The Culligan repair person did an excellent job of resolving the problem we were having with our Culligan water softener. He addressed the issue quickly and went directly to fix it. Our water at the time was very hard and noticeably uncomfortable on my skin. I tested it with a kit, and it was hard at 7%. Only 2 days later I retested the water again and it was soft at 1.5% and felt great on my skin.
