The answer to 'why is my faucet frozen' is that the faucet has likely frozen due to cold outdoor temperatures. When the temperature drops below freezing, the water inside the faucet can freeze, causing the faucet to become stuck and unable to turn on or off. This is a common issue during the winter months, especially for outdoor faucets that are exposed to the elements.
Some common symptoms of a frozen faucet include the faucet handle being difficult or impossible to turn, no water coming out when the faucet is turned on, and potential leaks or water damage around the faucet. To fix a frozen faucet, you can try warming the faucet with a hair dryer or space heater to thaw the ice, or you may need to insulate the faucet or shut off the water supply to prevent future freezing.
