Radiator Valve Change Kit

Product Information

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

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.

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

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