Jabsco Valve Cover Assembly

As the complete top-section of the manual pump, it contains the intake valve and the "Twist 'n' Lock" mechanism on modern versions. The specific part number for the assembly varies by toilet model, though newer versions are often backward compatible.

Part numbers and compatibility:

Part #29094-3000: This is the latest version of the valve cover assembly and is compatible with all Jabsco manual toilets from 1986 onwards.
Features: Includes the white "Twist 'n' Lock" handle and is a direct replacement for toilets manufactured from 2008 onwards (models ending in -3000).
Backward compatible: It can also be used to upgrade older models (up to 1997 and 1998–2007).
Superseded part numbers: Older models used different valve covers, but these have been replaced by the 29094-3000 assembly, which offers the updated "Twist 'n' Lock" functionality.
