We had a bacteria problem with our well water, making it not safe for drinking water. We did have a old RO drinking system that wasn’t producing very much or even very good water. We had Infinite Water come out and test our water. We purchased a new drinking system trhough them. Our water is now safe to drink and tastes excellent! It’s of equal if not better quality than buying jugs of water. Makes great coffee and tea! I think we drink more water now than we ever have.
