Love the under-sink kitchen reverse osmosis system, I've had it since 2010, Culligan even moved it to my new home. It was particularly useful during hurricane Ian when I had no water for almost a week, and annual filter changes are easy to schedule.
My reverse osmosis system works great already 4 years. Schedule annual Service call was easy, technician had arrived on time and did great job. Only cons are that the price goes up.
My kids and I love Culligan water. We rarely drink anything else and always leave home with several water bottles filled. Mast Family Culligan is super easy to work with, reliable, and flexible. I highly recommend Culligan!
Usually prompt and efficient. This last visit however, I noticed no softened water a few days after the visit and upon checking, found the controller was in a testing mode and not softening. I moved the controller back to operation and started a manual regeneration. Working fine now.
