Jabsco 18916-0040 Pressure Switch, 40 PSI
The Jabsco 18916-0040 is a genuine Jabsco pressure switch set at 40 PSI for a Jabsco diaphragm water pump. It is listed for Jabsco 31670 series pumps and the 59451 series.
The pressure switch turns the pump on when a faucet or outlet opens and pressure drops, and off again when the system reaches its set pressure. A worn or failed switch can make the pump cycle rapidly, run on, or fail to start. Isolate power before changing it, and check the system for leaks, since a leak also causes the pump to cycle.

Frequently Asked Questions
Q: Does the pump need a new switch if it will not stop?
It may. Also check for air leaks on the suction side and a closed outlet.
Q: Can I change to a different pressure setting?
Only to a setting approved for your pump. Too high a setting can overload the motor.
Q: Why does my pump cycle on and off?
Leaks in the system, a failed accumulator or a worn switch are the usual causes.
Q: Should I turn off power first?
Yes. Isolate the power before removing the switch.
