I would like to add a clothes washer drain to an existing cellar bath room drain per Maine UPC. The bath room is currently plumbed under the cement floor with a 3” wet vent serving a toilet, shower stall and a lavatory sink, the 3” drain runs into a sump which is vented with a 2” vent line and is near the outlet to the septic tank. The sump pumps above the septic tank outlet and gravity drains from there.
I have attached a schematic which shows the original bath plumbing with the proposed Washer standpipe plumbed into the 2” sink drain using a 2” double sanitary tee with an additional vent line from the sump installed in the bathroom ceiling. The washer hookup would extend 2 1/2ft in the bath wall and come out in the adjacent laundry room with a 2” ptrap and standpipe.
Is this correct?
What is the minimum vent pipe diameter for vent to be installed in the ceiling?
Thank You
Thanks
