Does water swirl clockwise at the equator when it drains in a sink or bathtub ?
since whirlwinds and water swirls opposite directions depending on which side of the equator you are at, which way does it swirl at the equator ?

you are referring to the Coriolis Effect, the effect of the Earth's rotation on the apparent motion of objects
the Coriolis Effect has no effect whatsoever on water swirling down tubs at the equator, north pole, or any where else
the motion of water in a tub or basin is hugely more sensitive to the initial angular momentum of the water when it fills the tub, to friction between the water and the tub surface
this is one of the classic myths about physics, but the reality is that while the Coriolis Effect does influence the motion of winds around large weather systems, it has no impact on water in tubs or sinks

It depends on who manufactured the toilet. The swirling motion you see if caused by the water jets, that fill the toilet back up with water. If you look at them closely, they're angled slightly and they case the water to swirl.
