Description The Jabsco Replacement Pump Assembly Twist ’n’ Lock 29040-3000 is a complete pump unit designed for Jabsco 29090 and 29120 series manual marine toilets. This assembly replaces the entire pump mechanism, restoring correct flushing performance, suction, and discharge control. The Twist ’n’ Lock handle allows the pump to be locked in the closed position, preventing flooding or backflow when the vessel is underway or unattended. Manufactured from corrosion-resistant, marine-grade materials, the assembly is suitable for both saltwater and freshwater installations and is ideal when internal pump components are excessively worn or damaged beyond service kit repair. The Jabsco manual toilet pump comes complete with base valve gasket included and a single stainless steel screw in case when changing the pump a screw breaks.
