Joel, you are absolutely right, the hot water will circulate all the way to the footbox constantly , I don't know what I was thinking, I guess I was not thinking at all. I guess I saw a build that did it that way and seemed like a logical way to connect everything at a good location, except for the heat issue , which being in West Texas is a big deal .
Again thanks for your help, now I have to brake a bunch of Oetiker clamps and start over, but better now than latter. Thanks again for the heads up.
