Black Tank Flush

[Boatman]

Can anyone tell me where the back flow preventer might be located on my 30.5 RLS? The black tank flush will not let water into the tank. Thanks.

Is is usually right at the spray head, the check valve is built in.

Probably not the back flow preventer, more than likely the flusher is plugged up with ( well you know what) mine was and i took the back flow out and still no flow. On mine it was located behind a storage drawer. Mine is a 07 314 bhds though. Good luck

Ours is located behind the lavatory sink, very close to the outside hose connection for the black tank flush.

Thanks for the replies. Hopefully it's not plugged with (you know what) as it is new and never has worked! Jayco customer service said it was in the wall behind the shower faucet. Do you think that would be hard to get to? I might just have to get by without it for awhile.
