There's a theoretical reason why, in a perfect container with perfectly still water, the water would circle the drain in different directions in the northern vs the southern hemisphere. How ever this effect (called the Coriolis effect) is quite small and minor differences in drains and currents in the water probably have a greater influence on the direction of circling the drain.
This is the hydrostatic valve. If the pool is emptied it is removed to relieve water pressure caused by the surrounding water table If not removed a pool can float out of the ground.
