The only name in water treatment that came to mind was Culligan... is there any other name that rings a bell? I personally think not, and I was not disappointed. The installation was very professionally done, and the equipment was clean, compact and easy to operate. Lets rate the overall contact with Culligan personnel from start to finish a solid '10'... good with service before and after the sale. A first class operation that we trust will continue. Our new water is AWESOME... and we thought our well water was good, we we're simply blown away with the treated water we now have, no real comparisons... just the best we have ever felt and tasted... even better than city water. Culligan takes the first prize in our opinion.
