The PHII and PHEII both operate by using a double action piston pump that simultaneously draws new flush water as it discharges the wastewater. By using raw water for flushing, on board water supplies can be reserved for essential freshwater use.

The PHII pump has a unique, easily replaceable seal cartridge. A simple quarter turn of the inlet water valve control knob allows the bowl to be pumped dry without using additional water. This provides the user with the option of emptying the bowl while in heavy seas. A special air vent reduces back pressure.

Electric PHEIIs operate by the push of a button and should be installed with a momentary or Push Button Switch (PBS) and a Continuous Duty Solenoid (CDS). In the case of power loss, the PHEII comes with a lever handle for temporary manual operation. Manual PHIIs can be easily converted to electric operation with a PHECKII Conversion Kit
