Natural gas is a safe, clean, efficient fuel for home or business use. The following recommendations will assist you in using natural gas appliances safely and economically. Your local natural gas or propane provider may recommend additional safety precautions.
Because natural gas is colorless and odorless, a harmless but strong-smelling ingredient called "mercaptan" has been added to draw attention to any leak that might occur. If you smell this strong odor in your home or business, or you have other reason to suspect a natural gas leak, take action right away:
Since many people spend more time indoors during winter, we urge customers to use caution. For a safe and warm winter, please:
If your meter is encased in ice and you experience problems with your gas service, or if you smell gas - please call our gas emergency number (302) 454-0317 immediately.
State law requires you to call a utility locating service, Miss Utility at 811, before you start digging - these services are free. Save yourself time, trouble, injury and perhaps even a fine - call before you dig.
A qualified contractor should inspect your natural gas appliances and piping each year. Vent inspection is also necessary to ensure that any carbon monoxide is vented outside your home or business. These inspections can identify potential problems and ensure the safety of your family and employees.
Gas connectors need to be inspected regularly, and replaced as needed. Certain kinds of flexible connectors manufactured between 1970 and 1980 have shown a history of failing over time and need to be replaced prior to failure.
Only a qualified professional should check your connector and replace it if needed. Don’t try to do this yourself, because a brittle connector could fail with minimal movement. Replacements should be completed only after the gas supply is turned off by a qualified professional, who will also be able to ensure that all gas appliances are operable once the gas supply is turned back on.
After disconnecting any gas appliances, the gas connector to the disconnected appliance should always be removed and the fuel line should be plugged or capped. It’s a good idea to replace approved flexible connectors once every ten years.
An excess flow valve (EFV) is a device
that can reduce the risk of a natural gas leak in the event of damage to the
outside service line. EFVs are able to automatically reduce unplanned,
excessive gas flows in the event of a broken gas line, often the result of
However, EFV’s can only shut off the
excessive gas flow if the damage occurs between the gas main and the customer’s
regulator/meter installation. An EFV cannot address gas leaks or issues
with internal customer gas piping and/or appliances.
As a result of regulations enacted by
the Pipeline and Hazardous Materials Safety Administration (PHMSA) of the U.S.
Department of Transportation, Delmarva Power has been installing EFV’s on the
gas service lines of certain single family residences – either when a new
service line is installed or when an existing service line is replaced. With certain exceptions, customers whose
natural gas load does not exceed a certain size have the right to request an
EFV installation on their existing natural gas service line.
Delmarva Power will install an EFV on eligible existing
natural gas service lines, upon request. However, the cost responsibility for
the installation is still being decided by the Delaware Public Service
Commission. Please revisit this web site
for further updates.

have an EFV installed, contact our Gas Delivery New Business team at
