How to Clear an Airlock in Your Water Pipes: A Practical Guide

Airlocks in your plumbing system can cause frustrating problems like reduced water flow or sudden stops in water supply. These occur when air becomes trapped inside your pipes, interrupting the normal flow of water. Fortunately, many airlocks can be fixed quickly without needing a plumber. This guide explains how to identify and remove airlocks yourself, saving you time and money.

Recognizing an Airlock in Your Plumbing

Before attempting to fix the problem, it’s important to confirm that an airlock is causing your water issues. Look out for these common symptoms:

• Low Water Pressure: If your taps or showerheads have noticeably weaker flow, trapped air may be the culprit.

• Water Spluttering or Gurgling: Irregular water flow accompanied by noises or bursts can indicate air pockets in the pipes.

• No Water Flow at All: In severe cases, an airlock may completely block water from reaching certain taps or fixtures.

What You’ll Need to Get Started

• Bucket

• Towels

• Adjustable wrench

• Pliers

• Screwdriver

• Hose (optional, for flushing)

Step-by-Step Instructions to Remove an Airlock

1. Shut Off the Main Water Supply
   Locate the main valve, usually near your water meter or where water enters your building, and turn it off to prevent water from flowing during the process.

2. Find the Problematic Tap
   Identify which tap or fixture is affected by the airlock symptoms.

3. Open the Affected Tap Fully
   Turn the tap handle completely on to allow any trapped pressure to escape once you start clearing the airlock.

4. Gather Your Tools Nearby
   Have all your equipment ready so the process goes smoothly.

5. Locate the Airlock Site
   Inspect pipework close to the affected fixture, especially bends and high points where air tends to accumulate.

6. Release the Airlock
   Carefully loosen the nut on the pipe joint where you suspect the airlock is trapped. Air and water will escape — keep loosening gently until the flow stabilizes and hissing stops.

7. Check the Water Flow
   Watch the tap to ensure water is running steadily and without interruption or bubbles.

8. Tighten the Nut Securely
   Once the airlock has been cleared, firmly tighten the nut to avoid leaks.

9. Turn the Water Supply Back On
   Open the main valve and test the tap to confirm normal water flow is restored.

10. Inspect Other Fixtures
    Check other taps to make sure no additional airlocks remain.

Tips to Prevent Future Airlocks

• Schedule regular plumbing checks and maintenance.

• Ensure professional installation of pipes to reduce trapped air risks.

• Avoid turning taps on and off abruptly.

• Flush your plumbing system occasionally to clear sediment and prevent blockages.

A dripping or outdated tap can be annoying and waste a surprising amount of water over time. Fortunately, replacing a tap is a straightforward job that many homeowners can tackle themselves — with the right tools, preparation, and care.

In this guide, DM Emergency Plumbing walks you through the process of replacing a tap safely and efficiently, while sharing expert tips to help you avoid common mistakes.

When Should You Replace a Tap?

You might need to replace a tap if you notice:

• Constant dripping, even after tightening

• Corrosion or rust around the base

• Difficulty turning the handles

• Water leaking from the tap body or joints

• A desire to upgrade your bathroom or kitchen fixtures

If these sound familiar, it’s time for a replacement.

Tools and Materials You’ll Need

Before you start, make sure you have the right tools on hand:

• New tap (make sure it matches your sink or basin type)

• Adjustable wrench

• Basin wrench (for hard-to-reach areas)

• Plumber’s tape (Teflon tape)

• Towels or cloths

• Bucket

• Cleaning cloth

Step-by-Step: How to Replace a Tap

1. Turn Off the Water Supply

Start by switching off your water supply. You’ll usually find isolation valves under the sink — turn them clockwise to stop the water flow. If you can’t find them, shut off your main water valve. Then, open the old tap to release any remaining water in the pipes.

2. Prepare the Area

Place towels or a bucket underneath the sink to catch any drips. Keep your tools nearby for easy access.

3. Remove the Old Tap

Using an adjustable wrench or basin wrench, loosen the nuts securing the old tap to the sink. Disconnect the water supply pipes carefully. Once everything is loosened, lift out the old tap from the sink or basin.

4. Clean the Mounting Surface

Before fitting the new tap, clean the area where the old one sat. Remove any limescale, old sealant, or dirt to ensure a smooth and watertight installation.

5. Fit the New Tap

Insert the new tap into the mounting holes. Align it correctly, then tighten the fixing nuts underneath to hold it securely in place. Follow the manufacturer’s instructions for your specific tap model.

6. Connect the Water Supply

Attach the flexible hoses or water supply lines to the new tap’s inlets. Use plumber’s tape on threaded connections to prevent leaks. Tighten gently but firmly — avoid over-tightening, which can damage fittings.

7. Turn On the Water Supply

Once everything is connected, slowly turn the water supply back on. Check for leaks around the connections and tighten slightly if needed.

8. Test the Tap

Run both hot and cold water for a few minutes to flush out air and debris. Ensure smooth water flow and that there are no leaks under the sink.

Pro Tips from DM Emergency Plumbing

• Always double-check that the new tap fits your existing sink holes and plumbing connections.

• If your tap is old or corroded, fittings may be difficult to loosen — don’t force them; use penetrating oil or call a professional.

• For mixer taps, pay close attention to hot and cold water connections to avoid cross-connections.
