After removing the plugs there will be a bit of air in the system that should make it to the AAV although now would be a good time to make sure all of the radiators are bled. Conclusion A leaking bleed valve can cause havoc in the pressurised system and will need rectifying sooner rather than later. You could try removing the bleed plug and attempting to reseal but, in most cases, it is best to just buy a new one. Aesthetics Keep the valve open until the water stops flowing out although if you are unable to open the bleed valve, move on to step 4. Step 4 – Remove the Bleed Plug

Our DECORATIVE range includes 8 different products with compression or push fit connections in 10mm and 15mm sizes Bleed plugs can often be removed when a system needs draining or the radiator needs flushing and may be due to age, wear and tear or poor technique, you may end up struggling. How to Replace Radiator Bleed Valves No, all radiator bleed valves are not the same size. Although many radiators use a standard size, you may find that designer radiators will have a different design. First, we need to turn off the heating system and let it cool. 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. Step 2 – Isolate the Radiator in Question They’re typically placed at the top of the radiator because any air that will be trapped inside will be forced upwards by the pressurised water below.You will want to take your new plugs and wrap the PTFE tape around the threads, pressing the tape into the grooves as you go. How many times you wrap the thread will depend on the valve, but 3 times around is a good benchmark.

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. Why do Radiator Bleed Valves Need Replacing?MYSON Controls produce a wide range of thermostatic radiator valves (TRVs) to suit any application, from standard domestic requirements to polished decorative products.
