When I turn on my domestic central heating there is an initial sound of a
surge of air bubbles in the area of the pump. There is a bleeder valve at a
height of about four feet over the pump. I find that when I leave the pump
running for 30 minutes or so I can switch off an then bleed a small amount
of air from this valve. I have frequently repeated this bleeding operation
each time releasing a small amount of air. My efforts seem to have little
effect on the air which appears to be accumulated round the pump.
Consequently the noise of the air can be heard coming from the area of the
pump. Can anyone advise me on the method of getting air from the system?
