I'm working on a remodel and need some advice on venting two sinks and a washer. Location is Kentucky.
I would like to avoid adding any additional venting to the roof and I'm hoping to be able to tie into an existing 3" stack. The biggest hurdle would be turning around two corners, but I think I can make it work. Would the layout in the attached photo work if I slope the vent lines 1/4" per foot? A few notes/questions about the photo:
1) I would use a 3" x 3" x 1-1/2" x 1-1/2" Hub PVC Double Sanitary Tee. I think the one in the photo is upside down. I will rotate it 180 degrees so the flow is correct.
2) Is running 1-1/4" vent lines acceptable or would they need to be 1-1/2"? I would change the sanitary tee on the washer vent to transition to 1-1/2" or 1-1/4". I would prefer to run 1-1/4" vent lines because it would be easier to run around the pex lines used for the shower next to the washer box.
3) I plan to reroute the switch box to accommodate the vents.
4) The distance between the washer box and the trap is a little over 24". As you can see, I'll need to offset the drain to reach the trap. From my understanding, the washer drain needs to be 18" minimum. Is that 18" measurement the straight pipe at the washer box or the total length of the drain including the 45's, which would be around 24"?
5) This is a single-story room and there is no attic space above this room.
Thanks in advance for the help and advice!
