Brand new 100GPD 4 Stage RODI unit I setup yesterday, and just my luck, I placed the Carbon and DI cartridges in the others respective place. I ran the system for about three hours this way, all while checking with my HANNA TDS Probe- first reading was 16TDS. It was late in the evening so I didn’t see some of the carbon sediment at the bottom of my bucket DUH!! Well, I swapped out the cartridges, and ran the unit for the past 5 hours. Randomly testing the water and I still have 16 TDS. DI cartridge is half yellow/blue. Did I destroy the DI only; is the membrane suspect now as well?
Should I just replace both DI + Membrane?
