My rodi started showing 2 tds coming out so I have more filters on order. Today I checked and it has 0 tds coming in to the di and 2 tds coming out. Is that possible or is my tds meter acting up?
 
any idea what pressure the water coming in is? My filters have a min and max pressure listed that they will work and notice that when I attach it to my sink and run full blast, I get 5-10 TDS but if I have it on half, I get 0 TDS
 
My tap is about twice that... I use my drinking RO for tank water too and my RO side TDS has been holding for the past year.
 
Check the orientation of the probes.
one of them could have twisted out of alignment. Looking through the T fitting, the pins of the probe need to be on the left and right so the water passes through the two pins.
If they are lined up dead center it will not work correctly.

When was the last time you checked your resin.
600G going through a single canister of mixed bed, I gather the Anion is shot.
