Radiator Valve Change Kit

Product Information

If you're new to DIY, we'd recommend keeping the fittings from your existing valve. However, if you're not happy with the way the existing nuts look or the setup isn't compatible with the new valve, you will need to change the radiator insert. 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.

Step 3: Remove the old radiator valve and clean up the pipe end. Ensure you have bare copper where the valve's olive will seal. 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. 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.Firstly, if you're changing manual radiator valves then you should upgrade to thermostatic radiator valves. You may also be looking to upgrade the control valves. Replacing manual valves with thermostatic valves can give you far more control and help to lower your heating bills. 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 Changing a radiator valve can be a DIY job but we strongly advise getting a professional in. Will the heating system need to be drained?

Fit the body of the TRV to the radiator and pipe. Use the wrench to tighten the nuts right up on each side. Now you can simply screw the head of the TRV onto the body. 6. Close the bleed valves 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! 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. Take your radiator bleed key and fit it to the bleed valve. You can then turn the key and open the valve fully.

Then unscrew and remove the nut connecting the TRV to the pipe beneath the radiator. Once that's done, you can remove the nut you loosened earlier. 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. 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! The great thing about thermostatic radiator valves is they're able to detect the temperature in the room. Manual radiator valves can't do this.

Before you can start removing your radiator valves you'll first need to remove all water from your central heating system. Although some people claim you don't need to do this, it's always a good idea as it can prevent any water leakage should something go wrong.Actually, fitting radiator valves or a thermostatic one is not that difficult. Position your new valve in the right place. Align the valve cap-nut and sealing components over the end of the pipe and attach the new valve, while being careful not to tighten the cap-nut too early. Using your wrench, align the valve with the adaptor and follow this by tightening the cap-nut that joins them together. Now, ensure you tighten the cap-nut that holds the valve to the water pipe. You can manually fit the TRV onto the valve. Once you complete those actions, you’re ready to proceed to the next step. Step 6. Turn On Your Water Supply and Bleed the Radiator Once More Before we change the radiator valve we’ll first need to isolate the water supply. When we shut off the water it’ll no longer enter the boiler and this could cause it to overheat and burn out the pumps so we’ll also need to switch of the heating system too! Your radiator should now be heating up and working perfectly if it wasn’t before. If you replaced the radiator valve because the old one was outdated or worn then I’m sure you’ll be pleased with your new, shiny valves. Now we're going to explain how to fit a radiator valve - manual and trv valves. Whichever one you're fitting should be covered.

Updating your radiator valves can have many benefits on your home heating and your home decor. Here’s why: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. Once they’re tight (but not overly done) remove the protective cap from the top of the valve body - this is usually screwed on so simply unscrew it. Now take the top of the valve and connect it to the valve body. Once it’s on you’ll want to just gently tighten up the nut a little, be careful not to over tighten it. If you're using tools to tighten up nuts then you could use a bit of cloth so that the finish of the valve isn't damaged in anyway. If you still experience any issues, such as cold patches and visible leaks, then consider removing your radiator and replacing it altogether. Takeaways This method is perfect for combi boiler systems, but if you have a conventional system (conventional cylinder tank system) you’ll require help from a registered heating engineer. 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
