I have a pipe (the one in green) that I can't seem to figure out what it's purpose is. One part of it comes from the bottom of the hot water cylinder and the other is located after the pump but before the MagnaClean. It doesn't seem to serve either the hot water or the radiators. Can anyone point me in the right direction.
I've attatched my very best drawing
Thanks folks
