Faucet handles are the levers or knobs used to control the flow of water from a faucet. They allow users to turn the water on or off and adjust the temperature by mixing hot and cold water. Faucet handles come in various designs, materials, and finishes to match different styles of sinks and bathrooms. Typically, there are two types of faucet handles: single-handle and double-handle. A single-handle faucet has one lever that controls both temperature and flow, while a double-handle faucet has separate handles for hot and cold water. Proper installation and maintenance of faucet handles ensure efficient water usage and prevent leaks.
