Thanks. Good information. I played musical air valves, however there are still two radiators,one upstairs and one down, at the end of the main having trouble getting steam and toward the end of the cycle there are gurgling sounds in those pipes. This is a one pipe system with condensate returns off the mains. A hanger was loose on that end of the main, but I didn't know if the end of the main should pitch toward or away from the boiler. I pitched it away from the boiler thinking the steam would move the condensate toward the returns. Any more suggestions?
