I have a 2000 Discovery motorhome and my problem is that the water pump is always on. I shut off the water pump switch at the main control panel and I go turn on the water at the faucet and the pump runs. It doesn't matter which of my three water pump switches that I turn off, I can shut off all three and the pump will still run when I turn on the water. Any suggestions?

Sounds like a short that is keeping the line to the pump hot. You may have to test all the switchs to see if one is not switching off.

Sounds like the pump 'controller' is shorted in the 'on' state.

Don't know what brand of controller is being used but here is a manual.

Are your switches of the "momentary" type, or conventional on/off? The momentary would be part of a system that uses a controller.

Many of the units with three pump switches use a relay to activate the pump.
The relay may be stuck closed or one of the switches may be stuck closed.
