Family was complaining about the hard water in their home, we had just been in the Mills River ( just south of Asheville) area just last week. So they brought their sample water to our North Asheville office for a free test and with the results decided to go for a water softener for the calcium buildup and a neutralizer for the pH balance for the water. After the installation and testing the water in the system they were very happy and very impressed with our service. And they were especially happy that if we sell American made products.
