How to Fix a Leaky Pipe Under Your Kitchen Sink: A Step-by-Step Guide

Before you dive into any repairs, it’s crucial to identify the source of the leak. There are three main culprits: a loose connection, a corroded or cracked pipe, or a worn-out washer or O-ring.

Identifying the Source of the Leak

Loose Connection: This is usually found where the pipe joins to the faucet or the sink itself. You’ll likely see water dripping from this area.
Corroded or Cracked Pipe: A visible crack or signs of corrosion on the pipe are clear indicators of a problem.
Worn-out Washer or O-ring: These parts can wear down over time, leading to leaks. You might see water dripping from the faucet itself, even when it’s turned off.

Once you know what’s causing the leak, you can gather the necessary tools.

Gathering Your Tools

The tools you need will depend on the type of leak and the type of pipe you have. Here’s a general list:

Wrench: For tightening or loosening nuts and fittings.
Pliers: For gripping pipes or other parts.
Screwdriver: For removing or securing screws.
Pipe Cutter: For cutting pipes, if needed.
Solder Iron: For soldering copper pipes, if applicable.
Pipe Glue: For securing PVC pipes, if applicable.
Teflon Tape: For sealing threaded connections.
Replacement Parts: Washers, O-rings, fittings, or pipe sections, as needed.

Turning Off the Water Supply

Before you start any repairs, turn off the water supply to the sink. This is a vital safety step.

Locate the Shut-Off Valve: The shut-off valve is usually located under the sink, close to the supply lines.
Turn the Valve Clockwise: Turn the valve clockwise until it stops. This will shut off the water flow to the sink.

Fixing a Leaky Connection

If the leak is caused by a loose connection, you can try tightening it.

Compression Nut: If the connection uses a compression nut, use a wrench to tighten it. Be careful not to overtighten, as this can damage the pipe.
Slip Nut: If the connection uses a slip nut, tighten it with a wrench.
Replacing a Cracked or Corroded Connection: If the connection is cracked or corroded, you’ll need to replace it. This is usually a simple process of removing the old fitting and installing a new one.

Replacing a Worn-out Washer or O-ring

If the leak is caused by a worn-out washer or O-ring, you’ll need to disassemble the faucet and replace the faulty part.

Disassembly: Carefully disassemble the faucet following the manufacturer’s instructions. You might need to remove the handle, spout, or other parts.
Replacement: Locate the worn-out washer or O-ring and replace it with a new one.
Reassembly: Reassemble the faucet, making sure all parts are properly seated and tightened.

Repairing a Cracked or Corroded Pipe

If the pipe itself is cracked or corroded, you’ll need to cut out the damaged section and replace it with a new one.

Cutting: Use a pipe cutter to cut out the damaged section.
Connecting: Connect the remaining sections of pipe using appropriate fittings.
Securing: Secure the fitting using pipe glue, solder, or compression nuts depending on the pipe material.

Testing for Leaks

Once you’ve completed your repairs, turn the water supply back on and carefully check for leaks. If you see any leaks, you’ll need to re-evaluate your work and make any necessary adjustments.

Preventing Future Leaks

Regular Inspection: Inspect the pipes under your sink for signs of corrosion, leaks, or damage.
Tighten Loose Connections: Tighten any loose connections to prevent leaks.
Replace Worn-out Parts: Replace washers, O-rings, and other parts before they wear down and cause leaks.
Protect Pipes from Extreme Temperatures: Ensure your pipes are insulated during cold weather to prevent freezing and damage.

When to Call a Professional

While many plumbing repairs can be tackled by homeowners, there are times when it’s best to call a professional.

Complex Repairs: If you’re dealing with a complex leak or have concerns about your plumbing, it’s best to consult a professional.
Safety Concerns: If you’re unsure about the safety of any repair, don’t hesitate to call a plumber.
