What Clients Say
I have been a Culligan customer since the 1990’s. At first I was renting the system to see if it met the needs of my family, and living out in the country would it really work for us. After a couple of years I moved to the city limits and purchased the reverse osmosis/soft water system. We sold our home in 2006 to family friend and they continue to use the system. 2019 I was searching for a different water system and after seeing the demos of a few of them, I went with my gut instinct and purchase another Culligan reverse osmosis/ water softener.(happy I listen to my instincts) Almost 3 years later we are happy to say Culligan remains to be one if the best water system out there for us. Part of me wish the softener was not so bulky but then again we don’t have to keep adding salt every month. The service reps/delivery person (do not remember names) have been very respectful and very helpful) He always takes the time to put our 5 gallon water jugs where we ask him too. Thank you so much Culligan!
