A toilet flushed S of the equator swirl’s in the opposite direct to a toilet N of the equator.?

Is this in any way related to the direction of orbits and the rotation of the galixy?
Update: I don't understand this except I know it's because of the earth’s rotation. What I’m asking is does the rotation of our galaxy have anything to do with the direct of orbits and the direction of planets spin in our solar system. Is it a similar type thing?
Update 2: I know sailors that observed the swirl in the toilets change directions after they crossed the equator on the ship.
