Dual Flush toilets provide the means of saving water and money by providing the highest performance capability available  in the ULF (Ultra-Low Fixture) category. You may use the partial flush (1.1 gallons of water) to discharge liquid waste and the full flush(1.6 gallons of water) tothoroughly clean the toilet bowl of solid waste. The Dual Flush is currently the only system in the world that provides this pressurized dual function capability. The patent pending design of the Dual Flush valve cartridge provides superior flushing performance for either liquid or solid waste elimination. This is accomplished by the incoming water compressing the air inside the pressure vessel, the compressed air creates a piston effect and the air drives the water into the bowl for effective cleaning.
