    I replaced shut off valves on half the radiators in the house. After system start up bled air from all. They seemed to heat properly. Now I have one that gets luke warm on discharge side only, while the radiator gets warm on top, cold at bottom. Does not appear to be air bound as I get water immediately. Any ideas or suggestions greatly appreciated.
