Turn the valve so that the flat part goes across the direction of the water flow through the pipe.

from the valve past, fowing in the direction of the liquid or gas. example: water supply coming from the street to your house, enters your house where your main water shut off is. then the water is distributed through your house to different fixtures. downstream of your main shut off would be everything past that valve in the direction the water is flowing, or all water lines IN your house.

Outside at the main shut off valve. Showers/Bathtubs do not normally have a shutoff valve like sinks and toilets. The main water valve for the house must be turned off.

Shut the water off at the main shut off where it comes into the house or at the meter and change the valve at the fixture. The valve at the fixture may be sweated on, compression, or threaded.

Tubs usually do not have shut off valve for them. You have to shut off the main supply. Depending on how the house is plumbed, you may be able to shut the cold supply to the water heater and that will shut off both the hot and cold or the main line where it comes into the house.

After a main water valve is closed the system's PVC pipes are still full of water and will drain to the lowest sprinkler head until the system is empty.

The water meter is shut off? The main water line is shut off? The valve for that faucet is turned off? The waterline is made of galvanized piping and has corroded shut? Aerator is clogged, remove and clean or replace.

If the shut off valve turns but does not shut the water off, the washer in it has split and probably made it to the faucet. It was blocking part of the hole on the hot side and at some point either shifted or made it through the faucet and in in the screen in the end of the spout. Shut the main water off and replace the washer in the shut off valve.

In most countries, the law clearly states that any fixture which draws water and comes from a live main feed shall always have a water shut off valve.

I'm not being stupid, you just change it. How ever it is installed, threaded on, sweated or compression fitting, remove and replace. I'm assuming water. There is another shut off valve further down the line. If it is the main shut off in the house, there is one at the meter. Shut the water off, drain the pipes and change it.

Shut off valve at the wall? Turn the main water line off and change it. How you change it would depend on what type it is and how it attaches to the pipe.

In every home thee are a number of shut-off valves. Where the water pipe enters the house is the main shut off, usually beside the PRV, a bell shaped device for regulating the house pressure. This main cold line will then branch off to the water heater, bathrooms and kitchen. Each faucet and the water heater and the toilet will have a shut-off valve. The hot water line comes out of the top of the heater and goes to bathrooms and kitchen. Each hot faucet also has a shut-off valve under it.

It is a valve on the floor, next to the toilet. The pipe from this valve feeds the toilet

On any water heater, the shut off is on the incoming cold pipe.

A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling

Check with your manufacturer. My (ancient) mobile home has a small metal placard affixed on the outside that says "water intake", which is where it is located (under the home). Newer models have a valve inside the home, but the location varies. Check near the shut off valve for the hot water heater.

Some shower valves have integral stops which can be accessed by removing the trim plate. Most shower valves don't have these and the water is shut off by turning off the main valve to the house or apartment.
