What you will need
If you want to stop the water to a single appliance like a sink it should have some type of shut-off valve that allows you to stop the water supply at the fixture without shutting off the water to the entire house.
To shut off a faucet, toilet, or similar fixture, first look for a stop valve that’s connected to the water supply tubes, located directly under the fixture. This is normally a chrome-plated or plastic valve. Beneath a sink, one serves hot water and one serves cold.
Turn the handle clockwise to shut off a valve. If it is too difficult to turn by hand, try wearing a work glove or gripping the handle with a pair of slip-joint pliers.
If you want to switch off a water heater or washing machine you will need to do something a bit different.
To shut off a water heater, turn off the cold-water valve above the water heater.
To shut off the water supply to a washing machine, just turn off the valve behind the machine. Some washers have simple lever-style valves.
If you don’t find a shut off valve near a fixture or appliance, you can shut off the valve that controls the flow of water to the entire house, normally located near where the cold water pipe enters. In some cases, the valve is located on a pipe right before the water heater and may have a red handle. To turn it off, rotate the handle clockwise.
