Even when all water is shut off in the camper, my water pump keeps running. Even when the tank is completely empty. Does anyone know what is causing this?
The pump is pressure regulated and kicks on when pressure in the water storage tank drops, such as it does when you open a water faucet. Either the pressure regulator is defective or you have a leak in the plumbing. Somewhere there is an electric switch where you can turn the pump off manually, either on the pump or near the pump. I suggest you shut it off until you can determine what the problem is.
I might be miss-understanding your question. If you have no water in the tank then the pump will run all the time because you won't build enough pressure in the system to shut it off. There should be a switch to turn it off manually. If your system has water in it and pump still won't shut off then it could be several different things: 1. Pump is bad and leaking internally... do you have good pressure at the faucet? 2. There should be a pressure cut-out switch somewhere near the pump. This switch should shutoff the pump when the ideal pressure is reached and prevent the pump from over pressurizing the system. Make sure it is not stuck closed. (May have to remove to test) Check for continuity across the terminals with pressure with the pressure on and off. If it doesn't' change... replace. 3. You could have a leak somewhere in the system not allowing the system to build pressure. 4. There may be a pressure relief valve somewhere in the system that is stuck open and dumping your pressure back into the suction side of the pump. Good Luck!
