Be sure to change out the sediment and carbon filters every 6 months (no matter how much you use it). Change out the DI resin as soon as you get 1 ppm tds. You should be able to achieve 0 ppm tds this way, and if you swap the two ROs like I suggested you actually won't burn through many more RO cartridges than if you were only running one.  |
You mean run them in series? Do I would have the clean water from one membrane go into the other? 2 RO waste drains? Or parralel them?
