FLOW VALVE NOTICE
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, due to 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.
may request that City of Buford 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 and
the cost of installation and maintenance.
EFVs cannot be installed on some service lines due to high gas flow, low
pressure or other factors. EFVs are not
designed to close if a leak occurs beyond the gas meter (on house piping or
appliances). EFVs also may not close if the leak on the service line is
small. And, if you add additional gas
appliances, for example, a pool heater, emergency generator, etc., the
additional gas flow may cause the EFV to close.
If you request an EFV we will inform you if your service line cannot
accommodate an EFV.

you make the final decision that you want an 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 it becomes
necessary to replace the EFV on your service line you will be billed
$500-$1,000, actual installation cost will depend on the difficulty of
