I have a fully pumped heating system with a 'Y' valve.
The system has always generated air from somewhere, but no obvious leaks exist.
My thoughts are that the open air vent, which is situated immediately before the pump, is allowing air to be drawn into the pipework by the pump.
Has anyone any experience of that problem, and is the solution to position the vent after the pump i.e. on the pumped side, or will that present other problems?
