Seismic gas shut-off valve installation in Santa Clara — trusted by local homeowners and contractors.

What Is a Gas Earthquake Shut-Off Valve?
A gas earthquake shut-off valve is a mechanical safety device that automatically shuts off your home’s gas supply if an earthquake of magnitude 5.2 or higher is detected. Installed on your gas meter or main line, this valve prevents fires, leaks, and explosions caused by seismic damage to gas pipes and fittings.

In a city like Santa Clara, which sits in an active seismic zone near the Hayward Fault, this simple upgrade is a powerful safety measure. Once triggered, the valve closes the gas line and remains shut until a licensed technician inspects your system and manually resets the valve to ensure it’s safe to use.

Why Santa Clara Homeowners Are Installing Seismic Gas Valves:
• Prevents hazardous gas leaks during and after an earthquake
• Automatically shuts off your gas without any power or user input
• Complies with Santa Clara city and county building codes
• Often required for remodeling, ADUs, or new gas service connections
• May help lower your homeowner’s insurance premiums
• Enhances property value and disaster readiness

How the Valve Works:
1. Seismic Motion Detected
A calibrated internal sensor detects ground shaking that exceeds a specific magnitude threshold.
2. Automatic Shut-Off
The valve immediately stops the flow of gas to protect your home from leaks, fires, or explosions.
3. Manual Reset After Inspection
A licensed plumber conducts a thorough inspection and resets the valve only after verifying system safety.
