It's a fact I've often seen quoted as well, and yes, the water here in England turns counter-clockwise at it runs away.

I once saw the water turning clockwise into the plughole in my tub and for a moment I figured I'd entered some sort of Twilight Zone...... Then I realized the hole was partially blocked, so that must have set up some kind of temporary vortex in the opposite direction.
