Before they would even quote, they took water samples and have them analyzed by Midwest Laboratories at no charge to me. I found them to be the only company of 3 in Omaha that did this. We chose their product, a reverse osmosis drinking water system, several months ago and have been very happy with it. Yes, it was a little more expensive than the competition . . . but the competition tried to convince us we needed a $3000 water softener. Based on the objective data offered by the water analysis, it was clear that we did not. My recommendation goes to Ecowater.
