black tank flush hook up

Is there a proper name for the connection for the black tank flush connection. Mine is spraying every where on the back side of the fitting. I cant seem to find the same one on the net anywhere . It looks the same as the city water hook up. Iam assuming there is a back check valve in it.

The check valve is located in the anti-siphon device, usually located inside the bathroom sink cabinet. It looks like this:

Double check that the hose washer didn't fall out of the flush connection. I've had that happen and thought it was the connection when it was the lack of a hose washer in the connection.
