Mr. M is on our annual maintenance plan for his water softener. Every year we come out to the home to take care of the annual maintenance. This plan keeps the warranty on his evovle water softener. Shae, our technician, was able to do the 10 point performance check on the softener, and deliver their salt for the year as well. He tested the water before and after the water treatment equipment to make sure they had perfect water quality. He also changed their reverse osmosis filters at this time too.
