buy a baby monitoring device pair. cheap $14 wally mart

should be good for 200-300 feet straight line distance

hook the transmitter ac adapter to the pump, when the pump turns on, it
powers the sound transmitter.

leave the receiver plugged in, when pump is on you will get clear sound of
actual pumpperfromance.

also, if the pump loses it's prime, the pitch should change and you may
react.

Looking for a way to activate a small lamp to show when a remote mounted
water pump is running. I know I have seen the method before but my dusty
brain cannot seem to find it. The pump is a 120volt unit mounted in a
remote pump house out of visual range or I would wire a light across the
pressure switch. I was thinking of something like an inductive coil
around the hot lead feeding a circuit that would power the light. No
problem working on the panel end. Ideas?
