Water pump switch

I have a 1999 Winnebago Chieftain. There are 3 switches to turn the water pump on/off. The one on the main control panel is the only one with the on/off label. The switch in the bathroom and one at the outside shower have no label. And, yes, depending on where the pump is located, you should be able to hear the "hum" when you are running water.

Typical water pump switch reverts back to same position after you press it. Press it once and the pump is on - press it again and the pump turns off. Sometimes there is a light near the switch which indicates the pump is on .. sometimes not. There are often many water pump switches (kitchen, bathroom, outside shower etc) which are connected to a relay switch. If you turn it on in the bathroom your wife can immediately turn it off in the kitchen ... in short - no such thing as std "on/off" position.

faucet open pump noise its on faucet open no noise not on no water

You might hear a short noise when you first turn on the water pump switch which is the lines being filled. After that initial noise, you should NOT hear any noise UNLESS you are running water. If you do NOT have a faucet on and you hear a noise AFTER the initial filling of the water lines, you either have a hopefully small leak in the lines causing a lack of pressure OR you do not have enough water in your fresh water tank to fill the water lines. How much noise you hear WHILE you are running water will depend upon your water pump and how it is mounted - i.e. how much it vibrates while running.

Replace the switch with a lighted one. This will remove all doubt.

If you have multiple switches then it's often like having 2 switches controlling a light or outlet in your home. Which way is on for one switch depends on the position of the other switch.

With shore water disconnected open a faucet.If no water comes out the switch in off. If water comes out the switch is on.
That is assuming the pump works and there is water in the tank of course.
