Need washer & sink plumbing setup advice.
I have been searching high and low for info on how to setup plumbing for a washer and sink and finally found this drawing on this site. The diagram is close to what I need except my sink is on the left side and the washer is on the right.
Base on this diagram, can I run the sink drain below the washer drain or run the washer drain directly to the vent and add a new vent above 42" to the sink drain instead? Reason for asking is to avoid cutting too many holes on the wall stubs.
