From Bad Coriolis
"The Coriolis force is so small, that it plays no role in determining the direction of rotation of a draining sink anymore than it does the direction of a spinning CD. The direction of rotation of a draining sink is determined by the way it was filled, or by vortices introduced while washing. ... The direction of rotation of a draining toilet is determined by the way the water just under the rim is squirted into the bowl when it is flushed."
