I have a question about the safety of the plastic that is used to make the 2/3/5 gallon water bottles that you refill with reverse osmosis water. Is it safe? Our city water supply is so horrid that even the doctors here in tell you to NOT drink it cause it'll do a number on your health. So we buy RO water and keep it stored in the plastic bottles. Is that a bad thing? I refilled all 3 of mine yesterday and it finally dawned on me that it might not be a good thing to do. Does anybody know?
