Black tank flush
 
Hello we just purchased a 2018 Cougar 32BHS. It has A Bath and a half and when it comes time to flush the black tanks I can only find One black tank flush. The one for the front tank. Where is the flush for the rear tank? I have two grey tank levers and two black tank levers. Any help would be appreciated.
Thanks

any chance the rear tank is piped into the front?

I don’t think so when I’m flushing the front nothing comes out the rear

When you say flush do you mean run fresh water to clean them or are you talking about dumping the black tanks. if dumping maybe the one doing nothing may be plugged.

Sorry reread your post I see you are definitely flushing the black tanks. You would think they would have separate hookups for the hoses. Dealer should know.

edit...ahh I missread, didnt realize you were looking for the rinse.

Welcome to the forum from SE Texas.

The dealer I purchased it from has no idea. It’s brand new so I would think it can’t be blocked or plugged

We camp next to a fella in Florida with a Heartland of some sort with two black tanks, one for each commode. His has only one black tank flush, in the full bath......and he also is not all that happy with that situation.

Did you ever find the problem? We just bought a 32bhs and both of my blank tank flush check valves were installed backwards. I still haven’t found my back black tank flush valve...

Black valves
 
Yea we finally found out one of our was installed backwards as well. The one for the rear bathroom but all is well now. Both black tank flush valves are in the hookup closet next to the right of the city water connection. Hope that helps if not ask anything else
