Anyone have any ideas what could be going on with my RODI system?
I have a 7 stage with separate cation/anion/mixed DI. All of a sudden I have 10 TDS going into the cation, and 11 tds coming out of the anion.
Anion was fairly newly refilled, so I took the canister off and tapped it on the table a few times to see if there was any channeling going on. Didn't help. Did the same with the cation. didn't help. Replaced the anion resin. Didn't help.
Took the housings off to see if they had mold growing or something, they look clean.
It's been set up for years and working fine, so it's not an installation issue.
Does DI resin go bad in a sealed bag? This anion resin was 2 years old, but still sealed.
I also swapped the TDS probes out and got the same reading.
Also, the TDS is 0 after the mixed bed, so it's not something coming through my water that DI can't remove..
