Black tank flush

Have a Wolf pack toyhauler, 2 questions.
1. When I hook up the hose to flush the black tank, nothing happens, no water flow into system or out of the drain hose.

2. I have two toilets, is there a seperate flush hook up for each toilet, the one I found is located by the front toilet?

It’s usually the backflow preventer causing the issue. If you search the forum (too right of the web page) for black tank flush or black tank backflow, you’ll get a host of threads on it.
