Radiator Valve Change Kit

Product Information

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

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! 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. Then take the new thermostatic valve head and screw it onto the valve. You should be able to do this by hand.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. 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.
