What Are Seismic Gas Shut-off Valves?

Seismic activity can quickly disrupt your home’s foundation. When an earthquake strikes and causes damage to pipes, it’s critical to restrict the flow of natural gas in order to prevent damage to your Southern California home and your health. Seismic gas shut-off valves, also called gas shut-off valves, earthquake gas shut-off valves, or earthquake valves, automatically shut off your natural gas service to prevent deadly gas leaks and their consequences. They’re typically installed on the exterior of your home or business, right after your city’s gas meter, before your gas line enters your home.

Two common types of specialized gas shut-off valves include:

Seismic Natural Gas Shut-Off Valve: When an earthquake of a sufficient size is detected, the valve will immediately shut off your natural gas service.
Excess-Flow Valve: The earthquake shut-off valve will shut off your natural gas service when a significant leak or overpressure surge occurs at a pipe, or where an appliance is located beyond the location of the valve installation.

Why Should I Install an Earthquake Shut-Off Valve?

In the event of a seismic earthquake of 5.1 or higher, your seismic valve will automatically close your gas line, even when you’re not home.
A shut-off valve will save your home from fires and damages when resources are most strained during and in the aftermath of an earthquake.

A natural gas leak means a dangerous and potentially deadly situation for you and your family. Without an earthquake shut-off valve, make sure you know how to recognize and respond to a gas leak in your home or business!

Do I Need An Earthquake Shut-Off Valve?

If you live in the state of California in a home that is newly constructed as of 2000, yes! According to seismic gas shut-off valve requirements in California, law enforcement agencies will enforce their installation before issuing a building permit to new homes or businesses.

If your home or business is older, it’s still highly recommended to have earthquake gas shutoff valves in place even though it isn’t illegal to be without one.
