A low-flow toilet is a type of toilet designed to use less water per flush compared to traditional models. Typically, these toilets use about 1.6 gallons of water or less, while older toilets 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. Low-flow toilets often employ advanced flushing technology, such as pressure-assisted systems or dual-flush options, which allow users to choose between a full or partial flush. Many regions encourage the use of low-flow toilets through incentives or regulations, contributing to environmental sustainability efforts.
