About a year ago I posted that I was having issues with the check valve in the city water inlet. Well, finally got around to tearing all that apart and found a stone inside the check valve - which was preventing it from closing.
The check valve is attached to the ball valve that is moved from "City Water" to "Tank Fill". The valve allows city water from the reel to enter the coach plumbing, or fill the tank when the valve is switched. When running on water pump, the check valve is suppose to close the connection to the hose reel. Mine was blocked open, so when we used the pump, we would have to cap the end of the hose on the reel.
The internal organs of the check valve were too damaged to use after the rock extraction, so I am on the lookout for a new one. I have pings into several places. If anyone has a source, it would be much appreciated.
Red circle is around the actual check valve.

I also replaced the hose on the reel when I had everything apart. I used a 50' 5/8" hose, reeled in as much as possible, and cut off what wouldn't fit. I think I have about 40ish feet on the reel. Nice to be rid of the weak 1/2" hose that was on there.
