Aquatic Life Twist in 100gpd RODI. It's a few years old. Has always read 0 TDS until recently it's reading 2-3. Water pressure is good. I changed all filters and RO membrane, swapped leads on my TDS meter, and no change. Another thing is that its not depleting the DI resin any more. The big difference of when it started was that I moved my tank upstairs, and kept the RODI downstairs. But it didn't seem to start until about 10 months in. Basically my filter is mounted on the wall downstairs, the waste water drains below the filter, and the RO water is pumped either A) upstairs to my ATO reservoir daily, (there is a check valve to keep it from draining back into the RODI) or B) to my mixing bucket downstairs next to the filter. Is there a problem with having the filter below the water outlet? Any ideas why my DI resin seems to be getting bypassed? @AquaticLifeProducts
