The U.S. Environmental Protection
Agency’s WaterSense program released its final specification for showerheads on
March 4, 2010.
Showering is one of the leading ways we use water in the home, accounting for
nearly 17% of residential indoor water use, or about 30 gallons per household
per day. WaterSense-labeled showerheads will use 20% less water and perform
as well or better than standard models. The final specification sets the
maximum flow rate at 2.0 gallons per minute (gpm) at a flowing pressure of 80
pounds per square inch (psi).
