Excess Flow Valves

Excess Flow Valves (EFVs) are mechanical shut-off devices that can be installed in the natural gas pipe running to the gas meter at your property (the "service line").

An EFV is designed to shut off most of the flow of natural gas automatically if the service line breaks, 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 we install an excess flow valve on the service line to your property. If you notify us that you want an EFV, we will contact you to discuss your specific situation of installation and maintenance. EFV s cannot be installed on some service lines due to high gas flow, low pressure or other factors. If you request an EFV, we will inform you if your service line cannot accommodate an EFV. 

If an EFV can be installed on your service line and you choose to have this done, we will set up a mutually agreeable date when we will install an EFV on your service line. 

You will need to request and pay $800.00 or $1500.00 to cover the cost of installing the EFV. 

To submit a request or if you have questions, please call the City Of Covington Customer Service Department at 770-385-2000.
