Excess Flow Valves

An Excess Flow Valve (EFV) is a safety device that can be installed on your natural gas service line (the underground line that runs from the main line to the meter).  Excess flow valves are designed to shut off or significantly reduce the flow of natural gas if a service line becomes damaged, and that damage causes a sudden and significant leak or pressure drop.  When activated, the excess flow valve may prevent the buildup of natural gas and may lessen the possibility of a natural gas fire, explosion, personal injury, and/or property damage.  However, they do not protect against leaks beyond the meter assembly (house piping).  A service line may be damaged by natural forces (such as seismic activity), excavation damage, or a vehicle hitting and severing a gas meter.

The Energy Cooperative has been installing EFVs on all new or replaced service lines meeting certain design requirements since early 2010 and will continue to do so.  As a safety enhancement to our members who have service lines installed prior to 2010, The Energy Cooperative is offering install an EFV at the member’s request for $750, to be paid by the member.  Members may be responsible for future EFV maintenance and replacement costs, which are unknown at this time.  In some instances, excess flow valves cannot be installed due to operating characteristics and limitations. Each situation will be evaluated upon request.

If you would like additional information on our EFV installation program contact us at (800) 255-6815 and ask to speak with someone about our excess flow valve program.  We can work with you to understand the EFV installation requirements and determine if the installation is right for your home.
