: Steam heat system, house, 3 floors, separate return pipes. 4 rads on 1st floor. The rad that normally gets hot last on first floor now stays cold even when the upstairs rads heat up. Took valve off, blew through, seemed clear. Replaced with a new No. 6 valve just in case. When no valve on the rad, works fine, steam blows out hole. But upon replacing old or new valve in hole, rad stops working. Important to fix because thermostat in this room. Ideas?
