Water pump switches- newbie question

We have a switch labeled "water pump" in the outside compartment with our hookups. We have another one inside on the wall with our slide switch, generator switch and thermostat.

Are we supposed to turn both of the water pump switches on to use our water when not hooked up to city water? Are we only supposed to use one of them?

(The manual doesn't make any reference to there being two switches.)

If one is on and you flip the other it will turn the pump off. It's just so you have control at either location.

They work just like your 3-way light switches at home

Negative. With a 12 volt system, if any of the water pump switches are "on", then the water pump is on. In my Allegro Bus I have a pump switch on the monitor panel, a switch in the wet bay, and a switch in the bathroom.

Sounds like YOU have a water pump controller with momentary switches
Turn ANY switch ON....ground circuit is made and pump runs on demand
Turn ANY switch OFF...ground circuit is broken/pump doesn't run


OP could have same type if switches are momentary switches
If not then they could be 3-way circuit

I've never seen or heard of one like that, but if you say yours works that way, I'll have to believe. I think Old Bisquit meant to say yous must be withOUT momentary switches and thus has defined On & Off positions. Most rigs use momentary switches that signal a pump controller to switch the pump state.


Technically the wiring is not the same as a residential 3-way switch, but the net effect is the same. Each switch causes a change in the pump state. If Off it goes On and if On its goes Off.
