Rosemont sits in earthquake country, and we’ve seen what happens when gas lines fail during seismic events. That’s why we only install DSA-certified valves and follow manufacturer specifications exactly.
We start with a site evaluation to determine the right valve type for your gas meter setup. California requires specific placement downstream of your utility meter, and we’ll identify the optimal location.
Installation typically takes 2-3 hours. We shut off your gas supply, install the certified seismic valve according to manufacturer specs, and test the system thoroughly. Your gas service is restored the same day.
We handle all permits and inspections required by local building departments. You get documentation showing compliance with California safety standards, plus warranty information for your 30-year coverage. No surprise fees, no commission-based upselling.

California law requires earthquake shut-off valves for new construction and major renovations. Many insurance companies now require them for coverage. If you’re selling your home, buyers often expect seismic safety measures in place.
Rosemont’s proximity to active fault systems makes earthquake preparedness essential. We install both seismic valves (triggered by ground motion) and excess flow valves (triggered by sudden gas flow increases). Many homeowners choose both for maximum protection.
All valves must be DSA-certified and installed by licensed contractors. DIY installation voids warranties and may not meet insurance requirements. Our installations include proper mounting, correct sensitivity settings, and reset instructions for after-earthquake situations.
Seismic valves detect earthquake motion and automatically shut off gas flow when ground movement reaches a certain intensity, typically around magnitude 5.1 or higher. They’re designed to prevent gas leaks caused by pipe damage during earthquakes.
Excess flow valves detect sudden increases in gas flow rate, which indicates a major leak downstream. They shut off gas when flow exceeds normal usage patterns, protecting against breaks in your home’s gas lines.
Many homeowners install both types for comprehensive protection. Seismic valves prevent earthquake-related leaks, while excess flow valves catch other types of gas line failures. Both require professional installation and DSA certification in California.
Yes, California requires earthquake shut-off valves for new construction since 2000 and for major renovations over $10,000. Many local jurisdictions have additional requirements, and some require them for home sales.
Insurance companies increasingly require seismic shut-off valves for coverage in earthquake-prone areas. Even if not legally required for your specific situation, they’re often necessary for insurance compliance or home sale requirements.
All valves must be state-certified and installed by licensed plumbing contractors. Only DSA-approved models meet California standards, and improper installation can void warranties and insurance coverage.
Professional installation typically costs between $400-800 depending on your gas meter setup and valve type. This includes the certified valve, professional installation, permits, and testing.
The investment pays for itself through insurance discounts, increased home value, and most importantly, family safety. Many insurance companies offer premium reductions for homes with certified seismic safety equipment.
We provide upfront pricing with no hidden fees. Our quotes include everything needed for compliant installation, so you won’t face surprise costs during the job.
After an earthquake activates your seismic valve, gas flow stops immediately to prevent leaks. The valve must be manually reset before gas service can resume, but only after a safety inspection.
We recommend having a qualified professional check your entire gas system before resetting the valve. This includes inspecting all gas appliances, connections, and lines for earthquake damage that could cause leaks.
Some jurisdictions allow homeowners to reset their own valves after proper inspection, while others require professional service. We provide reset instructions and are available 24/7 for post-earthquake service calls.
California-certified earthquake shut-off valves come with 30-year warranties and are designed for decades of reliable operation. They’re built to withstand multiple earthquake activations without losing effectiveness.
Regular maintenance isn’t typically required, but we recommend annual visual inspections to ensure the valve hasn’t been damaged or obstructed. The sensing mechanism should remain clear and properly mounted.
If your valve activates during an earthquake, it can be reset and will continue protecting your home. These aren’t one-time-use devices – they’re engineered for multiple activations over their 30-year lifespan.
California law requires licensed plumbing contractors to install seismic gas shut-off valves. DIY installation is prohibited and will void warranties, violate building codes, and potentially invalidate insurance coverage.
Professional installation ensures proper valve selection, correct mounting, appropriate sensitivity settings, and compliance with local building codes. Licensed contractors understand gas line safety and proper installation techniques.
We handle all permits, inspections, and documentation required for legal compliance. Our installation includes testing and certification that your valve meets California safety standards and manufacturer specifications.
