Excess Flow Valves

Federal regulations (49 CFR 60110(e)) requires installation excess flow valve safety devices 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 - installed on the new service line near the gas main - 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 will 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 so that the gas lines can be located prior to digging.

The cost of the EFV for a standard ¾” or 1” residential service line is $60 if installed during the initial installation of the gas service. The cost of 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. Contact us for more information at (352) 728-9840.
