We moved into our home about a year ago and inherited a newer system with the home purchase. Keegan came out and explained the limitations of the Culligan system with having only one tank and the reasons we were seeing iron staining in our new showers and tubs. While they were not the cheapest we believe you get what you pay for and we have been very happy with the service, quality, and reliability from day one. If we have any questions Keegan is quick to answer and solve them. We highly recommend him and his product!
