Why don't you try a different source of water? Perhaps get some from a different RO unit or purchase some from a store? It might not read 0 TDS but it might help. Perhaps one of your RO system filters constatly introduces some organic waste into your water?

Thanks. I did use a lot of Co-op ro water for the changes, something I have done many times in the past.

I do wonder if its ro related though. Just before all this downfall happened, I changed all my filters, including my membrane. Thats when I had the restrictor problem with the smaller membrane. I was getting a higher tds from the membrane then but we now know why and it was still 0 from the DI resin.

Its reading 2ppm from the membrane now and 0ppm from the resin.
