To turn on a faucet, locate the handle or lever and gently lift or press it until water flows. For dual-lever faucets, ensure both handles are in the "on" position. If the faucet is electronic, press the button or touchpad. Always check for water pressure and clear any debris blocking the aerator.

Correct faucet operation is critical to prevent water waste and ensure efficiency. The U.S. Environmental Protection Agency (EPA) reports that 10% of households in the country have leaks, collectively wasting over 1 billion gallons of water annually. Properly turning on a faucet reduces the risk of leaks caused by misaligned handles or faulty mechanisms. Additionally, the EPA’s WaterSense program highlights that fixing a single dripping faucet can save up to 3,000 gallons of water per year, equivalent to the annual usage of one person. Modern faucets with aerators also conserve water by mixing air with water, reducing flow rates by 30% without compromising pressure. Studies show that 20% of residential water waste stems from leaks, emphasizing the need for regular maintenance and correct usage. By following proper faucet operation guidelines, households can lower utility bills, protect plumbing systems, and contribute to broader water conservation efforts.
