This is what I have done:
I took a radiator off the wall to replaster the room. It was in 8mm microbore. I extended the pipes so I could run them under the floor, rather than clipped along the skirting, by cutting them with a pipe cutter and using two compression fittings. After having nearly been scalded I put the radiator back on the wall, tightened up the two end fittings and opened the valves. I let the air out of the bleed valve until water came out. All the other rads are hot. This one is cold. But the flow pipe is hot right up to the rad.
So what have I done wrong? I suspect that I may have crossed over the flow and return pipes when I reconnected. But would this be a problem? Of the two rad valves, one can be opened by hand and the other has a cap which is removed and is opened with a spanner. It is this one which is hottest. Should I have it the other way round, or is there some other problem? Any replies appreciated!
