I live in central Fl and my water is very hard. my daughter lives in SC and she bought a home in 2006 .It had a rainsoft water system in stalled in the home . There was only one person living in the home before my daughter bought the house. my daughter had the system disconnected when she had a new water heater installed the same year she moved in. With that said, I was wondering if I would be able to use the system in my home. she told me to take it . Is it worth my while to have it hooked up? Its been sitting in her garage since 2006, not hooked up.I figure it only had about 5 or 6 years of use. Is there any downside to using this older system? The only part that is a dated is the clock on the top of the tank, its a mechanical, not digital timer. do they have to do anything to the tanks? The thing looks almost new. What do you think they would charge to reinstall the system? thank you very much for taking the time to read this post.
