A recent federal regulation concerning gas pipeline safety requires Liberty Utilities to notify its customers of their right to request installation of an Excess Flow Valve (EFV) on their existing gas service line. An EFV is a mechanical safety device installed inside a gas service line between the gas main in the street and the gas meter. The EFV is designed to minimize the flow of natural gas in the event of a service line break.
A potential safety benefit is if an excavator accidentally digs up the gas service line, the valve would automatically minimize the flow of gas.
EFV Conditions & Information
EFVs do not operate on all gas service lines and certain parameters may exist where installation of an EFV is not warranted. Many customers already have an EFV installed on their existing service line. If you are interested and to determine if you are eligible to have an EFV installed on your gas service line:

Installation requires Dig Safe notification and excavation where the existing gas service line connects to the gas distribution main. Gas service will be interrupted to the customer. The cost of installing the EFV will be at the expense of the customer. Individual estimates will be provided upon request. The average standard cost of an EFV installation is estimated at $1500. The installation of an EFV will be scheduled at a mutually agreeable date pending the approval of city permits and weather conditions.
