A high-efficiency toilet (HET) is designed to use significantly less water than traditional toilets while maintaining effective flushing performance. Typically, HETs use 1.28 gallons per flush (GPF) or less, compared to the standard 1.6 GPF. This reduction in water usage helps conserve resources and can lower water bills for households. These toilets often feature advanced flushing technologies, such as dual-flush systems or pressure-assisted mechanisms, which enhance their efficiency. Many high-efficiency toilets are certified by the Environmental Protection Agency (EPA) under the WaterSense program, ensuring they meet strict performance and efficiency standards.
