Step-by-Step Guide to Fixing a Sink Pipe Leak

Turn Off the Water Supply

Before starting any repair, locate the water shut-off valves under your sink and turn them off. This prevents more water from leaking while you work.

Drain the Pipes

Place a bucket under the pipe to catch any remaining water in the pipes. Open the faucet to release any trapped water.

Inspect the Pipes

Carefully examine the pipes to identify the source of the leak. Look for obvious signs of wear, corrosion, or loose connections.

Tighten Loose Connections

If you find any loose connections, use an adjustable wrench to tighten them. Sometimes, this simple step is all it takes to stop the leak.

Replace Worn-Out Washers

If the leak is coming from a joint, the washer may be worn out. Remove the old washer and replace it with a new one, ensuring it fits securely.

Use Pipe Tape

For threaded connections, wrap pipe tape around the threads before reconnecting. This helps create a watertight seal.

Address Corroded Pipes

If your pipes are corroded, you may need to replace the section of the pipe that’s affected. Use a pipe cutter to remove the damaged segment and replace it with a new piece.

Preventing Future Leaks

Regular Inspections

Conduct regular inspections of your plumbing system to catch potential issues before they become significant problems.

Proper Maintenance

Maintain your plumbing by using sink strainers to prevent clogs, and avoid pouring grease or other harmful substances down the drain.

Upgrading Your Plumbing

Consider upgrading old and corroded pipes with newer, more durable materials such as PVC or PEX.

When to Call a Professional

If your attempts to fix the leak are unsuccessful, or if the problem is beyond your expertise, it may be time to call a professional plumber. They have the tools and knowledge to handle complex plumbing issues.
