branch out both ways and connect the other fixtures.
Not asking about venting as this will not be a problem and will be done correctly (separate dry vents to roof line -- not wet vent to vertical stack going upstairs.)
I figure a regular Double T would not be appropriate, but the Long Turn Combi looked like a good solution. I thought this would be better than splicing in two separate combi's (one for each powder room). I would continue 4" to each powder room as they make the 4X4X4X4 double.
Any problems with this plan using the Double Long Turn Combination Tee-Wye in a horizontal position? I would prefer this over using two single Combination Tee-Wye's. I know a standard Double Sanitary Tee would be a no-no as it would not route the waste downstream as efficiently as the Double Long Turn Combination Tee-Wye.
Appreciate the feedback.
