Culligan system installed. Warranty covers just the tank 1 year on everything else. Guess what everything else is what breaks not the tank. These guys sold me a $7,000 system that was small and poorly made. It was just a tiny little softener. They said it would take out all of the limestone but only removed about half. They charge for every visit and at this point I stopped making my payments. Culligan of Maryland, Stoner Enteprises, cheaply made crap.
