Randen, if you have any photos of the towel rack, I'd love to see how it turned out.
Also, I seem to recall that we had a discussion about purging a ground loop.
Well, I came across
this document that you might find useful.
Sorry, but it does not address the minimum feet per second to do a good purge.
However,
this document gets right in to that information. (HINT: 2ft/sec)
additionally you might be interested in
browsing about on this page. Looks like interesting information here.
