Sump pump Monitor

Sump pump Monitor My parents have a cistern and a sump pump which would be useful to have some sort of water level monitoring. In the past, we would check the cistern level with a pressure gauge calibrated in inches of water. There was a rubber squeeze bulb which which would pressurize a plastic line which fed into the cistern, and the resulting level would be shown on the gauge.

X10 Interfacing X10 Mini Timer power supply The LCD display seems to die after a few years (on three units I've used) so I figured out the pinout. 4N35's are used internally for opto-isolation, The power is from a transformer internally, with a rectifier and a capacitor.
