You may request that M.U.D. install a mechanical shut-off device called an excess flow valve (EFV) on the natural gas service line to your property. An EFV is designed to significantly reduce the flow of gas if the service line outside of the structure becomes damaged, lessening the possibility of a natural gas fire, explosion, personal injury and/or property damage.
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.
EFVs are NOT designed to close if a leak occurs beyond the gas meter (on house piping or appliances). EFVs also may not close if the leak on the service line is small. If you add gas appliances, like a pool heater or emergency generator, there is a possibility that the additional gas flow may cause the EFV to close.
If you notify us that you want an EFV, we will contact you to set up a mutually agreeable date when we will install it. You will be responsible for the installation cost of $800 (installment plans are available).
Note: EFVs cannot be installed on some service lines due to high gas flow, low distribution system pressure or other factors. Each situation will be evaluated upon request.
