What is black water drainage?

If you are going to install the device yourself, make sure you have enough knowledge to do this. The most important thing during installation is to drain the black water from the second filter, which should never enter the membrane, as this water, which contains carbon particles, should be removed. To drain the black water, you must open the filter chamber number 3 (white on the bottom left), then open the inlet valve of the device and turn on the device. Place a transparent container such as a pitcher under the opened chamber cap until about 6 liters of black water are removed. After the water becomes clear, close the inlet and turn off the device, then close the chamber in its place and restart the device and enjoy drinking purified water. Do not forget to install the membrane filter correctly in the special membrane housing located above the device. To achieve the desired quality, the tank usually needs to be drained twice. To do this, wait twice for 1 hour each time until the tank is full, then open the tap on the sink and allow the tank to drain completely. “The sign that the tank is empty is that the water on the sink comes out of the faucet on the sink without pressure and very thinly, about the size of a drop.” The third time the tank is filled, the water that comes out is ready to drink.
