Water is more affected by the surface geometry of the fixture than the hemisphere. Snopes gives a nicely detailed explanation at the link below of the urban legend that claims drains drain opposite on different sides of the equator.
The direction water goes down a drain is influenced by various factors such as the shape of the drainage system and turbulence in the water. The Coriolis effect, which influences large-scale weather patterns, is not strong enough to determine the direction water flows down a drain. Thus, it is not accurate to say water will consistently flow in a specific direction based on this effect.
Water flows in both directions regardless of hemisphere. In Physics, there is the Coriolis Effect that describes the flow/movement of water due to a variety of factors, and this is sometimes used to add validity to the myth, but the Coriolis Effect does not occur in small bodies of water such as a sink or toilet. The direction of water flow in a a sink or toilet depends on the direction that the water flows into the sink or toilet -- regardless of hemisphere. You can test this yourself by pouring a pitcher of water from the left side of a sink and then from the right side, you will see that the water will flow accordingly -- this experiment will have the same result in Sydney, Australia as it will in London, England.
It can flow either way.
In North America, water typically goes down the drain counterclockwise due to the Coriolis effect. However, the direction of water flow in a drain is more influenced by the shape of the basin and the way the water is introduced rather than the hemisphere it's in.
A trip lever drain in a bathtub works by using a lever mechanism to open and close the drain. When the lever is lifted, it opens the drain, allowing water to flow out of the tub. When the lever is pushed down, it closes the drain, preventing water from draining out. This mechanism is controlled by a linkage system connected to the drain stopper, which moves up and down to control the flow of water.
To effectively unclog a drain using boiling water, simply boil a pot of water and carefully pour it down the clogged drain. The hot water can help break down and dislodge the blockage, allowing it to flow through the pipes. Be cautious when handling boiling water to avoid burns.
Contrary to popular belief, water swirling down the drain is no related to the Earth's rotation or the Coriolis effect. The swirling vortex over the drain is likely related to angular momentum; the distance from the center of the rotation determines the speed of the rotation. o
To open the kitchen sink drain, locate the stopper or plug at the bottom of the sink and remove it by twisting or pulling it out. This will allow water to flow freely down the drain.
the cold water moves down.

A trip lever drain stopper in a bathtub works by using a lever mechanism to open and close the drain. When the lever is lifted, it pulls a plug out of the drain, allowing water to flow out. When the lever is pushed down, it seals the drain, preventing water from draining out of the tub.
Water flows in a sink due to gravity pulling it downward. When the faucet is turned on, water is released and flows down the drain due to the force of gravity.
