In accordance with recent federal regulations, you may request that Chesapeake Utilities install an excess flow valve (EFV) on your existing gas service line. An EFV is a mechanical safety device installed inside a gas service line between the gas main and the gas meter. Although an EFV is not required for the normal, safe operation of your gas service line, an EFV could help mitigate the consequences of a service line break by restricting or stopping the gas flow.
EFV Conditions and Information
Customer Eligibility: Many customers already have an EFV installed on their existing service line; those who do not may be eligible to have one installed. Most residential and small commercial customers will be eligible. If you are interested and to determine if you are eligible to have an EFV installed, please contact Chesapeake Utilities at 800.427.2883.
Safety Benefits: An EFV is designed to shut off the flow of natural gas if a service line is inadvertently dug into by a home owner or contractor during excavation. Restricting the gas flow after a gas service line is damaged may decrease the potential for property damage and/or injury.
What an EFV cannot do: Installation of an EFV will not protect against leaks on customer appliances or house piping. EFVs also do not protect against leaks on the gas meter or slow leaks on the service line.
Cost and Installation: The cost of installing the EFV is currently under review. Please check back for any updates.
