Beginning April 14, 2017 a new regulation will require all natural gas utilities to notify customers about excess flow valves (EFV) and install an EFV if the customer requests one.

You may request that The Town of Trion install an excess flow valve (EFV) on the gas line to your property. EFV’s are mechanical shut-off devices that can be installed in the gas pipe running to the gas meter at your property (the “service line”). An EFV is designed to significantly reduce the flow of natural gas automatically if the service line is broken, 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.

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 notify us that you want an EFV, we will inspect your service and determine the feasibility and cost for installation. The cost for installation will vary with each service depending on difficulty (such as line under asphalt, concrete, etc). Once an installation cost has been determined, we will contact you to set up a mutually agreeable date when we will install an EFV on your service line.

EFV replacement may be necessary if you add additional gas appliances, such as a pool heater or emergency generator that exceeds the capacity of the EFV. If it becomes necessary to replace the EFV on your service line due to increased load, you will be responsible for the installation cost of the new EFV.

EFV replacement may be necessary if the EFV malfunctions (sticks open or closed). You will not be billed if the EFV malfunctions. Industry experience is that EFVs rarely malfunction.

EFVs will not be installed on your service lines if:

  • The EFV could interfere with proper operation or cause loss of service;
  • An EFV could interfere with necessary operation or maintenance activities; or
  • The capacity of the meter on the service line exceeds 1,000 cubic feet per hour

If you request an EFV we will inform you if your service line meets any of these conditions.

For your safety always call 811 to have gas lines and other buried utilities marked before allowing anyone to dig in your yard.
