Keep your gas meter clear and dry
Keep the vent dry and clear of snow and ice at all times to avoid the potential for dangerous indoor natural gas buildup. In the photo below, the arrow points to the meter's gas pressure regulator vent.
The vent can become plugged when ice and snow melt during the day and refreeze at night.
We recommend keeping the entire meter assembly clear of snow and ice as well. Accumulated snow can prevent the meter from operating properly by stopping the flow of natural gas. Gently remove snow or ice from the natural gas meter and any associated piping. Carefully shovel around a meter and move snow away from it. Avoid using a snow blower near a meter. Always keep a clear path to your gas meter to allow quick access in an emergency. A snow-covered meter, in addition to being potentially dangerous, can also lead to a loss of service and freezing of inside pipes as a result of lost heat.
We strongly recommend that you check your gas meter regularly to ensure it is free of ice and snow, especially if the meter is exposed to melting precipitation. If you notice ice on your meter or are concerned that the meter's regulator vent may be blocked, please call your natural gas provider.
