Overview
A jet pump loses performance in a few predictable places: the impeller and diffuser wear, the shaft seal weeps, the injector or nozzle fouls, and the pressure switch drifts. Each of those is a part on this page rather than a reason to replace the pump.
Parts are listed against the pump they fit: JP shallow well, JPC convertible, or both. Check the model on the pump nameplate before ordering — JP and JPC share some parts but not all of them.

Before You OrderTake the model and, where present, the date code from the pump nameplate. On a convertible pump, the injector and nozzle are matched to the setting depth — tell us the well depth if you are changing them.
