Black tank flush

[jlbaker1962]

We have a 2022 Grsvity 3570. When I use the black tank flush on the rear tank I’m getting some water in the garage. Not al lot. My Question how do i access it

is there a shower or bath in the rear of the Gravity. There should be an access opening in a wall or cabinet. Sounds like the flush is leaking at a connection or the air admittance valve.

No only a toilet and a sink. I have looked all over for an opening and there is not. Will probably have to drop the chloroplast to get to it

check for a studor valve under the rear bath sink or if kitchen is on wall to garage check under that sink for a studor valve
