HC3100 Low Water Shut-Off and Pump Protector

Works great! I'm using it to protect the pump on my small pond. Fall leaves were clogging the strainer basket and the pump would run dry. It shuts off now when this happens. Very easy to install. Other units I looked at simply cycled the pump on/off while the water level dropped and rose causing the pump to continuously start and stop. This unit simply shuts off the pump. Perfect!

I'm using it in my rain water collection system to protect my pressure pump which irrigates the yard. So far, I haven't emptied my tank, so it is hard to say for sure that it will do what I want it to do. But, I tested it and it worked.
