Greetings. I've done some looking around but can't find recommendations on my specific issue - what is the best way to connect a sink and clothes washer to an existing 3" drain. I've attached a quick drawing, which does not have accurate pipe sizes and fittings, but shows the general layout. I would like to tee off the existing 3" drain pipe with a 2" run, that will tee off to the sink, then to the clothes washer. I have three choices for the vent line - 1) between the the two p-traps as shown on the drawing, 2) between the 3" pipe and the sink connection, or 3) both places. Any suggestions?
