Reverse osmosis systems

[Lynn]

Have a whole house filter system. Just put in a tankless water heater. Guess I am bit by the plumbing bug this week.

Since Zack's transplant he cannot drink tap water, either well or city water. We are on well water, but it isn't particularly hard. Don't remember the numbers, but the guy who tested it for us for the swimming pool was surprised how "unhard" it was for well water.

Still, we are lugging the 5 gallon bottles to use in a water dispenser for Zack to drink (and for our coffee pot - the well water is hell on coffee pots).

Thinking of installing a RO system under the kitchen sink with a uv treatment piggybacked on it. Only delivers like 2gpm, but it takes 1.5 min just to fill the coffee pot from the current dispenser, so no big deal there.

Just mind boggling how many brands are out there.

Would like to hear what others have used, and if you know, what to stay away from.

Thanks for any help.
