zoned hot water system problem

Yes. After I replaced the pump I fully opened (bypassed) the
flo-control valves and ran all of the circulator pumps to hopefully
flush any dirt from the seats and get the air moving. Then I closed
all of the flo-control valves. They were all closed when I got there
and hadn't been touched in years if ever.
Well, then if they are tight and have been there for awhile and you
are getting ghost heating you may want to try and replace one of the
check valves. There really isn't much to forced hot water system.
I was thinking about trying that but all three flo-control valves are
allowing flow no matter which of the zones is calling for heat. That
would mean all three of them have failed or are stuck, he also told me
that he has always gotten heat everywhere in the house since he moved
in 8 years ago. This has to be an incorrect zone job done for the
previous owner.
