I have an open type gas central heating system. With the heating on, the pipe before and after the pump are hot there is a 90 degree bend( with a bleed valve) after which the pipe is cold. This is the first time the heating has been "on" since last winter, the hot water is and has been fine. I have bleed all radiators no differeance, I drained the system then refilled and re bled still no differance. This happened (or something similar) a couple of years ago and the guys said an air lock and put in the bled valve at the 90 degree bend. Any ideas? Thanks
