To get you oriented, here's an animation of what I find in MY bathroom in Connecticut:
If the animation doesn't work, here's a good still to demonstrate:
Note the direction the water goes, to the LEFT. We call that "Counter-clockwise".
If things are truly as we've been told, it should spin to the RIGHT in
But the silly physics people think the water flows in the direction the pipe feeds out of the toilet.
Once we get Down Under, I'll take another video in their W.C.
and see what transpires, and place the results on this page.
Then life can go on as normal!
So out of desperation I filled the sink in Melbourne (southern most city of our trip) and pulled the plug. Unfortunately the sink drains really well so I wasn't able to get too much cyclonic motion, but after 4 attempts (there goes my water savings bonus) I think the water drained counter-clockwise, just like in the 'states.
I'll see if I can stop the flow some and get a better result. More to come.
