How accurate is water just falling straight down the hole in determine the equator?
Water doesn't flow directly downwards at the equator, and outside of the equators, it can be influenced to rotate in either direction. The Coriolis effect over a short radius in minimal. Viscous effects will cause any original perturbation to influence the direction of flow.
Coriolis is an illusion to us flat earthers!
