      I believe that I have an air lock in the pipes feeding and returning to my newly installed basement radiators. The radiators were installed in my newly remodeled basement to match my hot-water heating system (radiators) in the rest of the house (built 1929). The boiler has a pump. I think the problem is that both the boiler and new radiators sit below the feed and return pipes that travel in the ceiling. I’ve bled the air at the radiators, but it appears that I still have an air lock. Do I need to install bleeder valves in all the pipes at the highest level?

      Yes, this will provide a escape of air at the highest points in the system and should resolve this problem now and in the future.
