Sounds like they hired the water guy before he finished his water plant operator schooling. Bad choice on someones part. For my money I choose well water from a good deep source. None of these shallow wells that are full of chemicals. I have never lived anywhere that I couldn't drink the tap water and have the confidence that it was far better than bottled water (since we don't know for sure where that water comes from) and safer to drink. I feel sorry for anyone that has to worry about their drinking water.

Having said all that, I think RO under sink systems are simply false security. Most people have them installed and forget about them. That's more dangerous than not having one at all.

Have you ever changed out a charcoal filter that someone has had in service for 3 or more years? It's disgusting.
