What Happens If a Gas Line Is Damaged During a Storm Event?

After a storm, strong winds, falling trees, or shifting ground can crack or break a gas line. The most obvious sign is a strong odor like rotten eggs, which gas companies add to make leaks noticeable. You might also hear a hissing or whistling sound near the line, or see dead vegetation or bubbling water in the area.

Other signs include a white cloud or mist near the line, or a dusty area where soil is blowing. If you notice any of these, do not investigate closely. Move everyone away from the area and keep pets with you. The priority is getting to a safe distance, not confirming the leak.

• Strong sulfur or rotten egg smell
• Hissing or whistling sound near the line
• Dead plants or bubbling water along the line
• A visible mist or cloud near the ground
• Dirt or debris blowing from one spot

You may need to shut off the main gas valve, but only if you can reach it without danger. The valve is usually near your gas meter, often on the outside of your home. Use a wrench to turn it a quarter turn, so the handle is perpendicular to the pipe. Do this only if the area is dry and clear of any flames.

If you are unsure how to shut it off, or if the valve is in a flooded or damaged area, leave it alone. Your gas utility or a qualified professional can handle it. Once the gas is off, do not turn it back on yourself. Only a professional should restore service and relight pilot lights.

• Find the valve near your gas meter
• Turn the handle a quarter turn to close
• Use a wrench only if the area is safe
• Do not turn gas back on by yourself
• Call your utility for help if needed

After a professional repairs the gas line, they will test the system for leaks before restoring service. This often involves pressurizing the line and checking with a gauge or a special detector. You may notice a faint gas smell during the test, but that should disappear quickly. Ask the pro to explain what they did.

If you had water damage from the storm, such as flooding or a broken pipe, you may need to dry out walls, floors, or belongings. Water damage pros can remove standing water, dry the structure, and help prevent mold. They can also check for hidden damage behind walls or under flooring.

• Ask the pro for a leak test result
• Keep the area ventilated after repair
• Watch for any lingering gas smell
• Dry out wet areas to prevent mold
• Check your insurance policy for coverage details
