Jabsco Twist 'n' Lock Manual Toilet Pump and Base Assembly Kit

The Jabsco Twist 'N' Lock Pump and Base Bundle combines the 29040-3000 manual pump assembly with the 29041-1000 replacement toilet base for compatible 29090 and 29120 toilets.

It is intended for a more extensive lower-toilet rebuild than a seal kit or pump-only replacement, while retaining the existing bowl, seat and sanitation pipework where serviceable.
