I am very positively impressed by my experience with Culligan Water of Kingman, AZ. Don (of Culligan) came out to our newly purchased home as requested. He quickly analyzed our Reverse Osmosis purifier problems, replaced the membrane and the filters and had it functioning at 100% efficiency in a matter of 30 minutes!! While on premise, he checked our water softener for effectiveness as we wanted him to do. We learned that the softener, a "Water Boss" make, wasn't even capable, on a good day, of handling the softener demands of well water at 42-44 grains of hardness! Yes, the prior owner had under purchased a "Water Boss" which couldn't handle the needs. Don of Culligan gave us an estimate and we gave him the go-ahead to replace our system with a Culligan Gold softener. Don came back two days later, installed us, trained us and was finished in 1 hour!! Great work, cleaned up afterwards, left great peace of mind and a solid warranty! We recommend Culligan of Kingman and Don!
