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.
