My old RO system would put out TDS of 40 ppm. Nothing drastic but was present. Maybe an accumulation in the filters. Alkaline water where I'm at. I also have slightly elevated TDS from my hot water heater which I'm positive is from accumulation of hard water build up in the tank.
My water change is once weekly at 40-50%.
