Low-flow toilets are designed to use less water per flush compared to traditional toilets. Typically, they use about 1.6 gallons of water or less, while older models can use up to 3.5 to 7 gallons. This reduction in water usage helps conserve water resources and can lead to lower water bills for households. These toilets work by utilizing advanced flushing technology, such as gravity-assisted or pressure-assisted systems, to effectively remove waste. Many low-flow toilets are also designed to meet specific efficiency standards set by organizations like the Environmental Protection Agency (EPA) through their WaterSense program, promoting water-saving products.
