You may wish to change a radaitor valve for a number of reason, either due to the age or look or maybe due to a failed or sease valve.
Here are the general steps to change and replace a radiator valve:
- Turn off the heating system: Before starting any work on the radiator, turn off the heating system to avoid the risk of burns from hot water or steam.
- Drain the radiator: Use a radiator key to open the bleed valve at the top of the radiator and let the water drain into a bucket or bowl. This will lower the water level in the radiator and prevent spillage when you remove the valve.
- Remove the old valve: Use a wrench to loosen and remove the old valve from the radiator. If the valve is stuck, you may need to apply some penetrating oil and use a little force to loosen it.
- Clean the threads: Use a wire brush or emery cloth to clean the threads on the radiator where the new valve will be attached.
- Install the new valve: Apply some PTFE tape to the threads of the new valve, then screw it onto the radiator by hand. Use a wrench to tighten the valve securely but do not over-tighten it, as this can damage the threads.
- Re-fill the radiator: Close the bleed valve at the top of the radiator and open the valve at the bottom to let the water back into the radiator. Be sure to monitor the water level and top up as necessary.
- Test the new valve: Turn on the heating system and check the new valve for leaks. If you notice any leaks, tighten the valve slightly or apply more PTFE tape.
- Bleed the radiator: Once the radiator is fully filled, use the bleed key to open the bleed valve and let out any air trapped in the system. Close the valve when water starts to come out.
- Clean up: Wipe down any spills or drips, and dispose of any old parts or tools.
Note: These are general instructions and the specific steps may vary depending on the type of radiator valve and heating system you have. It’s always a good idea to consult a professional if you are unsure about any aspect of the installation.
