Radiator Valve Change Kit

Product Information

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. When all the water has drained from the radiator, keep unscrewing the nut until you can pull the valve out of the radiator to disconnect it. Just like designer radiators have become much better looking over time, there’s now a stylish selection of radiator valves to choose from to suit your home decor.

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. Once the old thermostatic valve or manual is open, air will escape and water will flow out of the radiator. Use a large container or wet and dry vacuum to catch the water that flows out of the radiator until there is no water left inside. This could take about 5-10 minutes or longer depending on the size of your radiator. Updating your radiator valves can have many benefits on your home heating and your home decor. Here’s why: 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.

It is important to keep hold of the valve body with the grips to avoid it putting pressure on the pipe causing it to bend and potentially leak later on! 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.So whether you love the large, decorative, traditional valves or the small minimalist options, all our valves have industry standard connections. Since radiator valves play a significant part in how well central heating radiators operate, and as most of them are visibly on show in our homes, changing your radiator valves is a great way to improve the performance, efficiency and overall look of your heating 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. 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!

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. But if you only want to change your thermostatic or manual valve then you can skip to the final maintenance section. 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. Then take the new thermostatic valve head and screw it onto the valve. You should be able to do this by hand. 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.Holding the valve body with the grips, align it with the adapter and tighten the cap nut with the spanner that holds them together. Then tighten the cap nut that holds the valve to the pipe.

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. However, if you are only updating one radiator you can change the radiator valve without fully draining the system and there are actually benefits of doing so. If you are swapping an old thermostatic valve for a new TRV, take the thermostatic head off both valves. You should be able to turn this to remove it by hand.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. Use a container underneath the valve to catch any drips but all of the water should have been drained from the radiator.
