Changing a radiator valve is a simple but effective solution to many common issues, and can be a quick fix for most styles and models, including electric radiators.
Read on to find out more about why it’s a good idea to change a radiator valve, and how to do it simply.
When you should check your radiator valves
One of the most common signs that your radiators are acting up is when you notice that they do not seem to heat up as well. One of the most common culprits behind this is that the existing valve is no longer working, and needs to be replaced.
Of course, that might not be the only reason why it’s time to check the valves on your radiators. Often, it may be that it’s time to update manual valves to easier to use thermostatic versions, or you might want to give them a style update, by replacing older, leaky models with a better fitting, newer one.
Whatever your reasons, changing your valves is much easier than you might expect.
Six steps to changing a valve
Before you get started with changing your radiator valves, make sure you have everything you need to hand. You’ll want a few pieces of plumbing equipment that can be easily found in a good DIY store or kit, including a hex key, adjustable spanner and a plumber’s wrench. You’ll also need a towel to wipe away any spilt water, a bucket or tub to contain any leaks, and a spare bit of hose. Finally, some PTFE can also be useful to fix any small leaks.
Next, make sure your heating system and water is completely turned off. You should also turn off electrical devices and thermostats in the area where you are planning to replace the valve.
Once you have done so, you’ll need to locate your drain off point. This is the lowest point in the house, and where you’ll be able to drain off water in the system. Using your piece of hose, open the drain cock and fix the hose in place. If the hose is quite tight, dipping the end in hot water can help soften the rubber a little, helping to attach it in place. Make sure the other end of the hose is outside, or in a large container, to collect excess water.
After the water has drained, you can remove the old valve, and will need to use the wrench, spanner or other tools, depending on how difficult it is to move. Before you can attach the new valve in place, clean the area thoroughly.
Finally, you can fix the new valve in place. This will vary for manual and thermostatic valves, so it’s best to check the specific instructions. You may want to use the PFTE tape around it to prevent leaks. After the area around the valve is secure and thoroughly checked, you are free to turn your water mains back on safely.
