Black water tank flush
We have a factory installed black water tank flush that I haven't yet used. We have been on a dozen or so trips but I refuse to be the guy holding up the dump station so I haven't utilized this yet. ...

There should be a backflow preventer in the line to the flusher. It may be built in to the flusher, or installed in the line. If it is factory installed, there should be one. your water line should also have a vacuum breaker at the faucet. Most campgrounds have them installed on the faucet. I have a splitter valve on the intake side of my water hose that attached to the campground faucet, and I just use that to connect to the flusher( with bfp installed).
