Hi all, I have a y plan gravity fed heating system, in the airing cupboard there is your normal setup, heating pump 3 port valve ect. However I have noticed this gate valve on the system and have always wondered what it is and what it does. I will describe it best I can without a picture, so here goes, Just after the pump in between the pump and the 3 port valve there is a T joint reduced to 15mm which goes to the gate valve in question then goes to the return pipe.
This valve appears to be only half open, I have left it as it was before. just like to know what it is and what it does?. thanks
