Hey all, I want to add a laundry sink to our utility room. I was planning on tapping into the existing plumbing for the washing machine. The utility room shares a wall with the garage so I went ahead and opened up the wall from the garage side to see what it all looked like. I found that the washing machine drain pipe has no trap visible (maybe below the slab?), and no vent. I hopped up in the attic and verified no vent pipes anywhere above the utility room. The house was built in 1987 and I am in the Dallas/Fort Worth area. My question is- what do I do to add the sink? I want to put the sink in the area denoted by the red box. Do I need to go ahead and add a vent and a trap to the existing washing machine drain pipe and then add the laundry sink plumbing to that? Are there any other foreseeable issues? Any and all comments are appreciated. Thank you!
