Check the model before ordering

Do not confuse the two-button wall switch at 1A with the controller at 1B. The 12V macerator is callout 12 and the discharge hose is callout 9. Verify toilet voltage, model generation, seat finish and the installed connector style before replacing electric or water components.

Turn off the water supply and disconnect electrical power as applicable before servicing. Follow the instructions for your exact model and replacement kit.
