Hi all. I have a double feed indirect system with a three-port diverter valve.CH is working but no HW. I suspect is the valve that has packed up!
My question is:
1) do i have to replace the whole valve or just the motorized head will do??
2)if just the motorized head will do, do i have to empty the system till below the valve or no need for that?
Thank u.
