I just bought a refrigerator from home depot and they said they wanted to send someone out to check my water for free. I agreed, thinking it was a service they were just providing. It turned out to be more of a sales pitch for this water softener. At first I was mad, but then some of the tests he was doing kind of impressed me. Then, I found out how much it costs (a little over $4,000) and am wondering if it would actually be worth it. So, does anyone have the system? Like it? Hate it? Worth it?
