This system is about 1.5 years old. We have very soft water at my house, so I think it has quite a bit of capacity left. The TDS readings are about 1-2 ppm after the first stage and, of course, 0 ppm after the last stage.
The unit comes with a 2 switchable TDS sensors to measure TDS at 4 points in the system. It also has a swappable orifice to adjust the rejection rate depending on the TDS levels in the source water. Also features a manual flush.
The unit is in excellent cosmetic condition, just a tiny amount of oxidation on the gauge and part of the powder coated frame.
$200 shipped and PayPaled.
It's this unit.
