Shut-Off Valve Installation Process

Simple Installation, Lifelong Protection
We start by evaluating your gas meter location and determining the right valve type for your specific setup. Most residential installations use seismic shut-off valves that detect ground motion and automatically close when earthquake activity reaches preset levels. The installation happens at your gas meter, typically taking 2-3 hours for standard residential properties. We shut off your gas supply, install the valve between your meter and your home’s gas line, test the system thoroughly, and restore your gas service. You’ll see exactly how the valve works and when it activates. After installation, we walk you through the reset process so you know how to restore gas service after the valve has been triggered. We also provide you with documentation for your insurance company and local building department if required. The valve works automatically from that point forward—no maintenance needed from you.

Gas Leak Prevention Solutions

Complete Earthquake Safety Installation
Your installation includes the seismic shut-off valve, all necessary fittings and connections, professional mounting, and complete system testing. We use valves rated for California’s seismic conditions and install them according to local building codes. In Walnut Grove, soil conditions and proximity to fault lines mean your valve needs to be calibrated correctly for local earthquake patterns. We adjust sensitivity settings based on your specific location and the types of seismic activity most common in your area. Too sensitive, and you’ll have false shutoffs from minor tremors. Not sensitive enough, and the valve won’t protect you when it counts. We also inspect your existing gas lines during installation to identify any potential weak points that could become problems during seismic events. If we spot issues, we’ll let you know what needs attention and give you straight pricing on any additional work. Your safety system is only as strong as its weakest component.

How sensitive should my earthquake shut-off valve be set?

Most residential valves in Walnut Grove should trigger at 0.4 to 0.5g of horizontal acceleration. This setting prevents false shutoffs from minor tremors while ensuring activation during earthquakes strong enough to damage gas lines. We calibrate your valve based on your distance from major fault lines and local soil conditions. Sandy soil amplifies ground motion, so homes near the Sacramento River might need slightly less sensitive settings. Clay soil tends to dampen motion, so we might increase sensitivity slightly. The goal is protection during damaging earthquakes without nuisance shutoffs every time a large truck drives by. We test the calibration during installation and can adjust it if you experience issues.
Yes, earthquake shut-off valves are completely mechanical and require no electricity to function. They use the physical motion of the earthquake itself to trigger the shutoff mechanism. The valve contains a weighted ball or pendulum that moves when ground acceleration reaches the trigger point. This mechanical motion releases a spring-loaded mechanism that closes the gas flow. No batteries, no electrical connections, no dependence on power grid. This mechanical design means the valve works even during extended power outages that often follow major earthquakes. As long as there’s seismic motion above the trigger threshold, the valve will activate and stop gas flow to your home.
After an earthquake triggers your shut-off valve, you’ll need to manually reset it before gas service can resume. First, check for gas leaks around your home—if you smell gas, don’t reset the valve and call us immediately. If there’s no gas odor, locate the reset mechanism on your valve (usually a lever or button) and follow the manufacturer’s reset procedure. Turn your gas meter back on slowly, then relight pilot lights on water heaters, furnaces, and other gas appliances. We provide detailed reset instructions during installation and recommend keeping them posted near your gas meter. If you’re uncomfortable resetting the system yourself, we offer emergency service calls to restore your gas safely after seismic events.
Permit requirements vary by jurisdiction in Sacramento County. Most residential earthquake valve installations don’t require permits, but some local building departments want notification of the work. We handle permit research and filing for you when required. Our team knows which local jurisdictions have specific requirements and ensures your installation meets all applicable codes. This protects you during insurance claims and home sales. Some areas offer rebates or tax incentives for seismic safety improvements, including automatic shut-off valves. We can help you identify available programs and provide the documentation needed for rebate applications.
Earthquake valves respond to ground motion and shut off gas when seismic activity reaches dangerous levels. Excess flow valves respond to sudden increases in gas flow, like what happens when a gas line breaks or gets severed. For California homes, earthquake valves provide better protection because they activate before gas lines fail, preventing leaks from starting. Excess flow valves only respond after a leak has already begun, which might be too late if the leak ignites immediately. Many safety-conscious homeowners install both types for comprehensive protection. The earthquake valve prevents leaks during seismic events, while the excess flow valve provides backup protection against line breaks from other causes like construction accidents or tree root damage.
Quality earthquake shut-off valves typically last 20-30 years with minimal maintenance. The mechanical design has few moving parts and doesn’t wear out from normal use. We recommend annual visual inspections to ensure the valve housing remains secure and undamaged. Check that the reset mechanism moves freely and that there’s no corrosion around connections. Most homeowners can handle these basic checks themselves. Professional inspection every 5-10 years ensures the valve still triggers at proper sensitivity levels and that all connections remain gas-tight. If your valve has triggered during an earthquake, we recommend professional inspection before resetting to verify it will function properly in future seismic events.
