Excess Flow Valve (EFV) Request

A natural gas service line is the piping connecting a customer’s meter to the natural gas main. An EFV is a device installed as part of a service line. The EFV provides a safety benefit by reducing or stopping the flow of natural gas if a service line is broken or is damaged by a home owner or excavating contractor.

UGI currently installs EFVs on most new customer service lines, as well as on service lines replaced as part of UGI’s facility replacement and betterment program. Customers who do not have an EFV on their service line may request one. Please be aware the installation of customer-requested EFVs will be done at the customer’s expense.

There is important information you should know regarding EFVs:

• Not all customer service lines qualify for an EFV installation. EFVs cannot be installed on some service lines due to high gas flow, gas system pressure, as well as other factors. UGI will determine whether or not a requesting customer’s service line is eligible for an EFV and will provide that information to you.
• EFVs will not activate at low flow rates and do not provide protection from appliance or fuel line problems.

Customers should be aware that retrofitting a service line with an EFV typically involves excavating the service line in or near the street. During the installation process, gas service will be temporarily disrupted while the EFV is installed. Please note the actual cost of installation will be determined by site conditions, and could range from $800 to $3000. The actual billable cost information will be provided to the customer prior to installation of the EFV.
