if you use a 12V water pump, as used by all the major manufacturers, they have a built in pressure switch. If you install a B&Q supplied hozelock tap @ approx £3.99 or if you want chromed brass, we have them cheap too.
The tap located on your pole hose will thus automatically shut off the pump when you decide, remotely.
Advantages over dink/dink remote of inline tap;
No batteries, works when wet, cant lose it, etc. etc.
Might sound a bit obvious, but we were approached by 3 operators last year with the same idea.
Reliability and robustness in all weathers should always be paramount in selecting equipment, so before you part with £45, nip to B&Q with less than a fiver and try a tap first.!
