The lone libertarian moderator on Fark linked up this bit of home-spun anarchy regarding how the government is regulating your bathroom:
... The Federal Energy Policy Act of 1992 mandates that "all faucet fixtures manufactured in the United States restrict maximum water flow at or below 2.5 gallons per minute (gpm) at 80 pounds per square inch (psi) of water pressure or 2.2 gpm at 60 psi."
Manufacturers must adhere to these regulations under penalty of law, and to be on the safe side, and adjust for high-water pressure systems, they typically undershoot. If you try your showers right now, you will probably find that they dispense water at 2 gallons per minute or even less. Together with other regulations concerning water pressure, your shower could fall to as low as 1.5 gallons per minute!
Warning: The following section is for information purposes only; I am not advocating egregious violations of federal law as some trouble-making rebel might. Do not endanger your status as a law-abiding citizen who takes wimpy showers.
We bought one of those fancy expensive "rainfall" showerheads when we moved into this house, which is when I learned about this. The thing came with convenient instructions on how to remove the blocker in question, but it wasn't that easy and I didn't want to screw up our new expensive showerhead. Two plus years later, I think it's time to take a screwdriver to it.
We also have to keep a plunger beside each toilet thanks to these regs. This in an area so well-served by water there's never been a burn ban or water conservation effort I've ever heard of.
But lord knows we gotta save the environment, so instead of using the market and local-level regulations to allow each region to handle their problems their own way, let's use the hundred-fifty pound sledge that is the federal government to solve the problem. Square pegs, meet round holes, and here comes the hammer.
