Final Specification for High-Efficiency Lavatory (Bathroom Sink) Faucets

EPA released a final specification on October 1, 2007, for high-efficiency bathroom sink faucets and faucet accessories (e.g., aerators). Manufacturers that produce faucets and aerators meeting WaterSense efficiency and performance criteria can apply to have their products certified and earn the WaterSense label. Before submitting products for testing, manufacturers must have a partnership agreement with EPA in place.
