How to clear air lock in hot water tap
Is your hot water tap not working? Does it sputter and refuse to dispense warm water? It’s possible that your hot water tap has an air lock. Air locks occur when pockets of air get trapped in the water pipes, preventing the flow of water. The good news is that clearing an air lock is a relatively simple task that you can do yourself without the need for a plumber.
In order to clear an air lock in a hot water tap, you will need a few basic tools. First, locate the stopcock or isolation valve for your hot water supply and make sure it is in the open position. This is usually found near your hot water tank or boiler. You will also need a container to catch any water that may spray out during the process, as well as a towel or cloth to protect your hands.
To begin, turn off the electrical supply to your hot water system to ensure your safety. Then, locate the hot water tap that is affected by the air lock. Turn on the cold water tap to a slow but steady flow. This will help to release the air lock by forcing water through the pipes and displacing the trapped air. Keep the cold water tap running until a steady flow is established.
Next, slowly turn on the hot water tap, being prepared for water and air to spurt out initially. As the cold water continues to flow, the air lock should be forced out, allowing the hot water to flow freely. Keep the hot water tap running until a steady flow of hot water is established.
If clearing the air lock does not solve the problem, there may be another issue with your hot water system that requires professional attention. It’s always best to consult a qualified plumber in such cases in order to avoid further damage or complications. However, in many instances, a simple air lock can be quickly and easily resolved, restoring hot water to your taps.
What causes air lock in hot water taps?
An air lock in a hot water tap occurs when air becomes trapped in the pipes, preventing the smooth flow of hot water.
Possible causes of air lock:
1. Initial installation: During the installation of hot water pipes, air can become trapped within the system.
2. Loss of water pressure: If there is a sudden loss of water pressure in the hot water system, it can cause air to get trapped in the pipes.
3. Blockages: Blockages, such as scale or debris buildup, can disrupt the flow of hot water and lead to air becoming trapped.
Effects of air lock:
An air lock can prevent the hot water from flowing properly from the taps, resulting in reduced pressure or no water at all.
Additional effects of air lock may include gurgling or spluttering sounds coming from the tap, as well as small bursts of air escaping when the tap is turned on.
Resolving air lock:
1. Check the cold water supply: Ensure there is enough cold water supply to your hot water tank to eliminate air getting trapped at the outlet.
2. Bleed the system: Open the hot water taps in your property and let the water flow freely to remove the air lock. Starting from the tap nearest to your hot water cylinder and working your way towards the furthest tap may be necessary.
3. Seek professional help: If the air lock issue persists or if there are underlying problems with your hot water system, it is recommended to contact a qualified plumber to resolve the issue.

Understanding the air lock phenomenon and its effects
An air lock in a hot water tap occurs when air becomes trapped in the plumbing system, preventing the flow of water. This phenomenon can be frustrating and inconvenient, as it affects the functionality of the tap and hampers normal usage. Understanding why air locks happen and their effects is crucial in effectively clearing them and restoring water flow.
Causes of air lock in hot water taps:
Air locks can be caused by various factors in the plumbing system, including:
- Recent maintenance work: If any maintenance work has been carried out on the plumbing system, such as repairing a pipe or flushing the system, trapped air may find its way into the system.
- Changes in water pressure: Sudden changes in water pressure, either from the mains supply or due to usage in another part of the house, may cause air to enter the plumbing system and become trapped.
- System design flaws: Poorly designed plumbing systems may have areas where air can accumulate and cause blockages.
Effects of air lock:
The presence of an air lock can lead to several problems, including:
- No water flow: The most apparent effect is the absence of water flow from the affected hot water tap. This can be highly inconvenient, especially when the tap is essential for everyday activities such as washing dishes or taking a shower.
- Strange noises: Air trapped within the plumbing system can result in gurgling or bubbling sounds when attempting to use the affected tap. This can be a clear indicator of an air lock issue.
- Reduced efficiency: An air lock can affect the overall efficiency of the plumbing system and the effectiveness of water-based appliances that rely on a steady flow of hot water. The lack of water flow also wastes energy as the water heater remains idle.
In conclusion, understanding the causes and effects of air locks in hot water taps is important in resolving this plumbing issue. By identifying the root cause of the air lock and taking appropriate action, such as bleeding the affected tap or seeking professional assistance, users can restore normal water flow and prevent further recurrence.
Proven methods to clear air lock in hot water taps
Experiencing a disrupted flow of hot water from your tap can be quite frustrating. In many cases, this is due to an air lock in the hot water pipe. However, the good news is that there are proven methods you can use to clear the air lock and restore the steady flow of hot water. Here are a few effective techniques you can try:
1. Bleeding the radiator: Start by locating the radiator nearest to the affected tap. Turn off the heating system and then proceed to bleed the radiator using a bleed key or a screwdriver. This process will release any trapped air and create a smoother flow of hot water.
2. Using a hosepipe: If bleeding the radiator did not resolve the issue, you can try using a hosepipe. Connect one end of the hosepipe to a cold-water tap and the other end to the hot water tap that appears to have the air lock. Turn on both taps simultaneously and the pressure from the cold water should dislodge the trapped air in the hot water pipe.
3. Hot water cylinder valve: Another method is to check the valve on the hot water cylinder. If the valve is partially closed, it can cause air to become trapped. Ensure the valve is fully open to allow the proper flow of hot water.
4. Lifting and replacing the float valve: In some cases, the issue might be with the float valve in the hot water tank. If the valve is stuck in a closed position, it can cause air locks. Try lifting and replacing the float valve a few times to dislodge any trapped air.
5. Seeking professional help: If none of the above methods work, it might be time to call a professional plumber. They have the knowledge and tools to diagnose and fix any complex hot water issues.
Remember, safety should always be a priority when working with hot water systems. Before attempting any of these methods, make sure to consult the manufacturer’s instructions or seek professional advice if needed. With a little patience and the right approach, you’ll be able to clear the air lock in your hot water tap and enjoy a steady flow of hot water once again.
Tips and Tricks to Restore Proper Water Flow
If you are experiencing an airlock in your hot water tap, don’t worry! Here are some tips and tricks to help you restore proper water flow:
- Bleed the air out: Start by turning off the hot water tap affected by the airlock. Then, locate the nearby bleed valve, typically found under the sink. Open the valve slowly using a screwdriver or a pair of pliers. This will release any trapped air and allow water to flow freely.
- Check other taps: If bleeding the air doesn’t resolve the issue, check other hot water taps in your home. If they are also experiencing low water flow, there might be an issue with the water supply system. In such cases, it’s best to contact a professional plumber for further assistance.
- Faucet aerator cleaning: If water flow is still weak after bleeding the air, the aerator might be clogged with sediment and minerals. Unscrew the aerator at the spout using pliers and clean it with a solution of vinegar and water. Rinse thoroughly and reattach it to the tap. This should improve water flow and pressure.
- Pipe blockage: If only one specific tap is experiencing low water flow, there might be a blockage in the pipes leading to the tap. Attempt cleaning the pipes by disconnecting them at the nearest joint and flushing them with water. You can use a pipe snake or a wire brush to remove any obstructions. Reconnect the pipes and test the water flow again.
- Professional assistance: If all else fails, it’s advisable to call a professional plumber. They will have the expertise and tools to locate and fix any issues causing the airlock and restore proper water flow. This will ensure that your hot water taps work efficiently and effectively.
By following these tips and tricks, you should be able to resolve and clear the airlock in your hot water tap, restoring a proper water flow for your convenience.
