Radiator Valve Change Kit

Product Information

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. Once the old thermostatic valve or manual is open, air will escape and water will flow out of the radiator. Since the radiator has been drained and refilled you will need to re-pressurise the system to ensure everything is working correctly. But before we start let’s have a look at why you might want to change your radiator valves in the first place!

Use a container underneath the valve to catch any drips but all of the water should have been drained from the radiator. 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. Please note:Our ‘How-To’ manuals are intended only as a guide to assist you with common home heating tasks.

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. If you are changing both radiator valves so you have a matching pair, now is the time to remove your old lockshield valve.

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.Note down the number of turns it took to turn the lockshield off as you will need to make the same number of turns when you connect the new lockshield and turn it back on. 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. Remember to open the lockshield valve the same number of turns as you noted down to allow water back into the radiator and turn the TRV to your desired number. Place a container beneath the valve and turn it anti-clockwise to open it using an adjustable spanner.
