How to remove airlock from water pipes: An airlock in your water pipes can cause frustrating disruptions, leading to weak or no water flow from your taps. Fortunately, removing an airlock is often a straightforward task that you can do yourself. In this guide, we’ll explain what an airlock is, how to identify it, and the steps you can take to fix the issue quickly.
What Is an Airlock in Water Pipes?
An airlock occurs when trapped air prevents water from flowing freely through your plumbing system. This is more common in hot water pipes and can lead to inconsistent or reduced water pressure. Left unresolved, an airlock can affect your entire water supply and cause ongoing issues with your plumbing.
Signs of an Airlock in Your Pipes
If you suspect an airlock, look out for these common signs:
- No water or weak flow from taps – Particularly from the hot water side.
- Sputtering taps – Water coming out in bursts instead of a steady stream.
- Gurgling noises – Air trapped in the pipes can create bubbling or gurgling sounds.
How to Remove an Airlock from Water Pipes
Here are a few simple methods to clear an airlock from your plumbing system:
Method 1: The Hosepipe Trick
This method uses water pressure to push the trapped air out of your system.
- Turn Off Your Taps – Ensure all taps in your home are off.
- Attach a Hosepipe – Connect a hose between a working cold water tap and the affected hot water tap.
- Turn On Both Taps – Open the cold tap first, then the hot tap. The cold water pressure should force the air out.
- Keep Running for a Few Minutes – Allow the water to flow for about 2-3 minutes.
- Turn Off the Taps – Close the hot tap first, then the cold tap. Remove the hose and test the hot tap.
Method 2: Running the Taps Alternately
- Turn On the Affected Tap – Let it run at a trickle.
- Turn On Another Tap – Open a tap at a lower level in your home to help push air out.
- Alternate Opening and Closing Taps – Doing this for a few minutes may help dislodge trapped air.
Method 3: Using a Plunger
For stubborn airlocks, a plunger may help:
- Partially Fill the Sink – This ensures a good seal.
- Place the Plunger Over the Tap Outlet – Ensure it covers the opening completely.
- Pump the Plunger – Repeatedly plunge to create pressure and dislodge the airlock.
- Test the Tap – If the water flows normally, the airlock is gone.
Preventing Future Airlocks
To reduce the risk of airlocks in your plumbing:
- Regularly run taps – Especially hot water taps.
- Maintain consistent water pressure – Check for leaks or system faults.
- Ensure professional installation – Poor plumbing work can contribute to recurring airlocks.
