I have renewed all the O rings in the radiator valves, put one new valve on, I am now trying to refill the system but only 3 of the radiators have filled with water the rest are not filling (that is 6 in total not filling). They are old radiators but we never had a problem before now. Any ideas
all radiators not filling up

I`ll cut to the chase...........fill the system thru` a hose from an outside tap to the drain cock that you used to drain it
