    Low Pressure Pump Cut-Off Switch for Well & Jet Pumps

    • PROTECTS YOUR PUMP: running a pump without water can severely damage a pump; this switch automatically shuts pump off when pressure decreases 10 PSI which prevents the pump from running dry
    • M4 TYPE: has manual reset lever and 1/4-inch Female NPT threading at the bottom of the unit; once well has recovered, hold down lever to manually re-start pump
    • PRESET FOR 30-50 PSI OPERATION: cut in pressure = 30 PSI; cut-off pressure = 50 PSI, adjustable
