To open a kitchen faucet, begin by locating the shut-off valve beneath the sink or near the wall. Turn it counterclockwise to stop water flow. Next, disassemble the handle by removing the decorative cap (if present) and unscrewing the retaining nut with a screwdriver. For some models, lifting the handle up or pulling it sideways releases the cartridge or stem. If the faucet is stuck, use pliers to gently twist the stem. Always test for residual water by opening the spout before reinstalling the handle.

The process ensures safe access to the faucet’s internal components without causing leaks or damage. According to the National Association of Home Builders (NAHB), 25% of U.S. homeowners encounter plumbing issues annually, often due to improper valve operation or disassembly. A 2021 study by the American Water Works Association found that 30% of faucet malfunctions result from failing to shut off the main water supply first, leading to water waste or property damage. Additionally, the Environmental Protection Agency (EPA) estimates that fixing leaks can reduce household water bills by up to 10%, emphasizing the importance of correct shut-off valve use. Proper technique minimizes repair costs and extends faucet lifespan, as corrosion or pressure damage accounts for 40% of replacement needs, per a 2023 report. Adhering to these steps aligns with industry standards for efficiency and safety, reducing the likelihood of costly errors.
