Somehow, amid the myriad of important issues and crisis in the world, were talking about showerheads and water pressure. While speaking at the White House in July, Trump said:So showerheads you take a shower, the water doesnt come out. Since first enacted in 1992, federal law has dictated that new showerheads shouldnt pour more than 2.5 gallons of water per minute. Since these water savings will reduce demands on water heaters, they will also save energy. Some of the new low flow heads are rated at even lower flow rates, such as 1.8 or 1.5 gpm, saving significantly more water.
