This Eco-Flo pressure switch gives a jet or submersible well pump automatic on/off control. Used in conjunction with a diaphragm pressure tank or a galvanized tank, it closes to start the pump when system pressure falls to 20 PSI and opens to stop the pump at 40 PSI.

• Cut-in 20 PSI / cut-out 40 PSI
• For automatic operation of jet and submersible well pumps
• For use with a diaphragm pressure tank or galvanized tank
• Manufacturer model: EFPSW2040

Tip: Pressure switches are sold by pressure range, so check the cut-in and cut-out your system is set up for before swapping one in. A switch and a pressure tank work as a pair - if the tank has lost its charge, a new switch will not stop the pump from short-cycling.
