You'll want to shut off your water at the main valve if you have a major water leak or a burst pipe to prevent major water damage and flooding. Your main water shutoff valve is typically located where the water enters your home, which is usually your foundation at the front of your home. You'll usually find the shutoff valve within the first 3 to 5 feet of the line. If you don't have a basement, look near your water heater, in a crawl space or under your kitchen sink.


Each toilet should have its own shutoff valve to cut the water. Look below your toilet to see a hose running from the toilet to the wall. Look for a little knob there, which is the shutoff valve. Turning this knob will shut off all water to the toilet. This can come in handy if the toilet is clogged and overflowing or if you need to remove the toilet and want to empty all the water.

Washing Machine

Washing machines have hoses that connect them to the water supply, which is typically on the wall behind the machine. You should see a red or blue knob for hot or cold water. Turn both knobs to shut off the water. You might need to shut off the water if the hoses are leaking or you're replacing the washing machine.


If you look under the kitchen sink, you'll typically see a line running to the dishwasher. It should have a knob or valve you can turn to shut off the water. Shutting off the water is often necessary if you have a leak or are replacing the dishwasher.

Water Heater

Water heaters typically have two shutoff valves: one on the cold water line running into the appliance and one on the hot water line running out. The cold water valve is typically blue, and the hot water valve is typically red. You might need to shut off the cold water if you're working on the water heater, have a leak or are replacing it. The hot water valve can be shut off if you have a leak in a hot water pipe.

Gas Line

As a general rule, you shouldn't handle any work on gas lines yourself. However, you might need to shut off the gas supply if you suspect a gas leak. Once you shut the gas off, call your gas provider to come turn it back on. The shutoff valve is usually before the gas meter, which can be outside your home or just inside where the gas line enters your home.
