What is the WaterSense Specification for Showerheads?
The WaterSense specification applies to showerheads that have a maximum flow rate of 2.0 gallons per minute (gpm) or less. This represents a 20 percent reduction in showerhead flow rate over the current federal standard of 2.5 gpm, as specified by the Energy Policy Act of 1992. In addition to the water-efficiency criteria, WaterSense labeled showerheads must meet three key performance attributes that were identified through consumer testing: flow rate across a range of pressures, spray force, and spray coverage. These requirements are designed to ensure a high level of performance and user satisfaction with high-efficiency showerheads.
