What Is a Gas Earthquake Shut-Off Valve?

 

A gas shut-off valve is a mechanical safety device installed on your gas meter or gas line. When an earthquake of magnitude 5.2 or higher is detected, the valve automatically shuts off your home’s gas supply—stopping leaks before they become catastrophic.

 

Benefits:

 

• Prevents gas leaks, fires, and explosions

• Automatically activates during seismic events

• Meets many local building code requirements

• Adds safety, security, and peace of mind

 

Once activated, the valve stays closed until manually reset after a safety inspection.

 

 

How Does It Work?

 

Step 1: Earthquake Detected

The valve’s internal sensor reacts to seismic vibrations above a specific threshold.

 

Step 2: Automatic Shut-Off

The valve immediately closes the gas line, preventing leaks caused by broken pipes or fittings.

 

Step 3: Manual Reset

A licensed professional inspects your system and resets the valve after verifying everything is safe.

 

 

Why Install a Gas Seismic Shut-Off Valve?

 

• Prevents fires and explosions caused by gas leaks

• Protects lives and property during and after an earthquake

• May qualify for home insurance discounts

• Required in many cities for remodels and new construction

 

Earthquakes strike without warning. Installing a seismic shut-off valve is one of the smartest and most affordable safety upgrades available for homeowners.
