Love Your RV: Bad smell coming from under the RV sink?

From the bloggers at Love Your RV.

A few days ago I received an email from a follower of Love Your RV! named Larry. He wrote to pass along some information on RV sink plumbing that may be of interest, especially to those of you battling foul odors emanating from under the kitchen sink.

Larry has been trying to solve a bad smell beneath the sink himself and believes he has narrowed it down to a plumbing part called an Anti-Siphon Trap Vent Device (ASTVD). Yes, quite the mouth full, but actually a very simple little plumbing part.  Its job is to supply extra air venting to the sinks drainage system. Inside it has a spring attached to a round rubber flap which acts as a check valve allowing fresh air into the drain but blocking the smelly waste tank air from getting out.
