An excess flow valve (EFV) may reduce the consequences of a gas leak in the event of a break in the outside service line. The valve is designed to shut down gas service to your home and reduce the likelihood of unrestricted gas flow from the broken line. Since February 1999, in response to government regulation, Roanoke Gas has been installing EFVs at no additional charge to customers on all new and replaced residential natural gas service lines, which we will continue to do.
Roanoke Gas will install an EFV on an existing residential and qualifying commercial natural gas service line for a cost to the customer of approximately $1,500 – $2,500, depending on the time and labor necessary for the installation.
For more information about EFVs, or if you want an EFV installed on your existing service line, please contact us at (540) 777-4427.
