Step 1 · Shut Off Water Supply

Before starting any work, you must shut off the water to the faucet. Look for two small valves, one for the hot water line and one for the cold, located in the cabinet directly beneath the sink. Turn the handles of both valves clockwise until they are fully closed. If you cannot find these local shutoff valves, you will need to turn off the main water supply valve for the entire house. Once the valves are closed, turn on both faucet handles to release any trapped water and pressure in the lines until the water stops flowing completely.
