Are there any reverse osmosis alternatives. I'm looking to buy a house that has a water softener and reverse osmosis water treatment. The water lines in the house are copper. I have been told, and found out online that R.O. wil deteriorate the copper lines. The toilet tank is showing a green tint. Will I have to replace the plumbing or is there a treatment for the water to stop further deterioration? This is holding me back from buying the house. I am going to get water tests from the well and the house to see if R.O. is needed and if the green tint is copper or not.
