MYSON Radiator Bleed Valve/Screw/Vent/Nipple Replacement

Product Information

There are a number of reasons why you need or want to replace your bleed valve but don’t worry, it is not a difficult task so keep reading and we will cover that shortly. We can do this by turning off the valves at each end – the first is the TRV (the one you use to turn the radiator temperature up/ down), and the other is known as the lockshield valve which usually requires a tool or lockshield key to open/ close. After doing this then the radiator should be isolated from the rest of the system, allowing you to remove the old bleed valve (carefully as there will still be a bit of pressure in the radiator) and screw in the new valve. Most of my radiators need bleeding at this time of year, a couple of them more than once, so that might mean a few openings.

With most common radiator designs, at the top of each end, there will be a plug inserted – one of them will be blank (smooth finish) and the other will have some kind of opening or fitting that can be opened with a tool or key – this one is the bleed valve. Now you will need to clean around openings, insert the plugs and do them up nice and tight letting the PTFE tape create the seal.Inevitably there will be some water escaping when you replace the bleed valve, so it is best to make sure that the water is cold enough to touch. If you have had to remove the bleed plug for any reason, you may be struggling to get a good and watertight seal. Note that 1/2" doesn't refer to any physical dimension of the part, but of the pipe that thread was originally used with. Our unique range of TRVs includes TRV2, including a Petite version, remote sensor heads, TRV bodies, an attractive decorative model, as well a specially designed TRV kits to complement our LST radiator range.

This is what it looks like in use, the vent in the picture is white, as it was fitted in the factory and then painted along with the radiator.

Bleed valves that have been painted do not look very appealing and once the radiators have been bled again, the paint will have cracked which probably defeats the object of painting it in the first place. TRVs are one of the most efficient ways of controlling the heat in your home and by installing TRVs you could save up to 40% on heating bills, as independently tested by the University of Salford. My part of Bristol's water comes form the Cotswolds and is rather harder than some of London's (I see you and the OP are both there, by your profiles) but we had plenty of limescale where I grew up in Greenwich. Getting the sludge out of that is a good few hours' work; fixing this valve would be a minor addition to the effort. This step is important to prevent leakage as new plugs alone will not be enough to prevent leakage so the threads will need to be wrapped with PTFE Tape.TBH though the scale is a smaller part of the problem than the sludge, at least since I got a condensing boiler a few years ago.
