Excess Flow Valve

GUC wants to let you know that an excess flow valve (EFV) is available for installation on your GUC natural gas service line. EFVs are mechanical shut-off devices that can be installed in the gas pipe running to the gas meter at your property (the “service line”).  An EFV is designed to stop the flow of gas if the service line is broken, for example, by an excavation accident. Stopping the flow of gas from a broken service line significantly reduces the risk of natural gas fire, explosion, personal injury and/or property damage.

You may request that GUC install an EFV on the gas line to your property. EFVs cannot be installed on some service lines due to high gas flow or other factors. If you request an EFV but your service line cannot accommodate an EFV we will let you know. If it becomes necessary to maintain or replace the EFV on your service line we will maintain or replace the EFV at no charge to you.

If you let us know that you want an EFV, we will contact you to set up a mutually agreeable date when we will install an EFV on your service line. Due to the increased safety functionality, the installation of the EFV will be completed at no cost to you.

For more information or to request the installation of an EFV, please contact the Gas Department at (252) 551-1587.
