Install Utility Sink into current washer standpipe/vent
I am looking to find a solution to the correct way that I can plumb this utility sink into my current washer standpipe/vent. I live in Maryland.
I have a attached a picture of the current setup. Standpipe on right going to drain/vent. I would like to bring in the sink from the left side of the set up. Can I replace the san tee with a double san tee and have the sink and washer share the same vent since they are draining at the same level? Or will I have to vent the sink side along its horizontal run and run a vent up and over to the current vent?
The sink will also be in my garage which is 18" below the laundry room so I will have a utility pump pumping the water up to the drain.
