The Coriolis Effect is definitely real. It drives ocean currents and weather patterns. But does it make toilets flush and tubs drain the opposite direction when you cross the equator? No.

Let me lay some science on you. And if that doesn't convince you, I'm the Toilet Guru and I have experienced toilet flushes in both the Northern and Southern Hemispheres. I can report that flush direction is a random mix everywhere. Keep reading for the details and pictures.

Toilets flush in a direction determined by how the water is poured into the bowl. For other vessels the pre-existing motion of the water, the shape of the vessel, and the shape of the drain dominate the direction.
