This new Weaverville customer called Mountain Water Systems with concerns of hard mineral build-up (Hard Water). They had an existing iron filter, but was still having a small amount of staining. They were also concerned with the hard minerals damaging their instant water heater and other appliances. We tested the water, which showed the water was moderately hard. We recommended adding a water softener to remove the hard minerals from the water. No further build-up in this home!! No more Hard Water!
