Can some one help please.....two plumbers in, no fix!
The furthest upstairs radiator from the boiler keeps getting air in it. Now here's the puzzling bit. When I open the wee valve at the top to bleed the air out nothing happens. If I turn the TVR to closed and wait, then air will start to come out very slowly. Leave it for a bit and then turn the TVR up to 5 and the air will start rushing out. Sometimes though I feel that air is being sucked IN to the wee valve at the top when I open it up. However the rad stills keeps gradually filling up with air and has to bled every couple of weeks. I've had two plumbers come in and scratch their heads, they haven't been able to find out how air is getting into the system. Any suggestions?
