Check the water-inlet and flush controls before ordering
The 98305 is a 12V Compass ECO High toilet, but the manufacturer supplies its fresh-water solenoid and ECO rocker-switch components separately. A pressurized fresh-water installation uses a solenoid, while a raw-water installation uses an inlet pump, strainer and the appropriate wiring/control kit. Do not order both water-inlet arrangements without confirming the installed system.
The MAC4 waste-discharge pump T-PF.P01C is separate from the raw-water inlet pump T-PF.P27. They are not interchangeable. The 24V counterparts are different parts.
