I've got the brs 7 stage rodi system. After stage 6 u get a TDS reading of 0, but after stage 7 it goes up to 1. any idea what's going on? I've never had that issue before. All new resin in the system, the carbon reads 0 chlorine on one of those test strips.

If you are measuring TDS with a dual or triple TDS meter can you change the probes around and see if you are getting the same readings?

can't figure out why the DI resin on the last stage would add tds. its practically unused.

I'm not sure either. How much water have you ran through it? When I replaced my DI resin with a couple of new SpectraPure cartridges I had to run the water through them for a few minutes before they read zero.

i got tired of researching. just replaced the di resign. should have done that to begin with instead of starting by replacing anion. anion was only aout 1/2 used and di resin was basically 90% unused.
