Water system not working as it should? It could be an airlock. This common issue disrupts the flow of water, leaving homeowners frustrated and unsure of what to do next. The good news? Fixing an airlock doesn’t always require a plumber. With some know-how and basic tools, you can often resolve the issue yourself.
In this guide, we’ll explain what an airlock is, how to identify it, and how to tackle it yourself in a few simple steps. We’ll also highlight when it’s best to call in a professional plumber.
What is an airlock in water pipes?
An airlock occurs when air becomes trapped in a section of your water pipes, preventing water from flowing freely. This commonly happens in a hot water system but can also occur in cold water systems. Think of it as a bubble of air stubbornly blocking your water’s path.
Airlocks are typically caused by:
- Incorrectly functioning plumbing systems
- High points in pipework where air naturally accumulates
- Recent repairs or modifications to your water system
If left unresolved, an airlock in pipes can impact water pressure and disrupt your home’s water supply.
Signs of an airlock in your home’s water system
Not quite sure whether you’re dealing with an airlock? Here are the tell-tale signs to look out for:
- Strange noises: Gurgling or sputtering sounds when turning on taps
- Low water pressure: A noticeable reduction in water flow, particularly in hot water taps
- Interruption in water flow: Water coming through inconsistently or failing to flow altogether
- Water only flowing in certain areas: For example, one tap works fine while another barely trickles
If any of these sound familiar, your water pipes may be suffering from an airlock.
DIY solution: step-by-step guide to removing airlocks
Before calling in a plumber, you can try a DIY solution to remove the airlock in your water pipes. Follow the steps below and get your water system flowing smoothly again. This method can be used to clear a suspected air block in cold and hot water pipes/hot water outlet.
Step 1: Turn off the water supply
Safety first! Locate your home’s main water supply valve (often found near the water meter or stopcock) and turn it off. This prevents water from gushing out when you work on the pipes.
Step 2: Connect taps with a garden hose pipe
You’ll need a garden hose or similar flexible tubing for this step.
- Attach one end of the hose securely to a working tap that has strong water pressure (a cold water tap will generally work better than a hot tap, but both hot and cold taps can be used for this step).
- Fix the other end to the affected tap. Ensure both connections are tight to avoid any leaks.
Step 3: Force the air out
Now for the clever bit!
- Turn on the working tap to full pressure, allowing water to flow through the hose into the affected tap.
- The strong flow from the functioning tap forces water (and the trapped air) out of the problem pipe.
- After a minute or two, turn off both taps.
Step 4: Check your water flow
Remove the hose and turn on the previously affected tap. If you’ve successfully cleared the airlock, you should see a smooth flow of water.
Step 5 (optional): Bleed the system
If water flow issues persist, you may need to take bleeding your entire system a step further. Start by turning on all the taps in your home at full blast, beginning with the lowest taps and working your way to the highest. Leave them running for five to ten minutes to flush out trapped air.
When to call a professional plumber
While DIY methods can work wonders, there are times when airlock removal requires professional expertise from a plumber or qualified heating engineer.
Signs that DIY may not be enough
- You’ve followed the DIY steps, but water flow is still inconsistent
- You hear loud banging or hammering noises in your pipes
- Airlocks occur frequently, indicating a larger underlying issue
- You’re unsure how to safely handle the problem without specialist tools

FAQ
Can an airlock or air bubbles in my water pipes affect my central heating system?
Yes, airlocks and trapped air bubbles can disrupt the flow of water in your central heating system. This can result in inconsistent heating, cold spots in radiators, or a complete lack of heat.
Can an airlock fix itself over time?
In some cases, small airlocks may work themselves out over time as water flows through the pipes. However, it’s best to take action and remove the airlock yourself or call a professional plumber to prevent any potential long-term issues with your water system.
How can I prevent future airlocks in my water system?
Regularly checking and maintaining your plumbing system can help prevent future occurrences of airlocks. This includes making sure all pipes are properly insulated, looking out for high points where air can get trapped, and addressing any repairs or modifications promptly. Additionally, it’s important to have your plumbing system professionally inspected on a regular basis to catch and address any potential issues before they become bigger problems.
What should I do if I suspect an airlock but don’t feel comfortable attempting the DIY solution?
If you’re unsure about tackling an airlock yourself, it’s always best to call in a professional plumber. Attempting to fix the problem without proper knowledge and tools can lead to further damage or safety hazards. Trusting a qualified expert will ensure the issue is resolved safely and effectively.
