We recently moved to Moscow and our home had an existing Culligan system. We started experiencing scale buildup on shower surfaces as well as a noticeable change in water quality to the poorer. I called our local Moscow Culligan and Sierra (I hope I’ve spelled it correctly) put Rob in touch with us. Rob was very patient and professional as he explained everything he was doing to our system. He answered my questions and helped me gain enough understanding to take care of most routine maintenance myself. Our water is amazingly better and we appreciate the courteous service!
