President Trump’s executive order seeks to repeal a previous administration’s definition of “showerhead” in the Federal Register, which was approximately 13,000 words long and included detailed instructions on how showers should operate. The order is effective 30 days from publication of the notice in the Federal Register, and it directs the Secretary of Energy to publish a notice rescinding the previous definition of “showerhead”. According to the White House website, this action was taken to maintain acceptable water pressure in showerheads, which are a common piece of hardware.
