How You can Deal with Air lock in Pipes

Solving the Pesky Issue of Air Lock in Water Pipes: A Comprehensive Guide

Air lock in water pipes can be a frustrating problem for homeowners, causing disruptions to water flow and even rendering taps and faucets useless. This phenomenon, commonly known as an airlock, occurs when pockets of air become trapped within the water pipes, preventing the smooth flow of water. However, fear not, as there are several effective methods to tackle this issue and restore your water system to its optimal functionality.

Understanding Air Lock in Pipes:

Before delving into solutions, it’s essential to grasp the mechanics behind air lock in pipes. Typically, air enters the water pipes through various means, such as during repairs, renovations, or changes in water pressure. Once trapped, this air forms blockages within the pipes, impeding the flow of water and causing disruptions in the water supply to fixtures like taps, showers, and toilets.

Identifying Symptoms of Air Lock:

Recognizing the signs of air lock in pipes is crucial for prompt intervention. Common indicators include:

  1. Intermittent or reduced water flow from taps.
  2. Spluttering or spurting water.
  3. Complete cessation of water flow from certain fixtures.
  4. Gurgling noises emanating from the pipes when attempting to use water.
  5. Inconsistent water pressure throughout the plumbing system.

Now, let’s explore effective strategies for eliminating air lock in water pipes:

Bleeding the Air:

Bleeding the air from the affected water pipes is a fundamental method to alleviate air lock. Start by turning off the water supply to the affected area. Next, locate the highest tap in your property, usually found on the top floor or in an upper-level bathroom. Open this tap fully and allow it to run for several minutes. As air is lighter than water, it will naturally rise and escape through the open tap, effectively purging the airlock from the system.

Utilizing a Hose or Hosepipe:

For more stubborn airlocks, employing a hose or hosepipe can facilitate the removal of trapped air. Connect one end of the hose to the affected tap and immerse the other end in a bucket or basin filled with water. Turn on the tap and allow water to flow through the hose, creating a siphoning effect. This action helps dislodge and expel the trapped air, restoring normal water flow.

Re-pressurizing the System:

In cases where bleeding or using a hose proves ineffective, re-pressurizing the plumbing system can provide a solution. Shut off the main water supply to your property and open all taps, starting from the highest point and working your way down. Once all taps are open, turn the water supply back on. This process helps to equalize pressure within the pipes, dislodging any trapped air in the process.

Seeking Professional Assistance:

If DIY methods fail to resolve the issue, it may be time to enlist the expertise of a qualified plumber. Professional plumbers possess the knowledge, experience, and specialized equipment necessary to diagnose and rectify complex air lock problems efficiently. Additionally, they can inspect the entire plumbing system for any underlying issues contributing to the airlock and provide long-term solutions.


Dealing with air lock in water pipes can be a bothersome ordeal, disrupting the smooth functioning of your plumbing system. However, by understanding the causes and symptoms of air lock and employing the appropriate remedies such as bleeding the air, using a hose, re-pressurizing the system, or seeking professional assistance, you can effectively eliminate air lock issues and restore uninterrupted water flow throughout your property. Remember, timely intervention is key to preventing further complications and ensuring the longevity of your plumbing infrastructure.
