The other day I became aware of a "funny noise" emanating from the hall radiator. After a careful listen I realised that the squeaking/whistling noise was coming from one of the bleed screws (its a double-panel rad). I tried to tighten it up, but it was already fully tightened. Realising that air was getting into the CH system, I closed the rad valves, removed the screw, and wound some PTFE tape round its threads before refitting.
This solved the problem for a day, but yesterday I ended up repeating the process with a larger amount of PTFE. So.....can anyone advise me as to an appropriate sealing compound or such like that I can apply to the bleed screw to make a proper repair? I realise that some epoxy would certainly do (if it would survive the heat), but would render that bleed screw useless. I am thinking along the lines of a thread-lock or something, as the leak is clearly very small.
Unless of course, this is completely the wrong idea and I need a new radiator?
Thanks,
James.
