"I bought a Autotrol 255 Metered 40,000 Grain with the premium Resin on 1-27-09. I had trouble getting the meter to work but called and you told me that I had probably used too much flux when I soldered my pipes, which I have a tendency to do. I followed his instructions made the repair and the softener has been working great ever since. It uses a lot less salt than my old system and does a great job softening our water. I again want to thank you for all the help and I would & do recommend AffordableWater.us"
