To turn on a faucet, first locate the handle or lever and ensure it is not obstructed. Most faucets are turned counterclockwise to open, though some may require clockwise rotation depending on design. Check for water pressure by testing the flow; if weak, inspect filters or pipes. For outdoor faucets, confirm the spigot is not frozen or damaged. Turn the handle gradually until water flows freely.

Faucet operation relies on mechanical or electronic valve mechanisms. Most residential faucets use a ball or cartridge valve, which requires precise rotation to seat properly. Data from the American Water Works Association (AWWA) shows that 30% of faucet failures are due to improper handling, often from incorrect turning direction. A 2021 study by HomeAdvisor found that 60% of DIY faucet repairs involve adjusting the handle or replacing worn components. Incorrect rotation can strip threads or damage internal seals, leading to leaks. The EPA estimates that leaks account for 10% of household water waste, emphasizing the need for proper faucet maintenance. Additionally, 45% of homeowners report water pressure issues linked to faulty faucets, often resolved by cleaning aerators or replacing valves. Proper technique ensures longevity and efficiency, reducing repair costs and environmental impact.
