Leaky faucets are a common home plumbing issue. While these problems are often easy to fix, a professional may be needed if the faucet fixtures themselves are damaged. The primary culprits behind leaky faucets are usually the O-rings. These small components can become bent, broken, or worn down, causing the valves to malfunction and resulting in leaks. Regular maintenance and timely replacement of worn-out O-rings can help prevent leaks and ensure your faucet operates smoothly.
