Ok I just got my little handy dandy TDS meter, and got some tap water out of the kitchen sink and it read 328ppm of TDS. I then went out and got one if the gallon jugs that contains my RO/DI water, tested it and its reading 0.004ppm I'm assuming that this is pretty good indication that my RO/DI water filter is working pretty good.
My question is this. Now that I'm armed with this information, at what ppm with TDS should I change out my filters, carbon and resin? I'm currently running a RD-102 6 stage RO+DI unit from WaterGeneral Mfg.
