Hello all, I have a 2004 3685FL and there is a bad odor, not sewer, coming from under the bathroom sink inside the cabinet. I checked the drain fittings and all are tight when I noticed a pipe with what seems to be a vent on the end connected to the sink drain after the trap inside the cabinet. Is this some sort of vacuum breaker? Grey tank empties no problem, sink and shower drains okay.

Any ideas?

Thanks in advance,

George
