black tank flush check valve

[Rarthur78]

I think Mine is leaking and I think it is located near the shower somewhere.
How do you get to this check valve?

I have water leaking every time I flush out the black water tank. I have a 2021 North Point 377 RLBH and the leak always comes through the drawers in the wall of the Mid Bunk Room

sounds like the vacuum break...not the check valve located where the water hose attaches.

Should be behind a removable panel near where you are seeing the water leak.

Some have replaced them with a check valve. If mine gives me problems, I’ll just remove it and straight pipe it.

That is what I did on my old trailer when it started leaking. I also, added a screw in shutoff valve where the hose attaches. I would turn the added shutoff valve off first when through rinsing black tank, then turn the hose bib off before disconnecting. No chance of any back flow turning the added valve off first while under pressure.

This is my first camper with a factory built in Black tank flush. I followed several other members here and proactively removed the "going to leak" vacuum breaker and simply replaced the hose fitting in the side of the camper with a duplicate of the city water Inlet that has a built in check valve. I didn't want to wait for the inevitable black tank flush leak.

I quick cut of the pex, sharkbite fittings makes it a quick and easy job.
