Richard,

Yes in ah bay. That drain pipe appears to be coming from either the sink or d/w It is a mystery to me so far. I put in an email to the guys at newell in hopes of having some light shed on this setup. it looks like gray water could flow down and into the main drain because it enters the discharge pipe after the gate valve. there are two gate valves on the curb side, one wraps around to the driver side like normal and the other is directed to the curb side and then the mystery gate valve in the pic.
