Leaky back flow preventers is a common problem. Universal replacement kits are available online for $20 to $30. Leaving a hose connected to the black tank flush can cause these to valves to stop working and leak.

The backflow preventer kits are a common repair part so they do fail from time to time. I ruined one by leaving a garden hose hooked to the flush inlet on a very hot day. The end of the hose was plugged by a closed spigot and the pressure ruined the check valve. Water then backed up into the valve when flushing the tank and it leaked. The tank flush quit working too until I replaced its backflow preventer. I went with a brass one instead of plastic. Works great again with no leaks.
