Not a bad filter, for correct operation at low pressure in the system, a pump is needed to increase the pressure (otherwise the tank will fill no more than 3 liters). With a native water flow limiter, the flow rate was 1 to 6. I set the limiter to 300cc, the flow rate became 1 to 1.5. I measured the flow rate 1 to 2 with a 350mm limiter. When measuring water quality, the indicators are 20-25ppm (at the inlet 370ppm)
