TDS meter reading 0 at stage 6 and 1 at stage 7

[SeeFu]

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.

WHat order are the DI resins in?

cation first, thenanion

1 tds could just be an error for the tester

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?

i plugged in a 2nd meter, still reads 1

 

[SeeFu]

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.

I'm having a similar problem where my TDS is 2 going into the DI and 1-2 coming out, almost like it's not doing anything at all. I've repacked it, switched my meter probes and still no luck.
