I contacted Shawn after reading his comments on his website...he sounded like he wanted to make water softener systems easy to understand and maintain. His price was reasonable and the install was fairly quick. I had done research into the types of systems available and his, with the Clack Valve, sounded best. Shawn is very personable and as we have only had the system a few days I can’t offer much in the way of follow-up responsiveness. He answers my emails and phone calls (asking questions) in a timely manner.
