er.. how to raise it ?

If using dunso then increase the size of hole for the air or raise the level of the dunso.

If not dunso then raise the height of all pipe in the overflow box or reduce the opening of the overflow pipe in the sump.

The key is to raise the water level in the overflow box so there is less drop in water level.
