Install efficient bathroom-faucet aerators

Lavatory faucets don't need as much water as kitchen faucets.
Kitchen faucets usually need to deliver fairly close to the allowable 2.5 gallons per minute (gpmGallons per minute. Measure of liquid (usually water) flow.) of water to fill large pots, for example, but bathroom faucets often do not. In many homes, 1.0 gpm or even 0.5 gpm is adequate for washing hands, brushing teeth, or shaving. A simple screw-on aerator will reduce flow to the desired level. Aerators are inexpensive and can easily be swapped out later if the flow rate seems higher or lower than expected.
