A leaking kitchen faucet is not just an annoyance; it can also lead to higher water bills and potential water damage if left unchecked. Whether it’s a slow drip or a steady stream, fixing a leaking faucet is a task that most homeowners can tackle with the right tools and a bit of patience. In this guide, we’ll walk you through the steps to repair a leaking kitchen faucet, identify common causes, and provide tips to prevent future leaks.Common Causes of a Leaking Kitchen FaucetBefore diving into repairs, it’s helpful to understand why your faucet might be leaking. Here are some common culprits:

• Worn-out washers or O-rings: Over time, the rubber washers or O-rings inside the faucet can degrade, causing leaks.
• Corroded valve seat: The valve seat connects the faucet and the spout. If it becomes corroded, water can seep through.
• Loose parts: The handle or other components may have loosened over time, leading to leaks.
• High water pressure: Excessive water pressure can strain the faucet’s internal mechanisms, causing leaks.
