If you smell gas right now

  1. Leave the house. Don’t switch lights or appliances on or off, and don’t use a lighter or match.
  2. Don’t try to stop the leak or repair a damaged pipe or meter yourself.
  3. From outside, call SoCalGas at 1-800-427-2200, or 911 if anyone could be in danger.
  4. After SoCalGas has made it safe, call us to find and fix the leak on your side of the meter.

Where SoCalGas’s pipe ends and yours begins

SoCalGas maintains its lines up to the meter. Everything after the meter, including the piping to each appliance and any buried line to a pool heater or barbecue, belongs to the property owner. The numbers show where leaks usually start.

  2. 2
    Threaded fittingsJoints in the house piping, often in a crawlspace or attic. They loosen with age, settling and earthquakes.

Signs of a gas leak

A rotten-egg smell

Natural gas has no smell of its own. The utility adds one so leaks can be noticed. If you smell it indoors, leave and call SoCalGas first.

Leave and call

Hissing near a line or appliance

A steady hiss or whistle near the meter, a connector or a valve usually means gas escaping under pressure.

Leave and call

A dead patch over a buried line

Plants or grass dying in a strip between the meter and a barbecue or pool heater can point to a leak underground.

Call us

Bubbles in wet ground

Bubbling in puddles or wet soil along the path of a buried line, with no other explanation.

Call us

A higher gas bill

A jump in usage with no change in how you use gas can be a small, steady leak.

Have it checked

How we find and fix it

  1. Confirm and isolateWe check the meter with everything off and close appliance valves one at a time to narrow it down.
  2. LocateAn electronic gas detector and leak-detecting solution on fittings and connectors; a pressure test on buried runs.
  3. RepairWe replace the failed connector, valve, fitting or section of pipe, with a firm price before we start.
  4. Test and restoreWe test the repaired piping, meet the inspector when a permit is required, and get the gas back on.

Common causes, and what we do about them

What we findWhat we do
Old uncoated brass appliance connectorReplace it with a stainless steel or plastic-coated connector. The CPSC recommends replacing any uncoated brass connector.
Loose or cracked threaded fittingRemake or replace the joint and test it.
Leaking appliance shutoff valveReplace the valve.
Corroded buried line to a barbecue or pool heaterReplace the run rather than patch it. Corrosion rarely stops at one spot.
Piping strained by earthquake movement or settlingInspect the whole system, repair the damaged section, and add a seismic shutoff valve if there isn’t one.

If you’re adding a gas line for a new appliance, a kitchen remodel or an outdoor kitchen, that’s covered on our gas line repair and installation page.

Seismic gas shutoff valves in Los Angeles

Under LAMC §94.1216.2, any building with gas piping needs a seismic gas shutoff valve or an excess flow shutoff valve when it is sold, or when a building permit over $10,000 is issued. A seismic valve shuts off gas at the meter when the ground shakes hard enough; an excess flow valve closes when gas flow jumps, as it would with a broken line. Either one satisfies the rule.

The valve has to be installed under an LADBS permit and inspected. If you’re selling, it’s worth doing before escrow so it doesn’t hold up closing. We install both types.

Permits and testing

Most gas piping repairs and replacements in the City of Los Angeles go through the Department of Building and Safety with a permit and inspection. The California Plumbing Code (§1213) requires repaired piping to be tested before it goes back into service; very small fitting repairs can be checked with leak-detecting solution instead of a full pressure test. We pull the permit when one is required, test the work, and meet the inspector. Unpermitted gas work tends to surface later, often during a sale.

Gas leak questions

What should I do if I smell gas in my house?

Leave first. Don’t turn lights or appliances on or off, don’t use a lighter, and don’t try to fix or shut off a damaged pipe or meter yourself. From outside, call SoCalGas at 1-800-427-2200, or 911 if anyone is in danger. Once SoCalGas has made it safe, call us to find and repair the leak on your side of the meter.

Who is responsible for the gas line after the meter?

You are. SoCalGas maintains its lines up to the meter. Everything after it belongs to the property owner, including the piping to each appliance and buried lines to a pool or spa heater or barbecue. SoCalGas recommends having those lines inspected periodically for corrosion and repairing unsafe conditions right away.

Will SoCalGas fix a gas leak inside my house?

SoCalGas will respond to make the situation safe, which can mean shutting off gas to an appliance or the whole house. Repairing piping on your side of the meter is the owner’s job and is done by a licensed contractor. Once the repair passes, the gas can be turned back on.

How do you find a gas leak?

We check the meter for movement with everything off, close appliance valves to isolate sections, then use an electronic gas detector and leak-detecting solution on fittings and connectors. For buried lines we pressure-test the run. We show you where the leak is before we quote the repair.

Do I need a permit to repair a gas leak in Los Angeles?

Most gas piping repairs and replacements go through the Los Angeles Department of Building and Safety with a permit and inspection. The California Plumbing Code (§1213) requires repaired piping to be tested; very small fitting repairs can be checked with leak-detecting solution instead of a full pressure test. We pull the permit when one is required and meet the inspector.

Do I need a seismic gas shutoff valve to sell my house in Los Angeles?

Yes. Under LAMC §94.1216.2, when a building with gas piping is sold, or a permit over $10,000 is issued, it needs either a seismic gas shutoff valve or an excess flow shutoff valve. The valve is installed under an LADBS permit and inspected. We install both types.

Is my old flexible gas connector dangerous?

It can be. The Consumer Product Safety Commission warned that older, uncoated brass connectors, used mostly on ranges, ovens and dryers, can fail where the fittings were soldered on. It recommends replacing any uncoated brass connector with a new stainless steel or plastic-coated one, and having a professional do it rather than moving the appliance yourself.

How long will I be without gas?

It depends on what failed. A leaking connector or fitting is often repaired and tested in one visit. A corroded buried line takes longer, and if a permit inspection is required, the gas stays off until it passes. We tell you the expected timeline when we quote.
