Jabsco Twist ‘N’ Lock Complete Pump Assembly – Manual Marine Toilet (29040-3000)
A complete replacement pump assembly for Jabsco 29090-2 and 29120-2 Series manual marine toilets. When a service kit isn’t enough and the pump body itself is cracked, seized, or beyond rebuild, this drop-in assembly restores full flush function without replacing the entire toilet. The Twist ‘N’ Lock design allows for tool-free removal and reinstallation directly on the toilet base.

Parts Desk Insights
This is the right part when a customer’s Jabsco 29090-2 or 29120-2 manual head has a pump body that’s cracked, broken, or so worn that a seal kit won’t solve the problem. The Twist ‘N’ Lock mechanism is a genuine advantage in a cramped head compartment — no tools means faster swaps and less frustration. Before recommending this assembly, confirm the toilet series number (stamped on the pump body) and check whether a major service kit (29045-2000) would be sufficient — it’s a meaningful cost difference. If the bowl and base are also damaged, it may be more economical to recommend a full toilet replacement instead.
