Water System Check Valve
Just wanted to pass on the fix to an issue we've had.
Over the last season or two I've noticed our water supply hose dribbles when I disconnect it from the campground supply. My solution has been to ensure the end cap is tightly screwed on before I retract the hose reel and hit the road. Yesterday I disconnected it while the coach pump was turned on ... it was a lot more than a dribble!
The water system has a check valve, located in the main plumbing system once it leaves the hose reel. It's all neat and tidy, the line appears to be a crimped assembly installed by the factory. However, after some research, I found the check valve is manufactured by SharkBite and removal just requires you to push down the collars on each end. A new 3/4" check valve was less than $20 at the local hardware store. They also sell a plastic snap on collar retracting tool for less than $2, but you can also use an adjustable wrench, set to the O/D of the pipe, to push the collar in. It literally took less than a minute to swap the valve out ... which completely stopped any back flow from the supply hose!
I did check the inside of the old valve, found some metallic looking debris, which had prevented the valve from shutting off.
