To All customers: This notification is to provide you with information about a safety device called an Excess Flow Valve (EFV). This device meets the performance standards of 49 CFR 60110(e). Congress has mandated installation of excess flow valves in all new and renewed single-residence gas service lines. Branch service lines, (service lines which feed more than one residence) are not required to be equipped with excess flow valves.

The EFV is installed on the new service line near the gas main. The excess flow valve is designed to shut off the flow of natural gas automatically if the service line breaks between the gas main and the meter. The device works in much the same way as a circuit breaker in an electrical circuit. However, it is not designed to shut off the flow of gas if a line breaks at the connection of an appliance in the residence or on the customer piping (interior or exterior) on the customer side of the gas meter. The EFV is designed to shut off the gas from the main if the City’s service line is accidently damaged by a contractor or an individual working in your yard. These people are already required by law to notify the City of Leesburg Gas Department through the Sunshine One Call system, prior to excavation, so that the gas lines can be located. The EFV is just an added safety device.

The cost of the EFV for a standard ¾” or 1” residential service line is $60.00 if installed during the initial installation of the gas service. The cost of the installation for established services will be determined by using time and material estimates. The EFV will be installed by and remain the property of the City of Leesburg. Any future maintenance or replacement costs will be the responsibility of the customer and will be determined at that time.

If we can answer any questions regarding this notice, please give us a call at 352-728-9840.

Thank you, City of Leesburg Natural Gas Department
