Hi, non combi system and 7 radiators. 1 radiator swapped with system drained. All back on but no water going to any radiator. Any ideas? The little tank has water in it and stays level even after the drain.
This often happens after a drain down to save time I get hose connect to outside tap and onto drain off point with a jubilee clip and shoot the system up with a blast of mains up its bum this usually gets things going QuickTime. if you over do it then water can come out of the overflow for the F and e tank ....the little one. Good luck
Thanks for the advice. Have had a plumber look at it and puts it down to a blocked T connector as the water level stays the same even when you have bleed valves and drainage open.
