How to Fix a Kitchen Sink Leak

A leaky kitchen sink can be a frustrating and potentially costly problem. Fortunately, many sink leaks can be fixed with a few simple tools and techniques. This article will guide you through identifying the source of the leak, gathering the necessary materials, and performing the repair yourself.

Identifying the Source of the Leak

The first step in fixing a kitchen sink leak is determining its source. Carefully examine the area around the sink, paying attention to the following:

• Faucet Base: Look for drips or water pooling around the base of the faucet.
• Faucet Spout: Check the spout for drips or leaks, especially when the faucet is turned off.
• Faucet Handles: Inspect the handles for looseness or excessive movement. Leaks can occur if the handles are not properly secured.
• Supply Lines: Examine the water supply lines connecting to the faucet for leaks or corrosion.
• Sink Drain: Check the drain for leaks around the drain stopper, overflow plate, or the pipe itself.
• Underneath the Sink: Look for signs of water damage or leaks beneath the sink cabinet.

Note the location and type of leak to determine the most appropriate course of action.

Faucet leaks are common and can usually be repaired with a few simple steps.

1. Turn off the water supply to the faucet.
2. Remove the faucet handles. This is typically done by unscrewing a set screw located on the side or bottom of the handle.

1. Turn off the water supply to the sink.
2. Inspect the supply lines for leaks and corrosion. Replace any damaged or corroded lines.
3. Tighten any loose connections using a wrench.
4. If the leak persists, replace the entire supply line.
5. Turn the water supply back on and check for leaks.

Sink Drain Leaks

Sink drain leaks can occur around the drain stopper, the overflow plate, or the drain pipe itself. To fix a drain leak:

1. Turn off the water supply to the sink.
