Thanks, Frank.
So, there has been more work but little progress on this system and for quite an embarressing reason.
I plumbed the system Friday. I filled it with water and instead of the proud moment watching the powerful pumps in action, I got the down feeling of a dud. Something was wrong. After troubleshooting, I realized I had reversed the intake and outputs for the closed loop.
With the feeling of defeat in my blood, I proceeded to drain and replumb the system. Again I filled the system and flipped the switch. The feelings of pride quickly dissipated as I realized I had just finished replumbing the system the exact same way. Dejected in defeat I decided to call it a night and go to bed. I'll probably hit up HD this week and give it another go.
