Gas Line Safety
Meter ProtectionTo ensure the safe and efficient operation of natural gas equipment, please protect meters and vents:
- Keep snow from burying exhaust and intake vents and from piling up on natural gas meters. A snow-free meter can function properly. Unobstructed vents can also help keep the pilot lights on, allow your appliances to breathe and operate efficiently and direct combustion byproducts to the outside.
- Consider using a shelter specifically designed to protect the meter if you live in an area where snow and ice tend to build up on the meter. Do not shelter the meter with a metal sheet or wheelbarrow. When these or other metal objects, including trash cans, bicycles and/or gardening tools, come in contact with the meter, they can interfere with the system that protects the meter and associated piping from corrosion.
- Please ensure any outside gas meters are not in direct contact with soil or mulch below them. Natural gas meters have aluminum housings that can corrode and cause damage (creating the potential for leaks). Also, take care not to bury the valve at the side of the meter. This valve must be exposed for emergency responders.
Excess Flow Valve (EFV)
An EFV is a self actuating safety device that prevents unplanned, excessive gas flow from the gas service line into a home or building, typically caused by excavation damage.
An EFV isn't required for normal, safe operation of the service line. However, any customer can request one for service lines that are not newly installed or replaced. Dominion Energy has been routinely installing these devices as part of the ongoing Pipeline Infrastructure Replacement Program in Ohio and the Pipeline Replacement and Expansion Program in West Virginia.
This is what a typical EFV looks like. The actual installed EFV may differ from this photo.
- May prevent buildup of natural gas pressure and lessen the possibility of a natural gas emergency and/or resulting property damage.
- Provides safe working conditions for Dominion Energy personnel at the scene of mainline damage.
- Diminishes environmental impact by reducing the amount of natural gas escaping into the atmosphere.
If you have questions, or to request installation of an Excess Flow Valve, please Contact Us. During the call, we will determine whether the service line is eligible and, if appropriate, schedule an inspection and possible installation at a mutually agreeable date.

Cross Boring occurs when a utility unintentionally intersects or damages another utility's underground facilities.
