What Utilities Should You Shut off During a Flood?

Last updated October 26, 2026

The short answer

Turn off Electricity First

Electricity is the most urgent utility to shut off during a flood. Water conducts electricity, and live wires can create shock hazards in standing water. If the main breaker is in a dry area and you can reach it without wading, turn it off. If water has already reached the panel or you are unsure, do not go near it.

For a flooded basement, the breaker panel is often in the basement. If that area is wet, wait for the pros to handle it. They have the training to safely disconnect power. You can also call your electric utility to shut off service from the outside. Always prioritize your safety over protecting appliances.

Shut off the Gas Supply

Gas leaks are a serious risk during floods. Floodwater can damage gas lines or shift the ground, causing leaks. If you smell gas or hear a hissing sound, leave the home immediately and call the gas company from outside. Do not flip any switches or use a phone inside, as sparks can ignite gas.

If you know the gas shutoff valve location and it is safe to reach, turn it off. The valve is usually next to the gas meter. Use a wrench to turn it a quarter turn until it is perpendicular to the pipe. Once you shut it off, only a qualified professional should turn it back on after an inspection.

  • Gas shutoff valve is usually at the meter
  • Turn valve perpendicular to the pipe
  • Only a pro should restart gas service
  • If you smell gas, evacuate and call the utility
  • Never use electrical switches if you suspect a leak

Stop the Water Flow

Shutting off the main water valve stops more water from entering your home. This is especially important if the flooding is from a burst pipe or a leak, not just outside rain. The main shutoff is often near the water meter, in a basement, or outside near the street. Locate it now so you can act quickly later.

If the water is rising and you cannot reach the valve safely, do not risk it. Focus on getting to higher ground. Once the flood recedes, the pros can help with cleanup and repairs. Knowing the valve location in advance can save you time during an emergency.

Know When to Leave

Your safety matters more than any utility. If floodwater is rising, evacuation orders are issued, or you feel unsafe, leave the home. Do not wait to shut off utilities if doing so puts you in danger. Move to higher ground and take essential items like important documents and a phone charger.

After you are safe, you can contact your utility providers to shut off services remotely. They can disconnect power or gas from outside. In some cases, the pros may need to assess the situation before you return. Follow local guidance from emergency services.

  • Leave if water is rising quickly
  • Follow evacuation orders immediately
  • Do not wade in moving water
  • Take essential items with you
  • Contact utilities after you are safe

After the Flood Recedes

Do not turn utilities back on yourself. Have a qualified electrician inspect the electrical system and a gas professional check the gas lines. Water can cause hidden damage, and turning things on prematurely can be dangerous. The pros can assess and handle the restoration safely.

Document the damage for your insurance claim if you have one. Take photos of the affected areas and list damaged items. Policies vary, and your insurer decides what is covered. Keep records of any temporary repairs you make. For cleanup, consider hiring local water damage pros to handle the drying and sanitizing.

Frequently asked questions

Can I turn off the electricity if the breaker box is in the flooded basement?

No, do not enter a flooded basement to reach the breaker. Water conducts electricity, and that contact can be fatal. Call your electric utility to shut off power from outside, and wait for the pros to handle the situation.

What should I do if I smell gas during a flood?

Leave the home immediately and go to a safe distance. Do not use lights, switches, or a phone, as sparks could ignite the gas. Call the gas utility from a neighbor's home or your cell phone once you are outside.

How do I find my main water shutoff valve?

Look near the water meter, which is often in a basement, crawl space, or outside near the street. It may be a wheel or a lever. Trace the pipe from the street into your home. If you live in Cincinnati, write down the location now to save time later.
