Summary
The U.S. Energy Policy Act of 1992 requires that all faucet fixtures manufactured in the United States restrict maximum water flow at or below 2.5 gallons per minute (gpm). Ultra low-flow faucets produce 0.5 to 1.5 gallons of water per minute, reducing water usage from 40 percent to 70 percent. Ultra low-flow faucets are designed to be as effective as conventional faucets.
