The problem:

Every sink comes with an aerator installed – its what allows the water to come out in a confined manner, rather than spraying all over the sink. Unfortunately, most faucets come with an aerator that allows 2.2 gallons per minute. A standard shower (which you’ve already converted to low-flow!) uses 2.5 gallons per minute. That means your bathroom sink is putting out almost as much water as your shower! While you may need more than a gallon of water to wash your entire body, you do not need that much water to wash your hands and face, shave, or brush your teeth.

The solution:

Faucet aerators are the 3 dollar solution – simply go to your nearest hardware store and purchase a 1 gpm or even better 0.5 gpm aerator, bring it to your home or office, unscrew the existing one, and replace it with the low-flow version. Instant water savings, over 50% (or 75% with 0.5 gpm versions) for less than 3 bucks and 3 minutes of your time. Replacing faucet aerators is the easiest and most cost effective mechanism that each and every one of us can do in our homes and places of employment.
