WaterSense Considers Revising and Broadening Faucet Specification

March 8, 2024
EPA is considering lowering the maximum flow rate for private lavatory faucets to earn the WaterSense label to either 1.2 GPM or 1.0 GPM.

To reflect changes in the plumbing marketplace and encourage more water savings in homes and businesses, the US Environmental Protection Agency (EPA) is planning to revise its criteria for faucets and faucet accessories to earn the WaterSense® label. Today, WaterSense issued a Notice of Intent to revise its High-Efficiency Lavatory Faucet Specification, which covers faucets and accessories such as aerators sold for residential and other private use.

EPA released the specification in 2007; since then, most faucets of this type now sold in the United States meet or exceed the current WaterSense maximum flow rate of 1.5 gallons per minute (GPM). What’s more, several states have adopted regulations that require that private lavatory faucets not exceed flow rates of 1.5 GPM, and four states do not allow the sale of these faucets with a flow rate over 1.2 GPM.

To address this growth of water-saving fixtures in the marketplace, EPA is considering lowering the maximum flow rate for private lavatory faucets to earn the WaterSense label to either 1.2 GPM or 1.0 GPM. WaterSense will also clarify that bar sink faucets are covered by the specification. In addition, EPA is considering allowing other types of faucets to earn the WaterSense label, including public use lavatory faucets, kitchen faucets, and metering and self-closing faucets.

EPA has identified the water efficiency and performance criteria it is considering for a revised specification for faucets, as well as key discussion points where it is seeking feedback on the revision. The Notice of Intent, including potential revisions and discussion points, can be reviewed at
