..water @ the equator

...Ok, the equator and water going down plug holes...does the water really go down the plug holes different ways down depending where you live, north or south of the equator, or even on it. Uganda is on the equator and at the equator they do a demonstration to show in the north it goes clockwise and in the south anti and on the equator straight down....and it really does!! so for you science people, is it true??(I never was very good at science!!)
