  3. Place a container underneath the valve: Place a suitable container, such as a bucket, beneath the valve to catch any water that may spill out.

  4. Open the drain valve: Use a wrench or spanner to open the drain valve. Turn the valve anti-clockwise until water starts to flow out.

  5. Let the water drain out: Allow the water to drain out completely. This may take a few minutes, depending on the size of the radiator.

  6. Close the drain valve: Once all the water has drained out, close the drain valve by turning it clockwise with a wrench or spanner.

  7. Refill the radiator: Refill the radiator with water using a suitable filling loop or a hose. Make sure to top up the pressure by checking the pressure gauge on your boiler.

  8. Bleed the radiator: Once you have refilled the radiator, bleed it to remove any air trapped inside. This can be done using a radiator key or a flat screwdriver.

By following these steps, you can drain your radiator safely and efficiently.
