It doesn't always turn clockwise (assuming you're in the Southern Hemisphere), that's just an old myth based on the effect of Coriolis force on large scale things such as air masses, but it plays no part on water in a sink or toilet, which are many, many times smaller than a cyclone.
clockwise
To turn on the water in the kitchen sink, locate the faucet handle and turn it clockwise until the water starts flowing.
To turn off the water under the sink in the bathroom, locate the shut-off valve usually located on the water pipes beneath the sink. Turn the valve clockwise to close it and stop the water flow.
To turn off the water under the bathroom sink, locate the shut-off valves usually located on the pipes beneath the sink. Turn the valves clockwise to close them and stop the water flow.
To turn water on in a sink or faucet, you typically twist the handle or lever located on the faucet in a clockwise direction. This action opens a valve inside the faucet, allowing water to flow out of the spout.
To turn off the water under the sink, locate the shut-off valve usually located on the water supply line leading to the faucet. Turn the valve clockwise to close it and stop the water flow.
This is the Coriolis Effect, though it does not apply to processes as small as water draining in a sink, for example.
The purpose of a bathroom sink shut off valve is to control the flow of water to the sink. To properly operate it, turn the valve clockwise to shut off the water supply and counterclockwise to turn it back on.
To efficiently turn off the water under the sink, locate the shut-off valves usually located on the pipes connected to the faucet. Turn the valves clockwise to close them and stop the water flow.
Yes, I almost always drink sink water and never get sick, although it may vary from place to place.
The direction in which water drains from a sink is mainly determined by the sink's shape and any residual motion. The Coriolis effect, influenced by the Earth's rotation, is too weak to influence the direction of water draining in sinks. Therefore, it is a myth that water drains in different directions in the northern and southern hemispheres.
To use a sink wrench for tightening or loosening fittings in a kitchen sink, first, ensure the water supply is turned off. Then, place the wrench on the fitting and turn it clockwise to tighten or counterclockwise to loosen. Use steady pressure and be careful not to overtighten.
