I have one of Marc's water makers. It's been running 8 months now and I estimate I've made 600G of RO/DI water. I have not changed any of the cartridges since the unit was new.
I just bought a Hanna Primo TDS meter. After calibration, the RO/DI water is testing 9 ppm.
I was planning to change the (2) carbon and (1) sediment cartridges. It is my understanding that as they foul, however, you lose output but not water quality. With the unit only achieving 9 ppm, should I also change out the de-I cartridge? Thanks!
