Both clockwise and counterclockwise flowing drains can be found regardless of the hemisphere in which they are observed. The Coriolis force is too weak to affect such small bodies of water, which is why this occurs. The effect is more measurably observed in large bodies of water like the ocean which is where hurricanes and typhoons begin to emerge. The reason the Coriolis effect takes place is because of the northern and southern pole. If observed from the northern pole, the Earth rotates counterclockwise however when viewed from the southern pole, the Earth appears to rotate clockwise. The analogy of a spinning disc helps to illustrate this image. From the top, a disc appears to spin clockwise as it plays the content stored upon it, but if viewed from below, that same disc would appear to the observer as if rotating counter clockwise
