The very versatile Super Cart is 3 stage system with a whopping 40" DI unit after the RO. This means you'll change out the DI resin less frequently than most 3 stage systems. There is also the ability to run it in 'DI Only' mode for situations where your input water pressure is low, allowing you to clean 4, 5 or even 6 stories without the need of a pump.
