Most of us know we can save water if we turn off the tap while brushing our teeth (as much as 3,000 gallons per year!), but did you know that there are products that will help save water when you turn on the tap too? WaterSense labeled faucets and faucet accessories (such as aerators) are high–performing, water–efficient fixtures that will help you reduce water use in your home and save money on water bills. By retrofitting your entire bathroom with WaterSense labeled fixtures, you can save even more.

WaterSense labeled bathroom sink faucets and accessories that use a maximum of 1.5 gallons per minute can reduce a sink's water flow by 30 percent or more from the standard flow of 2.2 gallons per minute without sacrificing performance. We could save billions of gallons nationwide each year by retrofitting bathroom sink faucets with models that have earned the WaterSense label.
All products bearing the WaterSense label complete an independent certification process to ensure they meet EPA criteria. Faucets and faucet accessories—products that can be attached easily to existing faucets to save water—that obtain the WaterSense label have demonstrated both water efficiency and the ability to provide ample flow.Whether replacing an older, inefficient faucet that's wasting water and money, or simply looking for options to reduce water use in your home, choose a WaterSense labeled bathroom sink faucet or aerator. WaterSense labeled models are available at a wide variety of price points and a broad range of styles and in many areas, utilities offer rebates and vouchers that can lower the price even further. The next time you wash your hands or brush your teeth, you'll know that you're doing your part to help protect our precious water resources.
Replacing old, inefficient faucets and aerators with WaterSense labeled models can save the average family 700 gallons of water per year, equal to the amount of water needed to take 45 showers. Also, since these water savings reduce demands on water heaters, households will also save enough energy to run a hairdryer 17 minutes a day for a year. Achieving these savings can be as easy as twisting on a WaterSense labeled aerator, which can cost as little as a few dollars.
If every home in the United States replaced existing faucets and aerators with WaterSense labeled models, we could save nearly $1.3 billion in water and energy costs and 69 billion gallons of water across the country annually—equivalent to the annual household water needs of more than 680,000 American homes.
Replacing old, inefficient bathroom faucets and aerators with WaterSense labeled models can save the average family nearly 11,000 gallons of water over the faucets' lifetime. Watch the video below to find out how easy it is to replace your faucet aerator.

As a part of the specification development process WaterSense reviewed product data and investigated user satisfaction studies to select flow rate criteria that would generally provide no noticeable difference for most users in performing routine tasks such as shaving and handwashing. WaterSense also considered the impact of pressure changes on product flow rates and established a minimum flow to ensure user satisfaction in homes with low water pressure.
All WaterSense labeled lavatory faucets and accessories are independently certified to meet performance criteria to ensure user satisfaction and health and safety in the following areas:
- Life cycle: Ensures lavatory faucets continue to function as intended through their expected life cycle.
- Lead-free: Ensures plumbing fittings intended to dispense water for human consumption are lead-free.
- Minimum flow rate: Ensures an adequate flow rate necessary for typical end uses is provided at low water pressure.
See the Performance Overview for more information on how WaterSense assessed performance when developing the specification.
EPA released a final specification on October 1, 2007, for bathroom sink faucets and faucet accessories (e.g., aerators).

Manufacturers that produce faucets and aerators meeting EPA's efficiency and performance criteria can apply to have their products certified to earn the WaterSense label. Before submitting products for testing, manufacturers must have a partnership agreement with EPA in place. Visit the manufacturer section on the partner page to learn more.
