Cold radiator.
Posted by Josh on July 11, 2003 at 19:21:21:
I have a hot water heating sytem with large cast iron radiators. They all get hot but one on the second floor. I've drained the system and ran a snake down the cold radiator to the basement. I've even put radiator and boiler cleaner in the sytem and neither things have worked. The system is full and all the radiators have been bled I still have that one radiator on the second floor that is cold. What can I do?
