What is an airlock in pipes?

An airlock in pipes refers to the situation where air becomes trapped in a section of the plumbing system, preventing water from flowing through it. The trapped air creates a blockage that interrupts the smooth flow of water, leading to a host of problems that affect the performance of your plumbing system.

What causes an airlock in pipes?

There are several reasons why airlock in pipes can occur. The most common causes include:

  • Poor installation of pipes: If your pipes are not installed correctly, air can become trapped inside them, leading to an airlock.
  • Leaks in pipes: If there is a leak in your plumbing system, air can enter and become trapped inside the pipes.
  • Changes in water pressure: Sudden changes in water pressure can cause air to become trapped in pipes, leading to an airlock.
  • Empty pipes: If your pipes are empty, for example, after a repair or maintenance work, air can enter and become trapped inside.

What are the symptoms of an airlock in pipes?

The following are some common symptoms of an airlock in pipes:

  • No water coming out of the tap
  • Low water pressure
  • Gurgling sounds coming from pipes
  • Uneven water flow
  • Sputtering tap
  • Banging noises in the pipes

If you notice any of these symptoms, it’s essential to address the issue promptly to prevent further damage to your plumbing system.

Solutions for airlock in pipes:

Now that we know what an airlock in pipes is and what causes it, let’s look at some effective solutions to fix the problem.

  1. Turn off the water supply:

The first step in fixing an airlock in pipes is to turn off the water supply. This step is crucial to prevent water from flowing and causing further damage to the plumbing system.

  1. Locate the affected pipe:

Next, you need to locate the pipe where the airlock has occurred. This can be done by checking the pipes for leaks or by listening for gurgling sounds coming from them.

  1. Bleed the affected pipe:

To remove the airlock, you need to bleed the affected pipe. To do this, turn on the tap closest to the airlock and let the water flow until it runs smoothly. This process will force the trapped air out of the pipe, restoring normal water flow.

  1. Repeat the process:

If the first attempt doesn’t work, repeat the process by turning off the water supply, locating the affected pipe, and bleeding it again. It may take several attempts to remove the airlock entirely.


  1. Can airlock in pipes cause damage to my plumbing system?

Yes, airlock in pipes can cause damage to your plumbing system if left unaddressed. The trapped air can cause pressure build-up, which can lead to leaks or bursts in the pipes.

  1. How can I prevent airlock in pipes?

To prevent airlock in pipes, there are several things you can do:

  • Proper installation: Make sure that your pipes are installed correctly, and all air is removed before water is allowed to flow through them.
  • Regular maintenance: Schedule regular maintenance checks to identify and fix any potential leaks or issues with your plumbing system.
  • Avoid sudden changes in water pressure: Try to avoid sudden changes in water pressure, as this can cause air to become trapped in pipes.
  • Keep pipes full of water: Always ensure that your pipes are full of water to prevent air from entering and becoming trapped.
  1. Can I fix an airlock in pipes myself?

Yes, you can fix an airlock in pipes yourself by following the steps outlined in the solutions section. However, if you’re unsure or uncomfortable working with your plumbing system, it’s best to call a professional plumber for assistance.
