hi again, try it with a good adjustable spanner, and give it a bang with the palm of your hand in a anti clockwise direction, or somthing a bit "harder" if you dont want to hurt your hand, get a MAN to do it for you
Thanks go to Bucks 51. I got an adjustable spanner, banged it a few times with my hand and finally managed to get it to turn. Lo and Behold I now have a hot radiator. Thanks for the help and advice. much appreciated.
that's a new one!! never knew banging an ajdustable would help open a nut/spindle/valve! Might have to try that in future if a tap headgear nut is stiff and won't budge! I suppose it shocks it out of position and loosens it?
