Russ my TDS just shot up to 7. Just recently it was at 0. I also just replaced my DI resin and it is exhausting quickly. Within a year I have replaced all of the filters. Any ideas?

Can you tell me your tds at:
Tap water:?
RO water:?
DI water: 7 ppm.

Also - what is your pressure?

What is your waste water to purified water ratio?

I am going to flush it and if I need to I will pull the RO tube and test there.

Tap 263
RO 71 ???
DI 7-8 after pulling the wastewater tube and removing the restrictor and flushing for 30 seconds then replacing.

Assuming those numbers are accurate, looks like the root of the problem is your RO membrane. Did you let the system run for a few minutes before taking the tds measurements? I want to mae sure that you didn't measure tds creep water.

Also - What is your waste water to purified water ratio? Line up 8 identical cups in front of your system. With your waste water tube in one hand and your di tube in the other, in the time it takes you to fill 1 cup with di water, how many cups can you fill with waste water?

What is your water pressure?
