Hi, I have a radiator upstairs not working, I took it off and flushed it out in the garden till clean water came out, before I put it back I checked valves. The lock sheild side there is no water coming out and the Trv works on temperature, I think. So I used a wet/dry hoover to suck air lock out, but this never worked. I thought maybe the lock sheild was at fault so I started to drain the system and I noticed there was water coming out of it, put everything back and turned central heating back on .. no joy and no water coming out of lock sheild, any advice?
