Jabsco Twist n' Lock Manual Toilet Pump Assembly, For 29090 & 29120 Series

Overview

The Jabsco 29040-3000 is a replacement Twist n' Lock pump assembly for Jabsco manual marine toilets in the 29090 and 29120 series. It is the pump section used when the original assembly is worn, hard to prime, leaking, or no longer holding the bowl as it should between uses.

The Twist n' Lock handle locks the pump to help reduce backflow into the bowl when the toilet is not in use. A base valve gasket is included, which makes this a practical service part for boats that still rely on a manual head in the cabin, coastal cruiser, or day boat.

Key features

• Replacement pump assembly for Jabsco manual marine toilets in the 29090 and 29120 series
• Twist n' Lock handle helps reduce waste water backflow into the bowl when the pump is locked
• Fits current Twist n' Lock manual toilet versions and older black-handle manual toilet versions within the same family
• Supplied with a base valve gasket for service and reassembly
• Works as a pump-section replacement for manual heads, without replacing the complete toilet

Compatibility and fit

This pump assembly is for Jabsco manual toilet installations built around the 29090 and 29120 series platform. It suits toilets found on both sailboats and powerboats where a manual sanitation system is still the preferred setup.

Before ordering, match your toilet series and pump style rather than relying only on the bowl shape. It is intended for manual Jabsco heads, not electric toilet systems or conversion kits.

Installation and setup

Replacement is a straightforward service job with common hand tools. In most cases the work centers on removing the old pump section and fitting the new assembly in its place, which is often simpler than opening the existing pump and chasing several worn internal parts.

As with any marine toilet service, close the inlet and discharge seacocks before starting and expect some residual water in the hose run. This part is a good match for owners maintaining an onboard manual head that needs dependable day-to-day use without changing the rest of the sanitation layout.
