if using a pump only how do you turn it off

[Mike @ Facelift]

You are better off fitting a pump controller.

You will have to unplug the wires if you have no controller or on/off switch.

Pump controllers are a bit gay,
Fit a on off switch between pump and battery

[Mike @ Facelift]

I am a George Michael fan....

The thing about an on and off switch is that your pump will be on full whack.... You do need to think about water use....

Lol
Yep if you have a really small tank a controller is a good idea.
Otherwise just work quick with less complications.

not true you work faster with a 100 psi pump full whack less time scrubbing and rinsing you will use water the same, pump controllers are a waste of money the pump will turn it self on with the pressure switch, have worked this way for ages so do many others

just fit an inline switch on the live wire between the battery and pump, cheap and very easy to do.

A radio remote would make this more efficient

Whether to fit a controller depends greatly on what you want from your system.

If you want a pump running flat out the whole time running 5 to 10 litres a minute depending on your pump and drawing 8 amps an hour out of the battery then the control route is probably not for you. A control is not going to suit everyone in the same way that WFP does not suit every one.

The current crop of controls available are a far cry from the early models of 8 years ago and they do far more than just make the pump go faster or slower.

The pump pressure switch will stop the pump once the water flow is stopped either by twisting the hose or a tap.

As the pressure switch cuts out the pump is at maximum, working as hard as it possibly can and therefore drawing maximum current from the battery. Hence as the switch opens it is under great strain. The high current and the fact that the pump is an inductive load (with stored energy) means that the pressure switch contacts are likely to arc.

A controller provides an alternate method for managing water flow/Volume depending on what you want your system to do.
