Radiator Valve Change Kit

Product Information

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! Since the radiator has been drained and refilled you will need to re-pressurise the system to ensure everything is working correctly. 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. 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. 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.

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! 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. A very useful kit which comprises of 2 patented rubber bungs, key pattern fixing clip and a radiator bleed key and is used for changing radiator valves without draining down the system. It is suitable for use on 15mm and 22mm pipework and is supplied in a strong nylon bag.

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 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.

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! So whether you love the large, decorative, traditional valves or the small minimalist options, all our valves have industry standard connections.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.

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. Updating your radiator valves can have many benefits on your home heating and your home decor. Here’s why: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. 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! 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. Use a container underneath the valve to catch any drips but all of the water should have been drained from the radiator.

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.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. But if you only want to change your thermostatic or manual valve then you can skip to the final maintenance section. 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.
