In this video, I locate and replace a faulty brass 1/2″ check valve (one-way valve) in the RV water heater output piping. It 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.
