We have well water and lived with it for 40 years using a variety of products to maintain and clean our sinks and other surfaces, and then.....we got a Culligan system! It has changed our life. no more Britta we drink delicious water directly from the tap my whites are not gray or rust stained from the washing machine, the toilet and tub don't need harsh chemical treatments to clean them. the Culligan system is well maintained by your workers and we are very happy.
