Dual-Flush Toilets and LEED Certification





A dual-flush fixture is classified as a HET. This fixture is comprised of two different flushing options. One option uses the full flush — 1.6 or 1.28 gpf — to clear the trap, similar to a standard fixture. The second option uses less water — up to 1.1 gpf — which is enough to clear the trap of liquid waste.

Users typically realize the full-flush option is unnecessary for every use and generally take the opportunity to use less water. Dual-flush fixtures are best suited for applications in which the same people use the same restroom regularly. For LEED certification, dual-flush fixtures are recommended for use only in women's or unisex restrooms. In men's restrooms, urinals are used for liquid waste, and most toilets are used for solid waste.
