In order to earn the WaterSense label,
faucets must be independently tested and certified by a licensed certifying
body to meet EPA’s water-efficiency and performance criteria. To meet the
criteria, faucets and accessories such as aerators cannot flow at a rate of
more than 1.5 gallons per minute, or less than 0.8 gpm. Working with
stakeholders, EPA chose a rate that ensures both water savings and that the
faucet flow rate will continue to meet the needs of the user.
WaterSense-labeled lav faucets should be
hitting retailers and wholesalers in 2008.
