The hardest part was waiting for the 48 hr soak so I could test the system. 50 plus hours later and some plumbing updates the system is in and running well. Within the next few weeks I will have the water tested. I must say that the water smells better and tastes better. We were getting an odd smell if you left water in a glass over night and the taste was very metallic. Both are gone. The other great thing is no more refrigerator filters. They became costly and very hard to find and I think the last batch we purchased might have been fake replacements.  So far this seems like a great investment.
