You would think that establishing a definition for “showerhead” would be simple. But, as the Department of Energy (DOE) is discovering after issuing a draft interpretive rule on the matter, nothing is simple when it comes to getting people wet.
Some showerhead background
Back in early 1994, under the Energy Policy and Conservation Act (EPCA) of 1975, all showerheads manufactured in the U.S. could have a maximum flow no greater than 2.5 gallons per minute (gpm) at 80 psi. The intent, of course, was to save water, particularly hot water and its associated energy use.
