How much water have you made? I have read that the pre and carbon filters should be changed at 6 months as bacteria can grow in them, but ro membrane can go a few years. I usually change my di resin when it moves from 0. Is you tds meter calibrated?
im not really sure... maybe around 1000 gallons... is that a lot? i believe it is calibrated...
