Jabsco 18916-1035 Pressure Switch, 35 PSI
The Jabsco 18916-1035 is a genuine Jabsco pressure switch set at 35 PSI for a Jabsco diaphragm water pump. It uses EPDM elastomers. Jabsco uses this part number on specific models only, so match it against the parts list for the model number on your pump plate before ordering.
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: 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.
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.
