Effective April 14, 2017, in accordance with new federal regulation 49 CFR 192.383(e), Lexington Utilities Natural Gas Department offers the installation of an excess flow valve (EFV) on the gas line to your property. An EFV is a mechanical shut-off device that can be installed in the gas pipe running to the gas meter at your property (the “service line”), and is designed to shut off 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 reduces the risk of natural gas fire, personal injury and/or property damage. If you notify us that you want an EFV, we will contact you to set up an appointment to discuss installing an EFV on your service line.

Residential Customers who request that an Excess Flow Valve be installed on their natural gas service line will be billed, at a cost of $250. Commercial Customers will be billed the City’s actual construction cost for EFV or Customer Control Valve installation. If you wish to discuss further, please call 336-248-3945.

An Excess Flow Valve is not designed to close if a leak occurs beyond the gas meter (on house/customer piping or appliances). An EFV also may not close if the leak on the service line is small.

EFVs 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 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.

EFV replacement may be necessary if you add additional gas appliances, such as a pool heater or emergency generator that exceeds the capacity of the EFV. If this is the case, you may be charged a fee for EFV replacement.

For your safety, always call 811 to have gas lines and other buried utilities marked before allowing anyone to dig in your yard.
