I use a 'one shot' remote, it's amazing, stops the pump at the touch of a button, pressure stops in hose within 3 seconds, means I save so much water, and my pump is used less, as in between windows and extending pole etc, my pump is off, then at the touch of a button it's back on instantly. Can't fault it. Works up to 100meters. Dramatically improves pump, battery and water life.
