Jabsco 50 PSI Diaphragm Pump Pressure Switch

The Jabsco 18916-0050 is a pressure switch built specifically for a Jabsco diaphragm pump. It's the component that turns the pump on and off automatically as water pressure in the system rises and falls.

Rated at 50 PSI, it's matched to the pressure range a standard Jabsco freshwater pump runs at. It's worth confirming the pump's rated pressure before ordering to make sure the switch trips at the right point.

Replacing a failed pressure switch is a common, inexpensive fix for a freshwater pump that won't shut off or won't start. There's no need to replace the whole pump over one worn part. Browse more bilge and water pumps.
