    Raritan PH PowerFlush Electric/Manual Toilet - Marine Size - 12v - White [P101E12]

    2 in stock

    PH PowerFlush Electric/Manual Toilet - Marine Size - 12v - White PH Powerflush was designed to provide a unique option not available in any other marine toilet. Most toilets are either manual operation or electric macerating toilets. The Powerflush does not macerate but does offer the best of both worlds for those needing the option to switch to manual operation. The PH pump used on the PH Powerflush is a design that is timeless. The dual action pump is 66% larger in diameter than any competitive market. Because the housing is larger it more easily moves more water in and out of the bowl meaning you spend less time pumping and more time enjoying your time on the water. If water usage is a concern the intake water can easily be turned off and the unit can still be pumped to allow flushing with virtually no water being used. When installed as a Powerflush the simple push of a button activates the motor and arm that moves the piston up and down to flush the toilet. Should you lose power or need to conserve power the toilet converts easily to manual operation by removing the pin and inserting a handle into the pump.Features: PH PowerFlush electric model can be switched to manual superflush within minutes. Upgrading to PH SuperFlush and PowerFlush is fast and easy! Mounting base configuration matches the bolt pattern used on most competitive toilets. Clear the bowl with less strokes! Our robust double action piston pump is 66% larger than competitive models making its use quick, easy and efficient. Trouble free operation! Proprietary full size 1½” joker valve is specially designed to maintain pump performance. Slow close seat design - Seat locks in place while boat is rocking, no more slamming seats Full size joker valve which helps to prevent clogs and improves the flushing action WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
