Gas Line Repair & Earthquake Shutoff Valves in Los Angeles
Gas leaks are serious safety hazards. Our certified plumbers pinpoint gas leaks with electronic sniffers, replace corroded black iron lines, and install code-mandated automatic earthquake shutoff valves across LA.
Signs You Have a Dangerous Gas Line Leak
If you notice any of the following symptoms in your property, call our technicians for a clear evaluation:
Sulfur or Rotten Egg Odor
Gas utilities add mercaptan so even minute leaks can be detected by smell before reaching hazardous concentrations.
Hissing Sound Near Appliances
A distinct whistling or hissing noise near gas ranges, water heaters, furnaces, or pool heaters.
Dying or Brown Vegetation
Patches of dead grass or plants above underground yard gas supply lines to outdoor BBQs or fire pits.
Higher Than Normal Gas Bills
Unexplained spikes in monthly SoCalGas bills when appliance usage has remained constant.
Appliance Flame Color Changes
Yellow or orange lazy burner flames instead of crisp, steady blue flames indicating improper pressure or supply.
Earthquake Shutoff Valves: Motion vs. Excess Flow
Los Angeles Municipal Code mandates automatic gas shutoff valves for seismic defense:
Seismic Actuated Shutoff Valve (Motion)
- ✓Automatically trips when 5.4+ magnitude earthquake tremors occur
- ✓Prevents post-earthquake structural fires and gas line explosions
- ✓Manual reset mechanism once building safety is confirmed
- ✓Mandatory for all home sales and major remodels in City of Los Angeles
Excess Flow Gas Shutoff Valve
- ✓Automatically shuts off gas when sudden high-volume flow occurs
- ✓Triggers if a pipe shears, breaks, or appliance line disconnects
- ✓Does not require ground shaking to activate safety closure
- ✓Ideal supplementary protection for commercial kitchens & multi-units

Frequently Asked Questions About Gas Line Repair
Clear, direct answers to common questions from Los Angeles homeowners:
Is an earthquake gas shutoff valve required by law in Los Angeles?
Yes. The City of Los Angeles Ordinance #171874 mandates that an approved automatic earthquake gas shutoff valve (or excess flow valve) be installed on all residential and commercial buildings during property sales or major renovations exceeding $10,000.
What happens if SoCalGas shuts off my gas meter due to a leak?
When the gas company red-tags and locks your meter, you must hire a licensed C-36 plumbing contractor to repair the leak, perform a city-inspected pressure test, and provide certification before SoCalGas will restore service. We handle the entire process end-to-end.
Can I install or repair a gas line myself?
No. Gas line work carries severe fire and explosion risks and requires licensed trade permits in California. All gas piping must be tested and inspected to meet current UPC and LADBS codes.
How long does a gas line pressure test take?
A standard pressure test takes between 15 to 30 minutes under inspector observation, holding 10 to 15 PSI on a specialized diaphragm gauge.
What type of pipe is used for gas lines in Los Angeles?
We use heavy-gauge Schedule 40 black steel pipe for indoor lines and coated steel or specialized Polyethylene (PE) with tracer wire for buried underground yard runs.
