: About 5 minutes per faucet

You can save another 500 gallons of water annually simply by replacing a standard aerator, which delivers more than 2.5 gallons per minute, with a low-flow one, with a flow of 0.5 to 1 gallon per minute. The low-flow aerators will cut water and energy usage while maintaining adequate water pressure.
Unsure whether your faucets are water wasters? Put a quart container under the sink faucet and let 'er flow. If the container fills in less than five seconds, get busy. In the kitchen you might want greater flow, say 2 to 4 gallons per minute, for filling a pot or the sink.
