You can request installation of an excess flow valve. Gas appliances are connected to the gas supply by what is known as a flexible connector. The connector can develop leaks and cause unsafe conditions if stretched too far or bent too frequently.

Customers may request installation of an excess flow valve (EFV), a safety device that slows the flow of natural gas in the event of a service line break.

An EFV is not required for normal operation of your gas line. In fact, you may already have an EFV installed.

Please note, even if you request installation, certain conditions must exist for installation and there is a charge for this service.

For more information, we encourage you to visit nationalgridus.com/safety, then select the pipeline safety link located under the safety tab, and scroll down to the information on EFV.

Service line inspections keep our system safe. Customers may request installation of an excess flow valve (EFV), a safety device that slows the flow of natural gas in the event of a service line break.

National Grid's number one priority is safety. New York State recently passed a law requiring National Grid to inspect natural gas meters and associated piping. The no-cost inspections make sure all natural gas services are working properly and safely.

Prior to the start of inspections you will receive notification in the mail. When you receive notification, please follow the instructions to set this vital appointment at a time that is convenient for you.

Our contractors, RECONN (formerly known as Premier) and PPS (Precision Pipeline Solutions), will carry out the inspections. As a reminder, all National Grid contractors carry identification cards.

Use your senses to detect a gas emergency.

Gas leaks are often recognized by:

  • SMELL: Natural gas is odorless. A pungent odor similar to rotten eggs is added so you can detect it fast.
  • SIGHT: Outdoors you may see a white cloud, mist, fog, and bubbles in standing water. You may see blowing dust and vegetation in the area may appear to be dying.
  • SOUND: You may hear an unusual noise like roaring, hissing or whistling.

What to do next:

If you smell gas, move to a safe area outside, including pets, and call 911 or 1-718-643-4050. Never assume someone else will call.

Call 811 before you dig. Take these precautions while using a gas oven:

Any time you (or a professional) plan landscaping that involves digging, call 811 at least two full working days prior to the start of your project not including weekends, holidays, and the day you called. Even if you think you know where pipes might be, landscaping changes and erosion may shift pipe locations.

Calling 811 is not only the right thing to do — it’s the law and it's free.

After you call, representatives survey the area and mark existing underground utilities. This prevents unintended consequences, such as damage to natural gas and water pipes, service outages, personal injuries, potential fines and costly repairs.

Helpful tips to maintain outdoor gas appliances.

Helpful tips to maintain outdoor gas appliances. Natural gas grills, patio heaters, fire pits and fireplaces, require regular inspection, cleaning and maintenance.

  • Have a certified contractor run a gas line to your backyard porch or patio.
  • Keep all natural gas outdoor appliances away from the sides of your house or any building.

For grills remember:

  • Always start with a clean grill.
  • Check the metal tubes that extend under each burner for signs of spiders and insects which like to nest in the tubes. This can block the gas flow and cause a fire. Look for models with spider guards to prevent this problem. Clean regularly.
  • Make sure the gas grill is turned off or disconnected before cleaning.
  • Use a small flexible brush to remove debris from the metal tube and a thin wire to gently clean the holes or ports of each burner. Never use a toothpick.

Summer is perfect for a heating checkup.

Regular maintenance of your heating system keeps it running safely and efficiently, while ensuring continued comfort throughout the year.

During a checkup, your repair professional may:

  • Inspect and clean blower assembly (blower housing, blower wheel and motor).
  • Lubricate motor and inspect and replace fan belt on older models.
  • Inspect evaporator coil, drain pan and condensate drain lines. Clean as needed.
  • Inspect for leaks in gas furnaces.
  • Inspect burner assembly — clean and adjust as needed.
  • Inspect ignition system and safety controls — clean and adjust as needed.
  • Inspect heat exchanger or heating elements.
  • Inspect flue system — check for proper attachment to the furnace, dislocated sections, and signs of corrosion. Replace if necessary.
  • Inspect control box, associated controls, wiring and connections.
  • Clean or replace air filter.
  • Inspect conditioned airflow system (ductwork) — check for leaks.

Finally, follow up with National Grid if any unusual odors are detected. Make sure carbon monoxide detectors are working. Replace batteries annually.
