VitrA USA offers the 1.0 gpf (gallons per flush) Pressure Assist system, a supplementary water-saving toilet system in addition to its Dual Flush. The new 1.0 gpf toilet saves 38 percent more water compared to a standard 1.6 gpf system. Besides saving water, the Pressure Assist system uses a specialized flushing mechanism that provides added force to water during flushing to significantly enhance the performance of the traditional siphonic discharge. This added pressure augments the level of discharge function and bowl cleaning without increasing the gpf; thus, decreasing water consumption.
