I finally figured it was time to change out all the cartridges in my Aqua FX RO/DI unit. I didn't realize it was going to cost $120+ for everything I needed so I thougth I would try and salvage the parts from my old RO unit that was a POS that leaked constantly. It was only used to make a small amount of water so I figured the RO membrane, carbon and micron filter would still have some life left in them. I switched them over to my baraccuda and flushed it for probably 15minutes total. I filled and drained the holding tank several times but my TDS meter still says 7. I didn't have a DI cartridge replacement so I just left it off because it looked gross, could this be a problem?
BTW, my tap water is about 160 and when the unit was unit I got TDS readings of 0-2.
