I want to add a washer drain onto and existing plumbing in my kitchen but don't want to run it inside the sink.
On the next side of my kitchen wall is a full bath and the sink inside runs on the same plumbing,but the kitchen sink branches of first.
Should I run the washer off the end where the bath sink forms a 90 degree or sightly above from the main vent pipe.
Hope this is clear enough.
