Step-by-Step Guide to Flushing Your Radiators
1. Turn off your heating system and allow the radiators to cool completely.
2. Lay down towels or absorbent material around the radiator to protect your flooring from any spills.
3. Close the lockshield valve, typically located at the opposite end of the radiator from the control valve.
4. Attach a hose to the drain valve, which is usually found at the bottom corner of the radiator. Make sure the other end of the hose is positioned in a suitable container or outdoors to collect the water.
5. Open the drain valve and allow the water to flow out of the radiator. Once the water flow has stopped, close the drain valve.
6. Use a radiator key or flathead screwdriver to open the bleed valve at the top of the radiator, allowing air to enter and facilitate the flushing process.
7. Open the lockshield valve and allow water to flow into the radiator, displacing any remaining debris and sludge. You may need to open and close the drain valve several times to ensure all the debris is removed.
8. Once the water runs clear, close the drain valve and remove the hose.
9. Open both the lockshield and control valves, then bleed the radiator to remove any trapped air.
10. Turn your heating system back on and check all radiators for proper function and heat distribution. If necessary, adjust the balance of your radiators to ensure even heating throughout your home.
