Use a screwdriver to raise the water level. You need to attach the screwdriver at the rod’s interior end and continue adjusting it for your desired water level.
The water level should be just below the overflow tube of the tank. Continue adjusting the water level by rotating the screwdriver until you reach the desired water level.

To lower the water level, rotate the screwdriver clockwise, and to raise the water level, rotate it anticlockwise. Continue rotating the screwdriver only slightly until you reach the desired water level in the tank.
