Full Details: EFV Installation


Maintain and use your gas appliances safely.

Good maintenance and proper use of all your gas appliances is essential to prevent exposure to carbon monoxide and fire hazards. For your safety, follow these steps:

Have your gas appliances inspected annually by a licensed heating or plumbing contractor.

Have a qualified, licensed contractor perform all gas appliance and venting repairs.

Never store or use flammable products in the same room as or near any gas or heat-producing appliances. Flammable products include: gasoline, spray paints, solvents, insecticide, adhesives, foggers, varnish, cleaning products and other pressurized containers. This will reduce the risk of flammable vapors being ignited by the main burner flame found in all gas appliances or the pilot flame found in many gas appliances. 

If a burner flame is yellow, large, and unsteady, the appliance needs to be inspected immediately by a qualified professional.

Never store anything near a gas appliance that might interfere with normal appliance airflow.

Ensure that gas appliance intake and exhaust vents are clear of obstructions.

When operating vented decorative gas logs, open the fireplace/chimney damper completely.

Never use your oven, range or outdoor barbecue to heat your home. These appliances are not designed for this purpose.

An EFV is a mechanical safety device installed in a natural gas service line between the natural gas main and the natural gas meter.

EFVs minimize or stop the flow of natural gas in the event of a service line break.

EFVs will not work properly on all natural gas services; therefore, not all customers qualify for an EFV.

You may choose to have an EFV installed on your service line
Installation of an EFV is optional. Costs vary and are the responsibility of the customer. Residential costs are likely to exceed $500.  Commercial costs are likely to exceed $1000, but will vary depending on the complexity of the installation. A quote will be provided upon request.

Quick Facts:

  • Most residential customers with service lines installed after 2009 have an EFV included on their service line.
  • EFV's can not be installed on some service lines due to high gas flow, low pressure or other factors.
  • EFV's are not designed to close if a leak occurs beyond the gas meter on house-piping or appliances, or if the leak on the service line is small.
