Why is it stinky in my RV even after I dump black/grey tanks?

Have you flushed the black tank recently?

Added chemicals to black and grey tanks?

Do you leave the valves closed in between dumping sessions?

You could have a AAV (Air Admittance Valve) gone bad and needs replaced, see other docs here about AAV, the explanation and how to replace it(coming soon)
