6 Ways to Fix a Leaking Pipe Joint

Have you ever had a pipe joint spring a leak? A problem like that requires a speedy fix. Unfortunately, you may not have the necessary supplies or knowledge to do a proper repair.

If you have found yourself in this predicament, then you know it can be a frustrating experience. But don’t worry. There are many ways to fix a leaking pipe joint.

In this blog post, we’ll show you how to do a leaking pipe joint repair so that you can take care of the problem and move forward with your day.

Let’s get started!

What is a Pipe Joint?

First off, you may be wondering if the leak you’ve found in your pipe is actually at a pipe joint. A pipe joint is simply the point where two pipes are connected.

There are many different types of pipe joints, and each one has its own unique function.

Here are just a few of the different types:

1. Socket or Coupler Joint

The most common type of pipe joint is the coupling. A threaded coupling socket is used to connect two pipes of the same diameter by screwing them together.

2. Union Joint

Another type of pipe joint is the union. A union is used to connect two pipes that may need to be assembled and disassembled with ease and without disruption to the horizontal flow of the pipe. It is usually used on pipe parts like valves and water meters.

3. Elbow Joint


An elbow joint is used to make a turn in the pipe, which will change the flow’s direction. These joints can be classified as 45-degree, 90-degree, and 180-degree turns. An elbow joint is often used in drainage systems where pipes need to change directions quickly.

4. Tee Joint

A tee joint is used to connect three pipes together, forming a T shape. This type of joint is often used in irrigation systems and water supply lines, in both commercial and industrial applications.

5. Flanged Joint

A flanged joint is used to connect pipes by a metal or plastic ring that sits between the two pipes. This kind of joint is really helpful when pipes must pass through walls or the ceiling, and it also works for drain pipes.

6. Compression Joint

A compression joint is a threaded ring used to join two pipes using compression instead of something like soldering. It is sometimes used in low-pressure applications of plumbing or electrical conduit systems.

How Does a Pipe Joint Spring a Leak?

A pipe joint can spring a leak for many reasons.

One of the most common reasons is corrosion. Corrosion can occur when the pipe joint is exposed to water or moisture. This can cause the pipes to rust and deteriorate over time.

Another reason for a leaking pipe joint is loose threads. If the pipes are not properly tightened, they can become loose and allow water to leak through the opening.

There are many other reasons why a pipe joint may leak, but these are the most common.

Now that you know how a pipe joint can leak, let’s take a look at the supplies you will need to fix the problem.


Supplies You Will Need

The supplies you use will depend on the process you use to fix the leak. Here is a list of optional supplies:

How to Fix a Leaking Pipe Joint

No matter the reason for your leaky pipe, there are some quick and easy ways to fix the problem until you can get a permanent solution. Let’s look at a few handy methods.

First Step: Turn Off The Water

Before you begin fixing a leaky pipe joint, you will want to turn off the water main supply so that you can make any necessary repairs. Some repair methods require you to disassemble the piping, so you won’t want water gushing out while you’re trying to fix the problem.

You will also want to examine the joint to make sure you understand what kind of joint it is. There may be more appropriate methods than others for fixing the joint leak, depending on what type it is.

Once the water is turned off and you have examined the joint, you can begin your repairs.

Method 1: Tighten the Loose Fitting

If your leak is due to a loose fitting, then the first thing you’ll want to do is try to tighten it. Use a pipe wrench or an adjustable wrench to tighten the pipes until they are snug.

If the pipes are still leaking, then you may need to use a sealant to fix the problem, which we will explore in the methods below.

Method 2: Fix the Pipe with Plumber’s Tape

The second method to try is plumber’s tape. Plumber’s tape is a type of thread sealant that can be used on pipes to prevent leaks.

To use this method, simply wrap the plumber’s tape around the threads of the pipe joint that is leaking. Wrap the tape in a clockwise direction so that it will tighten as you go. Once you have wrapped the entire joint, use a wrench to tighten it further. This should stop the leak temporarily.

Method 3: Use Epoxy Putty

Another quick and easy way to fix a leaking pipe joint is with epoxy putty. Epoxy putty is a type of repair compound that can be used to fill cracks and pinhole leaks in pipes. It is designed to harden at room temperature.

To use epoxy putty, simply knead the putty until it’s pliable and then press it into the leaky area. Use a putty knife to smooth it out and then allow it to harden. Once the epoxy putty has hardened, it will create a watertight seal that will temporarily fix the leak.

Method 4: Use a Fiberglass Wrap

If you’re looking for a more permanent solution, you may want to try using a fiberglass wrap. A fiberglass wrap is a type of repair tape that is infused with resin.

To use this method, simply cut a piece of the fiberglass wrap to size and then apply it over the leaky hole or crack, wrapping it around the pipe. Apply water, which will activate the resin, causing the wrap to harden like steel and create a watertight seal.

Method 5: Wrap on Self-Fusing Silicone Tape


If you’re looking for an easy way to fix a leaky pipe, you may want to try self-fusing silicone tape. This type of repair tape is designed to adhere to itself, creating a watertight seal. Not only does it adhere to itself, but it actually chemically bonds to itself–a process that is called self-amalgamating.

To use self-fusing silicone tape, simply wrap the tape around the pipe joint that is leaking. Be sure to wrap it tightly so that it creates a good seal. The tape will automatically fuse to itself and keep the pipe from leaking. This is still considered a temporary fix, however, and works best on low-pressure systems.

Method 6: Apply a Patch and Clamp

If you have a wide pipe that needs fixing, the best way to fix it might be to patch it with a rubber pad and a couple of hose clamps. This method is often used as a temporary fix until you can get a more permanent solution.

To use this method, simply clean the area around the leaky pipe and then dry it off. Cut a piece of rubber that is large enough to cover the hole or crack and then place it over the leak. Secure the rubber in place with a hose clamp on either side.

Call a Professional Plumber if Necessary


As mentioned, most of the methods here are temporary fixes. Therefore, no matter what repair method you use, it’s important to set up a permanent fix as well. This means that you will still want to contact a professional plumber at some point.

Also, even after the plumber comes and fixes the leak, be sure to keep an eye on the questionable pipe joint for a while, just to be sure there aren’t any future leaks.

If you do notice any more leaks, call the plumber again for another repair. It can feel frustrating to have to call a professional each time you have a leak, but you don’t want to let a leaky pipe continue to drip. Trying to fix the joint yourself can be risky, too, so sometimes it is best to leave it to the professionals.

In Conclusion

There you have it! Now you understand more about how to fix a leaking pipe joint! If you have any questions, feel free to contact a professional plumber. They will be able to help you identify the source of the leak and recommend the best repair method for your particular situation.
