The Department of Energy has settled a civil penalty action it initiated against "Showerheadpower" for the manufacture and online sale of showerheads that used more water than allowed by federal law. As enacted by Congress, showerheads may not consume water in excess of 2.5 gallons per minute. The manufacturer in this matter admitted it had altered commercially available, legal showerheads to consume water in excess of this efficiency standard. The manufacturer admitted to selling at least 5,000 of these modified showerheads between June 3, 2006, and February 7, 2011.
