Great service! Ben, my delivery guy, is awesome! He delivers water and fills the softener with salt every month. He always communicate when he will be there. It is one less thing in my life that I have to worry about so Thank You Rock Valley Culligan!

Just purchased a new water softener. Chris made the process very easy. He presented several financing options and explained them so we understood everything.
