When delivered, the pre-inflation of the tank keeps the plated membrane in the upper part of the tank. To permit changing the water volume, change the inflation
pressure to a pressure that is close to the static head of the system (see below), fill the system with water (purging the air) to a pressure value that is 10 to 20 kPa
higher than the pressure in the tank.
