Dont know about that valve but I have had sewer smell come in if I have any roof vent open, coming from my black water vent pipe on the roof. Happy Camping!Does anyone know the location of this valve. It's not under the bathroom sink. We're getting a sewer smell in the heat of the day.
Thanks in advance.
Leaving your black tank open all the time will lead to the dreaded poo pyramid!Have you placed your sewer hose in a position that'll Make a "P" trap, due to the sewer hose open to the sewer system, the smell could be from that
