What Clients Say
Great service and product. We have purchased a RO system for our new home and love the convenience of on demand fresh filtered water. We have been customers of Culligan water in different homes across the country and have always been happy with them. We did have a defective o ring that caused a leak at installation but Culligan has made it right. Everything is back to its original condition. We will continue to recommend Culligan to our friends and family. Thank you for living up to your reputation!
