    High TDS in RO/DI Water

    Yes, we've got a carbon prefilter, but you are right, our community water has alot of chlorine in it, (I can smell it). I've got new filters on the way and will install a second prefilter. Will make sure we keep extras on hand. Thank y'all so much for the help.

    High TDS in RO/DI Water

    Yes, after we installed it the readings were zero. I didn't really test it again until recently, when I got the 254ppm, we flushed the system and the TDS went down to 60, but was moving around quite a bit and never went lower than 60ppm. The pH in our tank is 8.2.

    High TDS in RO/DI Water

    We installed an RO/DI system about 3 months ago. Initially the TDS readings were zero, recently a test of the RO water read 254ppm. I've ordered new filters just to be safe but the system is new and our tank is 65 gallon so we're not using a ton of water. Any advice?
