1.2kIn this video, I locate and replace a faulty brass 1/2" check valve (one-way valve) in the RV water heater output piping. Turns out the rubber o-ring had split and the spring was vibrating against the brass casing making a heck of a racket.
I was able to narrow down the problem to the check valve while doing my routine water heater flushing. I noticed that even though the winterizing valve was in the correct position I was still getting water trickling into the water heater.

3I have always wondered, when showering in my Cougar 5th wheel, I have noticed that when I pause the shower with the shower head, when I continue I get a moment of cold water. Maybe this valve is the reason.
During pauses, the water still trickles a small amount, and the water from the supply takes the path of least resistance. This check valve is the resistance, so that is why it it cool water.

11We have a TT we were finding the hot water was migrating down the cold line and when we turned on the ball valve to rinse off we were scalded ! So we added a one way check valve to the shower cold side, with a ball shutoff between the tap and shower head. This saves on wasting water and no scalding when turning shower on to rinse off. Hope this helps.
