2019 Cougar Tank Flush

Good Evening,
Just picked up my new 2019 Cougar Half ton 32 BHS a couple days ago. I seem to be playing phone tag with dealer and am hoping maybe someone here can help.
In the outdoor shower area I have four hose hookups,
- first one is for winterizing,
-Second one is for city water connection
- Third one i am questioning, I was thinking possibly the rear black tank flush?? Any thought as the when I turn the water on it dead ends?
- Fourth one is for the front black tank flush, found this out after flooding the upper bathroom due to loose connections and finding check valve installed backwards.

FYI, I do have a gravity feed fresh water fill, If any one knows about the third hook-up and could shed some light on it, I would really appreciate it. If it is the rear black tank flush, is there another check valve that could be installed backwards also and where would that be?


Thank you

You are correct. It is the black tank flush.

Thank you, do you know if there would be another check valve for that one or why the water is dead ending and not getting to rear tank?

It sure sounds like the check valve is installed backwards. That seems to be a common occurrence based on the number of Forum posts about black tank flush systems. The black tank flush on our old Laredo (TT) seemed to dead-end too, turned out the check valve installed backwards (but was fixed under warranty).
The check valve in our current Premier (TT) is under the bathroom sink but it leaked when first used even though the dealer said they verified it worked.
Evidently even though it leaked, it worked??

Hope this helps.
