Jabsco 29042-0000 Pump Valve Gasket
Keep your Jabsco Twist 'N' Lock manual marine toilet pumping cleanly with this OEM replacement pump valve gasket. The valve gasket seals the pump chamber during each stroke cycle, maintaining the pressure differential that moves waste efficiently through the system. When this gasket wears or deforms, pump action becomes spongy, inefficient, or fails to clear the bowl completely.
Parts Desk Insights
This is the correct part when your Jabsco manual toilet is pumping but not clearing the bowl effectively, or when you notice resistance has dropped off and the pump feels loose or unresponsive. It is a standard wear item and should be inspected at every annual service interval. If you're already servicing the pump, replacing this gasket at the same time as the O-rings and seals is strongly recommended — the Jabsco Major Service Kit (29045-2000) includes this gasket along with all other pump wear parts and is the most cost-effective approach for a full service. Confirm your toilet uses the Twist 'N' Lock pump configuration before ordering.
