Faucets and Sinks
Even without hot water, you may notice that your faucets still run fairly normally during a power outage. Homes that are connected to the local water supply should still have access to cold water. People who use an electric pump to draw water out of a well may temporarily lose access to water.
Keep freezers and refrigerators closed. Use a generator, but ONLY outdoors and away from windows. Do not use a gas stove or oven to heat your home. Disconnect appliances and electronics to avoid damage from electrical surges.

During a power outage, many plumbing appliances in your home, such as toilets, sinks, and showers, can still be used thanks to gravity-based water systems. However, it's important to be mindful of the limited supply of water in your pipes and tanks.
Remember, while you may be able to use your cooktop, you won't be able to use your gas oven, since it needs an electric ignition to get going.

In most cases, water heaters require electricity to function. Without power, you might end up with a cold shower. If you're comfortable with cold water, this might not be an issue, but if not, it's best to wait until the power is restored.
