I have read the correspondance on banging steam radiators (reference Loretta Chilcoat 11/27/00). I have the exact same problem and have tried the solution of putting a wedge underneath one side of the radiator so that the water will drain out. But the banging is getting louder. I don't think that I can tilt the radiator any more as I am afraid of breaking any connections. Is there anyting else that I can do?
