        <description>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.</description>
