TechNote 07 Fixtures Low-Flow Showerheads  


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). Low-flow shower heads are designed to operate within 1.5 gallons of water per minute. To be more efficient, water droplet size and direction is controlled to help reduce and focus the water flow. Low-flow shower heads do not reduce water pressure; instead they restrict flow by forcing water through small apertures which increases the velocity of the water. Low-flow shower heads are designed to be as effective as conventional shower heads.
