Install faucet aerators to increase pressure and reduce flow
Faucets are responsible for approximately 15% of indoor household water use (according to the U.S. Environmental Protection Agency). Aerators are small devices that attach to the faucet to reduce water flow. They often make the flow more forceful, giving you more effective wetting and rinsing.
A faucet aerator can reduce water flow to 0.5-2 gallons per minute (gpm). You can easily determine your current water flow by placing an empty one-quart container under your faucet and timing how long it takes to fill. If it takes less than five seconds, your faucet uses more than 3 gpm. If it takes ten seconds, your faucet uses 1.5 gpm.
