Excess Flow Valve (EFV) Notification

April 2017

Full Details: EFV Installation


An EFV is a mechanical safety device installed in a natural gas service line between the natural gas main and the natural gas meter.

EFVs minimize or stop the flow of natural gas in the event of a service line break.

EFVs will not work properly on all natural gas services; therefore, not all customers qualify for an EFV.

You may choose to have an EFV installed on your service line
Installation of an EFV is optional. Costs vary and are the responsibility of the customer. Residential costs are likely to exceed $500.  Commercial costs are likely to exceed $1000, but will vary depending on the complexity of the installation. A quote will be provided upon request.

Quick Facts:

  • Most residential customers with service lines installed after 2009 have an EFV included on their service line.
  • EFV's can not be installed on some service lines due to high gas flow, low pressure or other factors.
  • EFV's are not designed to close if a leak occurs beyond the gas meter on house-piping or appliances, or if the leak on the service line is small.
