Silly RO/DI question

[DanG]

Regardless of manufacturer, your RO/DI kit should be taking whatever water you put into it and putting out between 0 and 2 ppm of dissolved solids.
I have an aquasafe unit and it's been fantastic for me. Production isn't quite what they say, but that's because my incoming water is cold, and all RO/DI units drop in production when the water is cold. I got the maximus kit, which was about the same as the cost as the one at J&L, but I got a pressure guage, the holding tank, a TDS meter and 7 complete sets of filters and 2 huge bags of DI resin.
