Overview
The Jabsco 44106-1000 is a replacement joker/check valve for selected Jabsco electric marine toilets and electric conversion kits. It fits in the discharge elbow at the pump-cylinder connection, where it helps keep flow moving in one direction and reduces waste returning toward the bowl.
Fitment is confirmed for 37010 Series electric toilets, 37045 and 37245 Quiet Flush toilets, and 37055 and 37255 Quiet Flush conversion kits. The same valve is used across 12V and 24V versions within those supported ranges, so the main check before ordering is the toilet series rather than system voltage.
This is a service part, not a universal toilet valve. Some older or discontinued Jabsco electric toilet layouts use a different joker valve, so matching the exact toilet or conversion-kit series is the safest way to confirm fit.
Key features
- Replacement joker/check valve for the discharge side of supported Jabsco electric marine toilet systems
- Fits inside the discharge elbow and at the pump-cylinder connection
- Confirmed fit for 37010 Series electric toilets
- Also used on 37045 and 37245 Quiet Flush toilets, plus 37055 and 37255 Quiet Flush conversion kits
- Used across both 12V and 24V versions within those supported series
- Useful when discharge flow is no longer holding its direction and waste starts creeping back toward the bowl
Compatibility and fit
This part makes sense for owners keeping an existing Jabsco electric head in service rather than replacing the full base or pump assembly. It is a practical match for boats with a 37010 Series toilet, a 37045 or 37245 Quiet Flush installation, or a 37055 or 37255 conversion setup already in place.
On boats with older refits, discontinued toilet layouts, or mixed components from previous repairs, it is worth checking the service parts layout for the exact base and pump assembly before ordering. A joker valve can look similar across models while still being the wrong part for the housing it needs to seat into.
Installation and service
Access is at the discharge elbow and pump-cylinder connection, so this is usually replaced during discharge-side service rather than as a top-side bowl repair. Before opening the system, isolate electrical power and close the relevant seacocks. While the assembly is apart, it is also a good time to inspect the elbow, hose connection, and surrounding seals for wear or buildup.
This part is a good fit for boat owners dealing with backflow on a supported Jabsco electric toilet and wanting to restore normal one-way discharge without changing the whole toilet base. It is especially relevant on boats that see frequent use, long periods at the dock, or seasonal recommissioning where head service items often show up all at once.
