I have a 01/24 delta 321bh. The water valve for the black tank flush does not spray water. I cannot find the valve. Not under sinks. They are in the center of trailer. Where is it and how do I get to it?
water valve for the black tank flush

Make sure the check valve is not depressed. Remove the screen on the hose connection area and push on the valve. If it pops out...you're back in bsuiness.

Would you be referring to the black tank shower head? It would be located on the black tank itself.
Access would be from underneath the RV meaning you will likely have to drop the underbelly.
Apologies if I have misunderstood your question.

This might help you as well, I guess the “easy button” would involve following the white PEX until you find what you are looking for.

Thanks for the responses. The other TT the valves access is under the sink. Is there access by removing the drawer under oven? Maybe removing the electrical panel’s?

Unfortunately, I can’t answer that question.
Delta owner’s might have to chime in on this one.
I would suggest you place a call to Alliance Service and see if they provided an internal access panel somewhere.

Delta 321bh owners. I tried calling service with no help. Does anyone know where the access panel is for the black tank flush valve on the delta 321bh or how to access?
I don't really know what you're asking for. To connect and use the black tank flush, you simply connect a hose to the connector in your water area (by the fresh water fill)
Are you asking for something other than how to use the blank tank rinse?

There is a one way valve to prevent backflow. Mine is not letting water flow and needs to be serviced. I cannot find it. It is usually under sinks but in the 321bh the sinks are in the middle. The valve is not there. Where can I find it and how do I access?

I would think the valve you are talking about would be immediately behind the connection for the hose.

Not much help. Everything is covered up. Where? Under the shower? Access where?

Sorry it's not much help. Perhaps I don't understand, the shower and sinks drain into gray tanks so I don't understand why a one-way flush valve for a black tank would be in that area. As Jim states the hookup for the black tank flush is a black female hose fitting next to the white potable water connection on the water panel, my guess is the flush valve is located close to that hookup point behind the water panel. Our water panel is accessed by raising the basement door and access to the back of the panel is a removable panel directly adjacent to the panel. I hope this helps you find the black tank one-way flush valve.
the check valve is right behind the screen on this inlet

Will this previous post from Jim B. Help you?
Doesn’t answer your location or access question but shows basic components. If your looking for more than the check valve that could be installed directly behind the inlet screen, your just going to have to follow the white PEX tubing to track down what your looking for. As I stated before, I doubt anyone provided access panels from inside, so it could be an adventure into the underbelly.
Top Left item: Plastic Water Inlet Valve( would be black for a rinse system) – located in Nautilus Panel – manufactured by B&B Molders
Top Right item: Atmospheric Vacuum Breaker (AVB) or Back Flow Preventer: located (typically) in bathroom in base vanity cabinet or in/near laundry plumbing area (usually high mounted)
Bottom item: Tank Sprayer – located on end wall of black tank(s) near top
We typically use white PEX pipe to plumb this system. So that's white PEX pipe from the back of the Water Inlet Valve, to the input side of the AVB, then from the output side of the ABV to the Tank Sprayer input at the tank. If you have more than 1 black tank, you'll likely have more than 1 of these systems and AVB will likely be co-located.

Tku. An adventure I hope I do not have to take to much apart.
