How to use the same drain.vent for utility sink in laundry room?
I want to install a utility sink in my laundry room utilizing the same drain/vent as what the washing machine uses now.
Current setup: Washing machine enters into a drain, goes through a p-trap, then that connects to the drain/vent pipe from the left side.
What I want to do: I want to install a sink on the left side also and run the drain along side the drywall and turn it 180 degrees and enter the same drain/vent used for the washing machine from the right side. I figured turning a pipe 180 degrees isn't a problem, so long as I have enough slope in the drain pipe.
Problem: In a perfect world, I would be able to use a double Y connection on the drain/vent (one for the washer and one for the dryer), however, the current connection for the washer is to high on the vent, so I would need to bring the utility sinks connection below the connection of the washer on that same drain/vent. Does this cause a "venting issue"? Any other ideas? Thanks!
