Several years ago I installed an RO water system. I think RO water is controversial as it removes everything from the water, good stuff (ie flouride) and bad. I have also heard that it is hard on appliances i.e. coffeemakers as the water is "reactive" in the sense that it leaches ions from metals and wreaks havoc on them over time. SO, I am wondering if I should abandon it when I renovate. Although we condition the water for the household, I have "hard" water as the cold water supplied to the kitchen. What are the best options for water filtration? Please advise I am on Indianapolis Water.
