Drain/Venting.

I have two questions reference my picture. This is in the laundry room of my house. the drain coming in from the right is from a wet bar in the family room. Is this vented propery. The second question is what would be the best way to attatch a utility sink drain. If i attatched it to the vertical drain would i need to also connect it to the vent? The base of the stack as well as the ptrap for the washer are all cast iron. I am not exatly sure what all is conected to this branch of the vent, and without tearing out all of my drywall i wont know. Basement was remodled when i bought the home. Thanks, paul

Which vertical pipe are you wanting to attach the utility sink drain? What size are the pipes?

The vent is 1 1/2 and the drain is 2in. It doesnt matter wich pipe as far as attatching the sink to. It will sit about 4 feet from either pipe, they are right next to each other. Can i just tee into either of the lines?
