Black water stinks both inside motor-coach & outside

[Teetalow]

My 2015 Tuscany black water stinks both inside & outside when empty. Also when I flush the black water tank with water from the hose, I get water inside coach. Any thoughts?

Perhaps the AAV under the bathroom sink has stopped functioning...

TY. I will have to look up what that is. Also, when I flush my black water tank with a hose, I get water inside the bathroom. Any idea?

If you are referencing a San-T-Flush system: there's obviously a loose connection under there...
FDon't use it until the leaking is stopped.
Good luck!

Check your vacuum break (backflow preventer) in your San-T-Flush system. I had one stick in a Grand Design trailer and it flooded my bathroom. That could also be the source of the stink. They have a flimsy spring which compresses when you apply water pressure to it. Just a thought...
They're usually found above the black tank somewhere... usually behind a removable access panel.
