Typically they are installed very near the pump on the hose from the fresh water tank. If your pumps check valve is leaking, you will hear the water flowing backwards through the pump each time it shuts off. Also, it that is happening, when you hook up city water supply, it will leak through the pump and eventually overflow the fresh water tank. read the previous post as it might be an easy fix to run all the taps and clear the pump.
