HI all, I have a 2014 OutdoorsRV and my “sani flush” seems to be clogged. When I hook up the hose, turn on water and open the dump valve, nothing comes out. Clearly the hose has tremendous pressure....
I had that same problem. The dealer replaced the check valve and said they tested it. Well on the trip out it didn't work. Did some checking removed the underneath cover and saw the hose to the tank was kinked. I added a pex elbow support no problems since.
Though it did make me curious about the dealer's service tech.
