Complete pump assembly for Jabsco Manual Toilets
The new design uses a remodelled piston in the pump-out assembly. At the end of normal pumping out, at the bottom of the pump stroke, the user simply turns the handle through 90 deg which locks the piston down onto the base outlet valve, keeping it securely shut.Turning the handle to the normal operating position opens the lock again.
