Very small leak on black tank when valve is closed

Valve was functioning properly, didn't move unit. Added a Cameo clear unit to backflush the black tank. Everything was normal, but now there's a small, but noticeable leak, where you can see the brown water, at the backflush valve.
When we release the water from the backflush valve, more brownish water is seen. When we open the black tank valve to clean out the tank, there's hardly any liquid in it. We've back flushed the tank 5 or 6 times and the solids come out.
We've back flushed from the Cameo unit, we've also tried to back flush from the tank flush that sends water inside the toilet.

My understanding of the cameo back flush (clear unit with hose connection) is you empty your tank then leaving the tank dump valve open you open the water supply to force water back into the tank and when it stops flowing into the tank you shut the water off and let drain. Myself I have never heard of a installed black tank flush sending water to the toilet are you talking about one that you insert into the toilet opening?

Thanks

Thanks for your reply there is a hose fitting in the storage compartment where all the flush pull levers are its labeled waste flush connection. We see the waste in the clear pipe camio when we shut the waste tank valve and are finished with the back flushing. You would think there should be nothing leaking since it was flushed out but after a few toilet uses we see that its leaking this was not an issue a few weeks ago and we have not moved the unit. Thanks Frank

You may have something solid stuck under the seat of the dump valve which will require you cleaning the seating area of the valve with a brush or something while the valve is open.

How do you find where the valve is?

Our plan was to fill the tank thru the toilet and let it sit for a few hours.

Not knowing what rig you have thats hard to answer. Usually the valve is where you pull the handle to dump the tank unless you have remote (via cable) operated valves. You might consider asking one of your neighbors or the park folks to walk you thru how to use the flush and dump and show you where the different valves are located.
