Precision Leveling
Aligning the valve internal sight glass with a precision machinist level so false trips from passing trucks are prevented.
Pressure Gauge Testing
Conducting an airtight mechanical pressure test to confirm that all threaded joints satisfy California Plumbing Code regulations.

Why Earthquake Gas Shutoff Valves Matter in Hanford
While Kings County sits in the agricultural heart of the Central Valley, Hanford is flanked by active regional fault systems including the San Andreas Fault to the west and the White Wolf and Sierra Nevada fault complexes to the south and east. Historic regional tremors, such as the 1983 Coalinga earthquake, caused severe ground motion across Kings County structures.
During an earthquake, rigid interior black iron pipes often remain intact, but older appliance flex connectors and water heater supply lines pull taut and shear. If an unanchored water heater shifts only four inches, the raw gas line can rip completely open. Without an automatic seismic valve, pressurized gas pours into the dwelling until someone locates a wrench and turns off the meter outside. Installing a seismic gas valve Kings County unit guarantees immediate fuel shutoff at the exterior meter riser the moment strong shaking occurs.
How We Handle It Step by Step
Proper seismic valve installation requires exact mechanical alignment and rigid stabilization:
-
Meter & Manifold Evaluation
Contractors examine house-side pipe clearance, verify meter outlet threads, and check wall backing stability.
-
Rigid Structural Stabilization
A seismic valve must be anchored firmly to the foundation or exterior stud wall using zinc-coated unistrut brackets so it reads true ground acceleration.
-
Plumb Level Valve Installation
The valve body is threaded onto the line with CSA gas sealant, perfectly leveled vertically and horizontally.
-
Pressure Testing & Reset Demonstration
Crews conduct high-pressure gauge tests and demonstrate the manual earthquake gas valve reset procedure for the property owner.

How to Find, Test and Reset Your Earthquake Valve
Certified seismic valves feature a sight glass on the valve exterior displaying green when the valve is open and red when tripped closed:
Resetting Your Seismic Valve Safely:
- Smell for Gas First: Before resetting the valve, walk around the home. If you smell rotten egg odors or hear hissing, do not reset the valve. Evacuate and call SoCalGas immediately.
- Locate the Reset Mechanism: Find the slotted reset screw or rotating knob on the valve side.
- Turn Slowly: Insert a flat-head screwdriver and rotate the reset screw one-quarter turn clockwise until you feel the internal steel ball seat onto its cradle.
- Verify the Sight Glass: Check the indicator window. It should change from red to green, confirming gas flow is restored.
- Relight Appliance Pilots: Safely relight water heater and furnace pilot lights following manufacturer guidelines.
Illustrative Service Scenarios

Safety for Your Family, Pets and Home
An earthquake gas shutoff valve acts as your home's automated guardian, operating mechanically without electricity or battery backups. When an earthquake triggers the valve, it stays closed until someone manually inspects the piping and resets the mechanism.
If a severe earthquake damages utility distribution mains in the street, SoCalGas may isolate entire neighborhood blocks. Always follow utility updates and never tamper with the street-side utility meter cock.

Frequently Asked Questions
Do I need an earthquake shutoff valve in Hanford?
While Kings County does not currently mandate seismic valves for all existing single-family homes, many insurance providers and home buyers strongly recommend them due to nearby Central Valley fault activity.
Will an earthquake valve shut off from small bumps?
No. Certified seismic valves are calibrated to trigger only during significant ground motion, typically equivalent to a 5.1 magnitude or greater earthquake at the pipe site.
Can I reset the earthquake valve myself?
Yes. Once you have verified that no gas lines are leaking, most certified valves can be reset by turning the manual reset screw with a flat-head screwdriver.
