Excess Flow Valves (EFV’s) are mechanical shut-off devices that can be installed in the natural gas pipe running to the gas meter at your property (the service line). An EFV is designed to shut off most of the flow of natural gas automatically if the service line breaks, for example, by an excavation accident. Stopping the flow of gas from a broken service line significantly reduces the risk of natural gas fire, explosion, personal injury and/or property damage.

You may request that Jointly Owned Natural Gas install an excess flow valve on the service line to your property.

If you notify us that you want an EFV installed we will contact you to discuss your specific circumstances and the cost of installation and maintenance. There are certain conditions when EFV’s cannot be installed on some service lines due to the high gas flow, low pressure or other factors. If you request an EFV we will inform you if your service line can accommodate an EFV.

If an EFV can be installed on your service line and you choose to have one installed, we will set up a mutually agreeable date when we will install and EFV on your service line.

You will be billed the cost to install the EFV, depending on the specific circumstances associated with your service line and property, the cost would be between $1,000 and $1,500.

If, in the future, it becomes necessary to perform maintenance on or replace the EFV on your service line, you will be billed $750 per repair or replacement.

You are not required to have an EFV installed; this notification is intended only to make customers of Jointly Owned Natural Gas aware of their availability.
