Jabsco 40 PSI Replacement Pressure Switch

The Jabsco 18916-0040 Replacement Pressure Switch is built for the 31595, 31600, 31620, and 31630 Series pumps. It's the component that turns the pump on and off automatically as system pressure rises and falls.

Rated at 40 PSI, it's matched to a slightly lower switching point than Jabsco's 50 PSI switch. It's worth confirming which pressure rating the pump was originally set up with before ordering.

A pressure switch is one of the more common failure points on a freshwater pump system. Replacing it is a straightforward fix for a pump that runs constantly or won't start at all. Shop more bilge and water pumps.
