Low-flow toilets are designed to use less water per flush compared to traditional toilets. Typically, they use about 1.6 gallons of water, while older models can use up to 3.5 to 7 gallons. This reduction in water usage helps conserve resources and can lower water bills for households. These toilets work effectively by using advanced flushing technology, such as gravity-assisted or pressure-assisted systems. Many low-flow toilets also meet the standards set by the Environmental Protection Agency (EPA) under the WaterSense program, ensuring they provide efficient performance while minimizing water waste.
