Radiator Valve Change Kit

Product Information

Tighten the nuts by hand for speed then finish off with the adjustable spanner. Make sure it’s not too tight or you might damage the thread! However, changing a radiator valve without draining the system is probably not a job for the first-time DIYer so it would be best to get the professionals in. Turn the heating off and allow the radiators to cool completely for at least an hour. You should do this before starting any job to do with your radiators to avoid burning yourself! If you think the task of trying to avoid flooding the room whilst changing your radiator valve is too much to handle, there is an alternative method to do the job without draining the system. But, you will need some extra tools to help you. In this case, the size of the radiator valve refers to the size of the valve connection and pipework instead of the design of the valve.

But don’t worry if your pipes are slightly bigger or smaller than the standard 15mm. Sometimes copper pipes can be anything between 8mm – 28mm depending on where they are in your home and the age of the building. The standard size of copper pipework is 15mm and all of our radiator valves have a half inch (½”) thread on the bottom (the part that connects the valve to the pipe) which makes them suitable for use with 15mm piping. Making the swap to thermostatic radiator valves can help heat your home more efficiently, reduce heating bills and give you more control over the temperature so that each room feels comfortable. To do this, hold the body of the valve with the grips and use an adjustable spanner to make an upwards turn and unscrew the cap nut until water starts to flow out.So if you find a pair of valves you like the look of but they aren’t the right size for your pipework, you may need to buy radiator reducers or adapters from any plumbing or DIY merchant to ensure a clean connection. If you consider yourself an experienced DIYer and feel confident with most radiator related jobs then you should find it fairly easy to change a radiator valve if you have a combi boiler system.

There are a couple of things to do after you have changed your radiator valve to make sure that the heating system is working properly. Finally, if you have any concerns and don’t feel confident changing the valves yourself, you can always rely on a gas safe registered engineer to get the job done for you. Now you need to remove any trapped air inside the radiator. This is called bleeding the radiator. There may also be air trapped in the nearest radiator, so it is best to bleed that one too.We hope you have found this guide helpful and at this point you have a lovely new pair of valves on your radiator! If you decide you want to change your radiator or need to remove a radiator from the wall for decorating, watch this video to help! Cover the floor area around the radiator under the valves you are going to replace with the towels and container to catch any excess water. Most radiators have two radiator valves that connect the radiator to the pipes and allow hot water to enter the radiator and control how much heat is given out.
