Earthquake gas shutoff valves are required by Los Angeles building code for most new construction, major renovations, and property sales since 1998. Pacific Line installs, inspects, tests, and resets Pacific Valve, Seismic Safety Products, and Little Firefighter valves across Los Angeles and San Diego. From $389 installed. Post-earthquake reset service available 24/7.
An earthquake gas shutoff valve is a mechanical device installed on your gas meter that automatically closes when it detects seismic activity above approximately 5.2 magnitude. This prevents gas from flowing through potentially damaged gas lines after an earthquake — reducing the risk of fire or explosion.
Los Angeles Municipal Code requires earthquake gas shutoff valves on most new construction, major renovations, and property sales since 1998. After any earthquake, a licensed plumber must inspect your gas lines before resetting the valve.
Whether you need a new valve installed for a property sale, an inspection for peace of mind, or a reset after an earthquake — we handle every aspect of earthquake gas valve service.
We install earthquake gas shutoff valves at your gas meter — Pacific Valve, Seismic Safety Products, or Little Firefighter. Installation includes the valve, labor, LADWP permit, and inspection coordination. Most installations take 2–3 hours.
We inspect your existing earthquake valve to confirm it's functioning correctly, hasn't been damaged or tampered with, and will activate properly during seismic activity. We recommend inspection every 5 years.
After an earthquake, your gas valve has automatically closed. We inspect your gas lines for damage, confirm no leaks, and reset the valve to restore gas service safely. Available 24/7 after seismic events.
If your earthquake valve is damaged, corroded, or past its service life, we replace it with a new code-compliant valve. Installation includes removal of the old valve, new valve, permit, and LADWP inspection coordination.
We install all three earthquake gas shutoff valve brands approved by the Los Angeles Department of Building and Safety. Each brand has different sensitivity settings and reset mechanisms — we recommend the right brand based on your property type and gas meter location.
The most common earthquake valve brand in Los Angeles. Mechanical design activates at approximately 5.2 magnitude. Manual reset required after activation. 20+ year lifespan with proper maintenance.
Higher sensitivity than Pacific Valve — activates at lower magnitude earthquakes. Preferred for properties in high-risk seismic zones or properties with older gas lines. Manual reset required.
Compact design for properties with limited gas meter space. Same activation threshold as Pacific Valve (~5.2 magnitude). Preferred for properties with tight meter enclosures or complex gas line configurations.
Every earthquake gas valve service is quoted flat-rate in writing. Permit and LADWP inspection coordination included in every installation.

Yes. Los Angeles Municipal Code requires earthquake gas shutoff valves on most new construction, major renovations, and property sales since 1998. If your property was built or significantly renovated after 1998, it likely already has one.
If your property is older and you're selling, you may be required to install one before closing. We can inspect your property and confirm whether installation is required.
Yes. Earthquake gas shutoff valves automatically close when they detect seismic activity above approximately 5.2 magnitude. After any earthquake, you must have a licensed plumber inspect your gas lines for damage before resetting the valve.
We offer post-earthquake reset service — we inspect the gas lines, confirm no damage, and reset the valve so your gas service is restored safely. Available 24/7 after seismic events.
We install all three major brands approved by the LA building code: Pacific Valve (the most common in LA), Seismic Safety Products (SSP), and Little Firefighter.
Each brand has different sensitivity settings and reset mechanisms. We recommend the right brand based on your property type, gas meter location, and local code requirements.
Standard residential earthquake gas shutoff valve installation is $389 flat-rate, including the valve, labor, LADWP permit, and inspection coordination. Most installations take 2–3 hours.
Commercial installations and properties with complex gas line configurations are custom-quoted based on scope.
LA building code does not require regular testing of earthquake gas shutoff valves — they're designed to activate only during seismic events. However, we recommend having your valve inspected every 5 years to confirm it's functioning correctly and hasn't been damaged or tampered with.
This is included in our Professional and Enterprise maintenance contracts.
Technically yes — most valves have a manual reset mechanism. However, LA building code requires a licensed plumber to inspect your gas lines for damage before resetting the valve after an earthquake.
Resetting without inspection could allow gas to flow through damaged lines, creating a fire or explosion risk. We offer post-earthquake reset service at $189 flat-rate — we inspect, confirm no damage, and reset the valve safely.
