Kevin -
One way to find out if that is the culprit, is to connect a hose to the black tank flush and turn it on. Best to have two people do this - one to operate the tap at the hose and the other to watch for any water leaking or coming out of that vacuum breaker. Keep lots of towels handy to wipe up any water.

The minute you see water coming out, get your partner to immediately shut off the tap.

Not very scientific, but you will know for sure if that is where the water is coming from and that is the source of the problem.
