NO.
Install low-flush toilets
Yes, but not in the way we think of flushing toilets. In private houses, a bucket or two of water was used to flush away the waste and prevent odor. In the public toilets latrines, there was a stream of running water beneath the seats to flush away waste.
Dual flush toilets usually use 3 and 6 liters of water depending on which way you push the flush handle - 3 liters for a little job and 6 liters for a major event. Single low-flush toilets use either 4.5 liters or 6 liters.
Not necessarily. The direction in which toilets flush is determined by the design of the toilet and the water flow, not by the hemisphere you are in. The Coriolis effect influences large-scale systems such as hurricanes and ocean currents, but it is too weak to affect the direction of toilet flushes.
Same way you smoke pot?
No matter what part of the world you live in water can swirl either direction. The assumption that it swirls different is just a myth.
The same way as in any other poker game. A flush consists of 5 cards of the same suit. If the 5 cards of the same suit are connected (56789 of spades for instance) you've got a straight flush.
The toilet is too small a scale for water to certainly flush in one direction or the other because of the hemisphere they can, in fact, flush both ways. However hurricanes will rotate clockwise in the northern hemisphere and anit-clockwise in the southern hemisphere.
"Canada" is written the same way in French.
Many people believe that toilets in Australia flush counter-clockwise (i.e. the opposite way of the United States' toilets). This is untrue, as the forces involved are too weak to influence flow on such a small scale; the direction of such floow in toilets and bathtubes is more-or-less random, influenced by perturbing factors in the system. Whirlpools do flow in the opposite direction on opposite sides of the Equator due to Coriolis Force, an effect of the Earth's rotation.
That is because toilets are now made to conserve water. The tanks hold much less and so they don't flush as well as they used to. Some newer ones now have a dual flush system to attempt to deal with this issue in a better way: one button provides a "light" flush for "light" loads - like urine only - while the second button provides more water for the heavier jobs.
They spell it the same way Americans do.
