Black tank flush 2009 Big Country
Hooked hose up to flush black tank, water showed up in floor of fifth wheel. What kind of problem do I have and how hard is it to fix. Any help would be appreciated. Thanks

Yep, most likely that antisiphon/vacuum breaker valve. Failure of those valves is a common problem. If you are lucky it will be under the sink in the bathroom vanity cabinet. If not so lucky it will be inside a wall, likely behind the shower.
Look for something like this. Or it could be clear plastic.
