The Glenwall 1.28 GPF (Water Efficient) Elongated Wall-Mount Toilets (Seat Not Included) features the powerful VorMax flushing technology. The VorMax unparalleled scrubbing action circulates water around the bowl from top to bottom, leaving it twice as clean as a conventional toilet while using a water-conserving 1.28 gallons of water. It has a 50% quieter flush than pressure-assist configurations and ensures the complete removal of paper seat covers.
