Hi,
Can anyone advise me please? I'm installing my own open-vented, Y-plan CH pipework and have just discovered I need to incorporate an automatic bypass valve circuit. As far as I understand it, it is just an ABV on 22mm tube at some point between the flow and return from the boiler. For convenience, I would like to put it after the pump between the mid-position valve inlet and the return from the cylinder. Would that be OK? If it is placed at the highest point, will I need to include an air vent in addition to the one on the 28mm cylinder inlet?
All help gratefully received.
Thanks
