I love the soft water. The resin tanks work well in the older house we live in. The water was very hard before we had Culligan and my hair was turning into straw. My husband needed the soft water because of psoriasis.
I love the clean tasting water and that I don't have to wait for water to heat up for my tea or cocoa. I also love the customer service, they have been so ready and willing to work with this forgetful mother of 4 on delivery days!
