GPF (Gallons Per Flush)

GPF, or Gallons Per Flush, is a measure of the amount of water used by a toilet per flush cycle. It is a key indicator of water efficiency, with modern toilets designed to use less water compared to older models. The current federal standard in the United States is 1.6 GPF, while high-efficiency toilets (HETs) are designed to use 1.28 GPF or less. Reducing GPF is part of water conservation efforts, as it helps save water, reduce utility costs, and support sustainable resource management. Understanding GPF is important when selecting toilets for residential, commercial, or public facilities, as it directly impacts water usage and compliance with water efficiency standards. Dual-flush toilets offer users the option of selecting a lower GPF for liquid waste or a higher GPF for solid waste, further enhancing water conservation.
