Product Details

About This Product

This Red Lion low pressure switch is a smart little safety device for your well or jet pump.
Basically, if your water level drops too low and the pump starts sucking air, this switch senses the pressure drop (about 10 PSI below the cut-in) and shuts the pump off automatically.
That's huge because running a pump dry can melt the impeller and burn out the motor in no time.
