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

Might be the vacuum break valve. The flush water line has a loop in it that is positioned higher than the outside water flush connection. The vacuum break valve is located at the top of this loop. Mine is located under the bathroom sink.
Also called anti-siphon valve.
