Are you facing the frustrating issue of airlocks in your pipes disrupting the flow of hot water or affecting the efficiency of your central heating system? In this blog post we will explore the common occurrences of airlocks in household pipes and provide you with practical methods to resolve them.
Whether you need to tackle airlocks in your hot water system or clear airlocks from your central heating, we’ve got you covered. Keep reading for expert advice, step-by-step instructions, and answers to frequently asked questions to help you maintain a smooth-running plumbing system.
Additionally, we will address important queries such as how to prevent airlocks in pipes and the potential risks associated with bleeding radiators. Let’s dive in and empower you with the knowledge and skills to keep your pipes clear and your systems running smoothly.
What happens?
When you get an airlock in a pipe, the air trapped in the central heating or hot water system stops circulation, causing radiators to stop heating up and hot water taps to stop running.
This airlock can occur due to various causes, such as air pockets in the pipes or incorrect installation of the system.
The consequences of an airlock can be frustrating, as it disrupts the normal functioning of your central heating or hot water system.
It is important to address this issue promptly to restore the proper flow of hot water and heat to your home.
Methods for Hot Water
To restore hot water flow in your system, you can release trapped air by either using a hose pipe and tape to connect the hot and cold taps or by turning off the water supply, opening all taps, and then turning them on again. Here are three things you can try to remove an airlock in your hot water system:
A. Connect the hose pipe to both the hot and cold taps and then open both taps to allow the cold water to force through the hot.
B: Turn off the water supply and open all taps in your house.
C.Turn on the hot water taps first, one by one, starting from the lowest point in your system.
Common causes of trapped air in hot water systems include recent plumbing work or a drop in water pressure. It is important to release trapped air as it can lead to decreased hot water flow.
However, there are potential dangers such as scalding and water damage if the process is not done correctly. Always exercise caution and consider seeking professional help if unsure.
Method for Central Heating
If your radiators are not heating up or only heating from the bottom, this indicates that there may be trapped air in your central heating system. Don’t worry, though, because there’s a simple solution: radiator bleeding.
Bleeding your radiators is a method used to release the trapped air and restore proper heating. Here’s how you can do it yourself.
First, turn on your heating system and identify the radiators that are not working. Next, turn off the heating to allow the radiators to cool down. Once they’re cool, locate the radiator bleed valve, usually found at the top or side.
With a radiator bleed key, slowly open the valve until you hear a hissing sound. This is the trapped air escaping. Once the hissing stops and water starts to flow, close the valve. Repeat this process for each radiator that needs bleeding.
You can reduce the air in your heating system permanently by adding a deaerator, there is a huge benefit to doing this as it will also reduce corrosion on your system. The Spirotech Spirovent is perfect for this, and the also do a version with a filter as well called the SpiroCombi.
Frequently Asked Questions
How can I prevent airlocks in my pipes from occurring in the first place?
To prevent airlocks in your pipes, you can take preventive measures such as regular maintenance. This includes ensuring proper water flow, checking for leaks or blockages, and properly bleeding radiators. These maintenance tips will help prevent airlocks from occurring in the first place.
Are there any risks involved in bleeding radiators to clear airlocks from the central heating system?
To prevent airlocks in pipes, bleeding radiators in the central heating system is an effective solution. While there are minimal risks involved, such as potential water leakage or burns, following proper safety precautions can help mitigate these risks.
