After de-winterizing my RV and taking it on a several day trip, I noticed a new problem has developed.
The water pump keeps turning on every few seconds for about a second. The video shows it better than I can describe.
I've checked the external shower, toilet, water heater and sink for possible leaks and I don't see any at all. There's no sign of even a drip coming out from the places I can visibly check.
Does anyone have any hints on what might be happening or how I can diagnose it? This is the original pump.
When in actual use, the pump and water pressure are just fine. For now I'm just turning off the pump when I am not using it.
