ASA applauds DOE reversal of weakend showerhead standards
2.5 gpm rule again applies to fixtures with more than one showerhead.
On Dec. 16, the U.S. Department of Energy officially reversed weakened showerhead standards adopted under the previous administration.
Since 1994, showerheads have been limited to a 2.5-gallon-per-minute (gpm) standard, and in 2013 this requirement was amended to ensure the 2.5-gpm standard applies to fixtures with more than one showerhead.
