Dear Natural Gas Customer,


Excess Flow Valves (EFV’s) are mechanical shut-off devices that can be installed in the gas pipe running to the gas meter at your property (the “service line”). An EFV is designed to stop the flow of gas if the service line is broken, 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.

EFV’s are not designed to close if a leak occurs beyond the gas meter (on house piping or appliances). EFV’s also may not close if the leak on the service line is small.

EFV’s are currently required for all new or replaced gas service lines serving single family residences.

You, as an existing customer, have the right to request the installation of an EFV on your existing service line if one is not already installed. A representative of the gas department will come to your location and assess your service line to determine if the installation is possible. Should you decide to have an EFV installed, we will install the EFV and repair your yard for $500.

If you would like to have a representative inspect your gas services to see if you are a candidate for having an EFV installed, please call our office at: (662) 893-5209.
