Radiator Valve Change Kit

Product Information

Grip the TRV and start unscrewing the nut that connects it to the radiator. Don't take it all the way off yet. Just loosen it for now. As the temperatures start to fall, having the best valves on your radiators becomes really important. You might want to change the valves to alter the look of your radiator, improve performance with a TRV or simply replace a leaking valve. In this guide we will take you through the simple steps you need to follow to remove your radiator valve and replace it with a new one. How To Change A Radiator Valve: Now you want to add a bit of jointing compound to each joint. Jointing compound is a sealand that helps to seal threaded pipes. 5. Fit the new valve

If you have a combi boiler then you could drain it yourself. Take a look at our How to Drain a Combi Boiler for help doing this. For anyone with a combi boiler, the method of draining the system is relatively easy. If your home has a conventional cylinder tank, it can be a lot more difficult to drain the system and this is where we recommend calling in a professional. 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. Once you're confident your heating system has been drained completely, you'll need to undo the two nuts connecting the valve to the radiator. The control valve is normally either manual or thermostatic. And when replacing radiator valves, these are the ones we're talking about.

When to Change a Radiator Valve

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. When changing your radiator valves or replacing a manual valve with a new TRV, prepare the right tools and equipment you may need to carry out your task. We’ve gathered a small list for you: Lay a towel under the valve you'll be changing. This will just stop the floor from getting wet if there's a spillage. Radiator valve sizing is the diameter of the connection and pipework. Rather than the height of the valve.

Next you'll need to open the bleed valves on all the radiators in your home to stop anymore water flowing into your radiators and help more water drain out. Opening these valves can also stop any other radiators in your system retaining water which could be released later on. 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. 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. 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 your heating system is gravity fed, you can now turn on the water supply in the same place you switched it off earlier. Once you've done this the radiators in your home should begin to fill up with water. As this happens, it's a good idea to keep an eye on your new valve and the other radiators in your home in case of any leaks.Then take the new thermostatic valve head and screw it onto the valve. You should be able to do this by hand. Since the radiator has been drained and refilled you will need to re-pressurise the system to ensure everything is working correctly. Work in a clean area, having a towel or a cloth handy will enable you to keep the area and floors dry and safe for any job Unscrew the cap and take off the radiator valve . If you’re not sure how to do it , follow these guidelines: firstly, place some dry towels, sheets or cloths under the valve to catch any dripping water that may be left over after draining and bleeding your radiator. Next, hold the body of the old valve with a wrench while you use an adjustable spanner to unscrew the nuts. Unscrew the cap nuts and remove the body of the valve from the radiator. Use wire wool to clean away excess gunk that may have accumulated on it. Step 5. How to Fit Your New Radiator Valve

Choose from classic white or chrome dial designs to match your towel rails and radiators. Manual radiator valves are simple to fit, easy to use, and come in multiple sizes. We have a range of manual radiator valves in styles to suit any home, from contemporary square angled chrome to a traditional crosshead or smooth finish valve. Position the valve over the pipe then tighten each of the nuts by hand. Now grab your wrench and grips and tighten both nuts up using the same method as when you removed them. But if you only want to change your thermostatic or manual valve then you can skip to the final maintenance section. 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. Once you’re happy that the radiator and valve isn’t leaking open up the bleed valve to let out any air that may be trapped inside the radiator. This air will prevent the water from filling the radiator.Whatever reason you have for replacing your radiator valveswe’ll guide you through the process in 6 easy steps. We’ll also show you how to change a radiator valve as well as explaining how to drain the system. Step 4: Make up the valve, ensuring the retaining nut and olive are on the pipe. Position the new valve body suitably angled/aligned for your radiator's tails and hand-tighten the connections. Tighten everything up using a suitable pair of grips or wrenches, and ensure the valve is actually closed. Knowing how to use your new radiator control valves properly could help to keep your heating bills down. 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.

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. 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. The last step is to bleed all of your radiators. This will ensure they're all properly filled and there's no air trapped in the system. When refilling and bleeding your system, we'd recommend adding inhibitor to keep your radiators working at their best. This means the numbers on a thermostatic radiator valve refer to room temperature. Not the temperature of the radiator. An easy mistake to make. 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!

How does a radiator valve work?

A thermostatic radiator valve can save you quite a lot of money each year in heating bills and is certainly advised for most households.
