Maybe somebody can help me regarding cast iron radiators. When I open the bleeder screw to the bleed the radiator, should air come first then water, or should just air come out with no water. So many people have given me different advice I do not know who to believe anymore. My impression is that radiator might be plugged, if that is the case can they be unplugged. Any info would be helpful, thanks.
