Faucet Aerators

According to WaterSense, faucets account for more than 15% of indoor household water use—more than
1 trillion gallons of water across the United States each year.

Although federal law requires that new faucets not exceed 2.2 gallons per minute (gpm) at 60 psi, older faucets can flow at rates as high as 3 to 7 gpm.

Inexpensive and simple to install, high-efficiency faucet aerators (located at the tip of the faucet), mix air with water to reduce flow, without sacrificing performance.

Most faucets have aerators, or have threads on the inside or outside of the faucet to accept an aerator. Bring your old aerator (and any associated washers) to the store when purchasing a new one, to ensure that the new aerator will fit on the faucet fixture.

The aerator flow rate is imprinted on the side of the aerator and should read 2.2 gpm or lower.





Replacing an Aerator

Twist aerator clockwise to loosen and remove from the faucet. You may need to use a wrench. Wrap a rag around the aerator to avoid scratching the finish.
