Yes flip off that water pump switch when you leave. Always! I learned the hard way.
Here is how it happened:
The pump builds pressure and then shuts off. This is normal.
BUT, when you are close to being low on water in the fresh tank,
You are away from the camper,
The pump kicks in to just top off the pressure as it was on the edge of almost turning on,
And the pump sucks an air bubble from the tank being low as it is sucking air above the water line in the tank….
Well the pump won’t prime and will just plain run for ever. Since it is not building pressure, sucking air, it will eventually dry lock it self. The normal surging stops banging and you can barely hear the motor running. Until you return several hours later and smell that horrible electrical insulation smell when the pump almost burnt up when you walk in the camper … The mind went racing and Thank the good Lord it did not catch fire.
Well ever since, we flip the switch OFF, when we go out the door. Now is habit.
