Dual-Flush Toilets

A dual-flush toilet is a type of high-efficiency fixture. Dual-flush toilets are those that have two levels of flushing – a higher water use flush (full flush) for solids and a lower water use one (reduced flush) for liquids. The effective flush volume of a dual flush toilet is 1.28 gallons per flush. Dual-flush toilets are available in tank or flush valve types.
