I was in Ecuador & saw them with no swirl!

Ok I don't know about the Ecuador one - that sounds pretty interesting to see one with no swirl. But according to what I've read, the other factors (shape of bowl, angle of water entering bowl, etc.) far overwhelm the Coriolis effect, so you can get swirls both ways either North or South of the Equator.

You are correct, despite what I was told. Snopes is probably 95%+ reliable. It was counterintuitive anyway. I do wonder how they did the toilets in Ecuador, though. Probably just their way of plumbing. I even read about it in my textbook, I think! I know teacher(s) told me.
