After following the advice on these forum pages managed to successfully re-charge expansion vessel and now pressure level of heating system stabilised - Thanks for the guidance.
However since I did the above job there has been water dripping from the face of the pressure gauge. Do I need a new gauge? and if so what do I need to do to?
