I'm trying to repressurise my expansion vessel and although system pressure is showing zero and no more water is coming out of the rads, i still can't get any air to go in via the valve, just won't accept it, am i doing something wrong?
Also tried to release pressure using the pressure release valve (red knob), but this just clicks and at about 1/4 turn and doesn't appear to do anything, any thoughts?
