Also, I agree with the nature of your assessment. It is the system that appears to be out of logic. I don't know this system, but is it possible that a pair of hoses got switched at some point and one or more loops are trying to operate with reverse flow?
Hoses didn't get switched. Nothing that drastic could have happened. I was watching the whole time. Hmmmmm....

I think I'll let the brain trust (POG) do its best while I head into Yellowstone, talk with God about this and other issues I'm having, and when I emerge from the park, the problem will be solved. :-)

Thank you all for your help!!
