Hello,
We are currently in the process of adding a laundry sink to a new wall of cabinets. The issue that I am having is where the sink is going to be there seems to be no easy way to tie into the drain stack to the right.
Because of where the washer and dryer need to go, those cabinets by the stack are just shallow and not large enough for a sink.
The plan is to tie into the drain stack shown in the picture from the upstairs washroom with a 3x3x1 1/2" san tee, and then branch off the vent with a wye. The vent will go up and tie into the existing vent from the washing machine in the ceiling and then out the roof.
I would then bring the 1 1/2" pipe out beside the 2 heating ducts at the edge of the shallow cabinet with a long sweep 90 (I could also. This is the cabinet where the trap would be and then the trap arm would feed left into the sink cabinet to connect to the sink,
Is there any issue with this plan?
The only other option is to run the drain in the same wall as the copper pipes but then I need to break into a wall in the basement to tie into the stack there. I would then have no way to tie into the vent from the laundry as those heating ducts also run between the joists where the vent would need to go. Right where I need to tie in is an expansion joint so that would create another headache for me that is larger than I can likely manage.
Appreciate any feedback that's out there.
