What Clients Say
I have been a Culligan customer for 18 years. We had our house plumbed for a water softener then leased the actual waters oftener from Culligan. They take care of it, salt, any upkeep or replacement as necessary. The tech, Robert, is fantastic. Personable and professional. Highly recommend
