    The bleed valve is screwed in fully but the little hole underneath still leaks water, so i assume it needs replacing the only problem is is that it will not budge. i have tried every spanner, wrench and mole grips i have but it will not shift!
    Can anyone give me some ideas to try and remove it?
    Heat does not work either

    many thanks

    You state that you have tried the application of heat to try and budge the
    vent valve body. ? Have you attempted this procedure with the radiator empty? If not, have a go at that and let us know how you get on.

    Greetings,
    How about filing a couple of "flats" on the rounded off hexagon,applying heat until cherry red and then trying again .If this fails i don,t really see an alternative to drilling and re-tapping the vent valve.
