DI-TDS question

rmlevasseur · 08-11-2008, 07:12 PM

At what TDS do people generally replace their resin? My TDS readings went from 0 to 80 over the course of a month, which is still a hell of a lot better than my 580 TDS well water reading. MY membrane is still fine, I just think the DI is starting to leech back.

check the RO water before it is deionized.

At 80ppm you are past the point of needing to change out the faulty filters, you need to stop making water for your tank until this is solved.

Thanks PEM, but that doesn't answer my question. What is considered acceptable TDS? I know it is my DI, testing right after the membrane is 15 TDS
