The answer to 'why is my faucet burst pipe' is that a burst pipe is usually caused by freezing temperatures, high water pressure, or a worn-out washer. Symptoms include water leaking from the faucet or the surrounding area, low water pressure, or the faucet not turning on at all. Solutions may involve replacing the faucet, repairing the pipe, or adjusting the water pressure.
If the burst pipe is in an easily accessible area, you may be able to fix it yourself with basic plumbing tools and supplies. However, if the pipe is behind a wall or in a hard-to-reach location, or if you're not comfortable making plumbing repairs, it's best to call a professional plumber to diagnose and fix the issue.
