  • don wiesinger

    Use the salt drop off and it has worked well over the years as well as the tech always checks the system to make sure everything is working correctly. Great Service.

    I love Culligan. The equipment works great and most of all I love that I don’t have to mess with it at all. They take care of all the upkeep and refills and whatever I need which is perfect for me.
