Thanks - I realize I was over simplifying the 'Tack them down'. I obtained quotes from several contractors - and those items you mentioned were the primary selection criteria for choosing the contractor. I choose the contractor who had the best ability to handle those types of things. (Hopefully I picked the right one - but I did ask alot of questions).

The Hi-Deluxe is a rubber mat system - and it comes with all the straps etc. We will be using galvanized anchors and all of the pipes will be anchored as well.

The term 'vacumm breaker' temporarily through me -- The HiDeluxe calls it a 3-way valve to perform that function - (http://www.solartrope.com/new/hidel.htm # 3) -- I understand it now that I reread your comment - thanks.

I've read the HiDeluxe install manual and reviewed that website -- they are pretty consistent in the concepts.

Any additional feedback experience appreciated.
