When a pipe starts leaking in your home, it’s easy to panic. 

However, with the right tools and a little know-how, you can quickly fix a leaking pipe yourself. 

At GES London, we have been providing plumbing services for years, so we’re here to walk you through the process like a pro. 

Don’t worry, by the end of this guide, you’ll feel confident and prepared to tackle that leak.

1. Turn Off the Water Supply

The first and most important step when dealing with a leaking pipe is turning off the water supply. 

You don’t want to risk further damage or flooding while trying to fix the pipe.

• Find your main water shut-off valve, usually located near the water meter or where the pipe enters your home.
• Turn it off to stop the flow of water and prevent more from leaking out.

2. Assess the Damage

Before you rush into fixing the pipe, take a moment to inspect the damage. 

You’ll need to know exactly where the leak is coming from and how bad it is. Here’s how to assess the situation:

• Look for visible cracks or holes on the pipe.
• Check the surrounding area for wet spots or drips.
• If the leak is small, a simple fix may be all you need. If it’s a larger issue, it’s best to call in a professional.

3. Gather the Necessary Tools and Materials

Now that the water is off and you’ve identified the leak, it’s time to gather the tools you’ll need to fix it. Here’s a quick list:

• Pipe repair tape or plumbing putty (for small leaks)
• Pipe cutter (if the pipe needs to be replaced)
• PVC pipe and fittings (for PVC pipes)
• Adjustable wrench or plumber’s wrench (for tightening connections)
• Bucket or towel to catch any remaining water

4. Temporary Fix with Pipe Repair Tape (For Small Leaks)

If you’re dealing with a small leak, you can use pipe repair tape as a temporary fix. 

Here’s how to do it:

1. Clean the area around the leak with a rag to remove any dirt or moisture.
2. Wrap the pipe repair tape around the leak, covering it entirely.
3. Press it tightly to make sure the tape sticks and seals the leak.

This method will hold you over until you can replace or permanently fix the pipe.

5. Use Epoxy Putty for a Stronger Seal

For a stronger seal on a more stubborn leak, epoxy putty is your best friend. Here’s how to use it:

1. Mix the epoxy putty according to the instructions on the package.
2. Apply the putty to the leak, covering it thoroughly.
3. Allow the putty to cure, usually for about 30 minutes to an hour, before turning the water back on.

This fix can last longer, but it’s still a temporary solution until you can replace the damaged pipe.

6. Replace the Damaged Pipe (For Severe Leaks)

If the pipe is severely damaged or cracked, a replacement is necessary. 

Here’s how to replace a pipe:

1. Turn off the water supply again (if you haven’t already).
2. Cut the damaged section of the pipe using a pipe cutter.
3. Measure and cut the replacement pipe to match the length of the section you removed.
4. Attach the new pipe by using the appropriate fittings and connecting them tightly.
5. Seal the joints with pipe joint compound or Teflon tape for added security.
6. Turn the water back on and check for leaks.

7. Test for Leaks

Once you’ve made the necessary repairs, it’s time to test the pipe to ensure everything is working properly:

• Turn the water supply back on slowly.
• Inspect the repaired area for any signs of leaking.
• If you notice any further leaks, it’s best to tighten the connections or add more sealing material.

8. When to Call a Professional Plumber

While many homeowners can tackle simple leaks themselves, some situations call for professional help. 

Here are a few cases where it’s best to call a plumber:

• The leak is too large or severe to fix with basic tools.
• You’re unsure about how to replace the pipe properly.
• You’re dealing with complex plumbing systems, like gas pipes.

Plumbers have the expertise and equipment to quickly diagnose and fix problems, saving you time and stress in the long run.
