Federal law did not require EFVs to be installed on newly constructed homes until June 2008. If your home was built prior to June 2008, you most likely do not have an EFV installed on the service line to your home. Customers who want to have an EFV installed on their service line that was installed prior to June 2008 may do so at their expense.
You most likely already have an EFV installed if:
Your home/building was built since June 2008
Your gas service line was replaced since June 2008
You may call Customer Service at 402.554.6666 to verify if you have an EFV on your service line.
