Sani Flush

mud daubers?

Mine hose was also kinked near the sprayer. once the kink was fixed (by me) leaks solved.

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.

Pardon my ignorance--is the check valve to prevent “back flow.” Is it close to the connection with the hose?

Good idea. I will see if i can remove the email connection from the trailer and look inside; our underside is sealed in this unit, so I can’t get easy access to this area.

When I last did mine. The water stopped coming out, then I heard a rush of water. It did it a couple more times....
Obviously, I had a "solid" damn somewhere that when the tank got some water in it, the weight of the water cleared it.

I use the geo method to keep my black tank clean, so I suspect I have not been putting enough water in the black tank when using it...

I don’t hear it spraying... and the pressure backing into the hose gives me a pretty good indication there is blockage somewhere along the line.

I thought about putting some detergent in the tank and then filling with a garden hose, hoping the clean (ish) water + detergent would break through anything compromising the nozzle.

that is the key factor. is the hose kinked, nozzle plugged, etc?
crawl under and undo hose from nozzle base and see if water comes out hose. if so, nozzle is plugged.
