Faucets

Bathroom and kitchen faucets account for 16% of the water used in an average home.  Federal Plumbing Standards now specify that kitchen faucets use no more than 2.5 gpm and bathroom faucets use no more than 2.2 gpm, though several use less quite effectively.

Installing an aerator - the screw-on tip of the faucet - can be one of the most cost-effective water conservation measures your household can do because they control the flow of water through your faucet.

This is especially true if your faucets are older and don't have aerators, since some older models can use 5 or more gallons per minute (gpm).   

Many water providers give low-flow aerators out to their customers for free, or you can purchase one at most home improvement stores for about $1-5.00 each.
