Again, amateur move on my part but looking at my valve controls, they stay the same as if I have a water hose hooked up from an outside source.
To repost the pic, the sticker on the top right says "City Water Hookup/Winterize" and shows both valves stay up/down instead of left/right.
I followed both lines on the reverse side and what I believe happens is, the pump automatically pumps the antifreeze because the "city water" hookup has a cap screwed on. Since that is closed/sealed off, it diverts to the other outlet for the antifreeze and pumps from there. I bet if I unscrewed the water hose inlet, it would not pump because it couldn't prime itself pulling from 2 areas at the same time.
Boy did I learn a lot tonight. Thank you to everyone!!
