Hello everyone, I'm trying to install a sink in our laundry room. So far I was told by an "expert" @ Lowes that I don't need a separate vent for the sink. I attached a photo of the current plumbing. I want to add the sink 16" to the right of the 3"main drainage. Looks like a 1 1/2" vent pipe is intalled next to the washer drain before going to the main drain. Can I use a double san like the pic I attached 3" main with 2" sides? Any advise would be appreciated.
