Learning how to repressurise a Worcester boiler is a valuable skill that can assist you in diagnosing various issues that may arise when your appliance starts to act up.
Low pressure is a common indication of a fault in your heating system, typically caused by a leak in a pipe or joint. By following a few simple steps, you can easily address this problem and restore the proper water pressure to your boiler.
Steps to stop up your Worcester Boiler water pressure
- Locate your filling loop key – most modern Worcester boilers have a white plastic key that can be inserted into the bottom of the appliance.
- Insert key into manifold – You will notice a black plastic manifold next to a white plastic nut. This is where you will insert the filling key. Before doing this, ensure the boiler is switched off.
- Now turn the white nut – It is essential to avoid turning it all the way to the maximum level in one go. Instead, gradually increase the pressure to reach the required level.
- Keep an eye on the pressure gauge – making sure you don’t pressurise it too much.
Here’s a great video from the manufacturer to help understand the steps visually.
What happens if you over-pressurise the boiler
If you happen to open the white plastic nut too far, the boiler pressure will exceed the recommended level. In such cases, you can easily reduce the pressure by using a radiator key or an adjustable spanner.
Start by obtaining a jug or container to capture the water that will be released. This task may require two people, with one person monitoring the boiler gauge to ensure it doesn’t fall below the recommended pressure.
o reduce the pressure, slowly bleed the radiator by opening the valve using the radiator key or adjustable spanner. As the air is released from the radiator, the pressure will decrease. Make sure to monitor the pressure gauge closely until it returns to the appropriate level.
