Jabsco Pump Cylinder Assembly 29051-2000 for 29090-2 and 29120-2 Manual Toilets

The Jabsco Pump Cylinder Assembly (29051-2000) is a complete replacement pump cylinder kit built for Jabsco 29090-2 and 29120-2 manual marine toilets, 1998 and newer. This assembly replaces the core wear components of the toilet's manual pump mechanism, restoring proper priming, flushing, and discharge performance when the original cylinder, valve seat, or joker valve have worn out or lost their seal.

The kit is constructed with corrosion-resistant materials suited to fresh or salt water marine environments and is designed as a direct fit for the pump housing on compatible Jabsco manual toilets. It includes the top valve seat, the pump cylinder itself, two mounting screws, the discharge flange, the joker valve (which prevents back-flow and blockage), the discharge elbow, and the valve spring, giving owners everything needed to rebuild the pump section in one kit rather than sourcing individual parts separately.

This is a genuine Jabsco part intended for boat owners performing routine maintenance or repair on aging manual toilets, and it is compatible with Jabsco 29090-2 and 29120-2 models built from 1998 onward.
