    Not to hi-jack or anything, but what products do u use to test ur TDS? Have had my RO/DI system for about 9 months and just assumed I would replace filters every year...guess I might not need to do that after all!

    Hrmm, my RO/DI system is scheduled to arrive tomorrow, so I have no idea what the TDS in will be, or when to change my filters. I have read, however, that replacing the sediment filter at least every 6 months can greatly increase the life of the RO membrane. The unit I ordered comes with a TDS meter and a pressure gauge. I guess the theory is that the pressure gauge will show when something isn't flowing as freely as it should, thus indicating a filter in need of replacement. :freak3:

    OK, now I have the RO/DI installed! ;D

    158 ppm out of the tap
    156 ppm out of the Pur water filter (on kitchen sink)
    0 ppm from RO/DI ;D

    Now I just need to comfort myself and test for ammonia, nitrate, phosphate, silicates and anything else I can think of.

    Good idea testing that Pur water filter... sure didn't seem to be doing much!
