All 7 zones heat when any one zone calls for heat!

Summary 10/22
When any zone calls for heat, the (one) circulator pump operates properly, however all zones make heat. Only five of the seven four watts ¾ 200s-M5 flow check valves were replaced.

Update
10/22 11:07 Oops - My son just told me he only replaced only two check valves. MY BAD.
