Leak repair
Finding and repairing leaks at fittings, valves, flexible connectors and underground lines, then testing the system before service is restored.
From a corroded gas connector in a Peninsula garage to a new line for an outdoor kitchen in Newport Coast, gas work has to be sized right, tested and permitted. If you smell gas now, leave and call SoCalGas first.
If you smell gas, leave right away and call SoCalGas at 1-800-427-2200 from a safe place, or 911 if lives may be at risk. Once the utility makes it safe, a licensed plumber repairs the line or connector, pressure tests it and restores service through SoCalGas. New gas lines for appliances, fire pits and tankless heaters must be sized for the total load and permitted. Call (949) 620-1945.
SoCalGas says to evacuate the area immediately and call 1-800-427-2200 from a safe location. Call 911 from a safe location if a leak may endanger life.
SoCalGas responds to suspected leaks, shuts off gas if needed and makes the area safe. The repair of house piping, connectors and appliance valves on your side of the meter is plumbing work. That is where we come in. After the repair, the line is pressure tested and SoCalGas restores service and relights pilots.
Gas line plumbing covers everything between the meter and your appliances.
Finding and repairing leaks at fittings, valves, flexible connectors and underground lines, then testing the system before service is restored.
Replacing rusted gas risers, meter connections and flexible appliance connectors, especially on homes within a few blocks of the harbor and ocean.
Lines for gas ranges, dryers, furnaces and water heaters, including moving a range during a kitchen remodel.
Gas for fire pits, built-in barbecues, outdoor kitchens, patio heaters, pool and spa heaters. Common in Newport Coast, Corona del Mar and Dover Shores backyards.
Resizing the gas line, and sometimes coordinating a meter upgrade with SoCalGas, for a tankless conversion. See tankless water heaters.
Adding or replacing appliance shutoff valves so each appliance can be isolated for service.
Every gas appliance in the house shares the same supply, so a new appliance can starve the others if the pipe is too small.
Gas piping is sized by the total demand of all connected appliances and the length of the run. Add a tankless water heater, a pool heater and an outdoor kitchen to a line sized for a tank water heater and a furnace, and you can get weak burners, ignition faults and error codes. A tankless unit can draw several times the gas of a tank heater when it fires.
Before quoting new gas work, the plumber adds up the load, measures the run, and checks whether the existing line and meter can carry it. If the meter needs to be upsized, that is arranged with SoCalGas.
Exterior gas piping corrodes faster near salt water, and floodwater can reach gas appliances in low-lying garages.
On the Balboa Peninsula, Balboa Island, Lido Isle and Newport Island, gas risers, meter connections and exterior pipe live in salty, damp air. Rust at threaded joints and pitted pipe are common finds. Painting and protecting exterior gas pipe slows corrosion, and replacing badly rusted sections before they leak is far cheaper than an emergency call.
The City lists those same areas among the most flood-prone in town during king tides. If floodwater reached a gas water heater, furnace or dryer, leave it off and have it inspected before it is relit. Water can damage gas controls and burners. Our flood repair page covers the full post-flood check.
Strapped water heaters, flexible connectors and accessible shutoffs make gas systems safer in an earthquake.
Natural gas is odorized so you can smell it, but other signs can point to a leak or a combustion problem too.
Any time you suspect a leak, follow SoCalGas's guidance: leave the area and call 1-800-427-2200 from a safe place. Flame color and soot point to combustion problems that a plumber or appliance technician should check. A working carbon monoxide alarm near sleeping areas is a smart backup in any home with gas appliances.
Decide on every gas appliance up front, because the line is sized for the total.
Grill, side burners, fire pit or fire table, patio heaters, pool or spa heater, and anything you may add later.
The plumber compares the total demand with the meter and existing piping.
Underground runs avoid irrigation, the sewer lateral and other utilities. Everything is marked through 811 first.
Each appliance gets an accessible shutoff valve.
The line is pressure tested and inspected before it goes into service.
Near the water, choose corrosion-resistant fittings and protect any exposed pipe. Salt air on a harbor-side patio is hard on metal.
The short connector between the gas valve and the appliance is one of the most common places a gas problem starts.
Older homes sometimes still have uncoated brass connectors, which can crack at the flare fittings. Connectors that have been kinked, stretched, reused or exposed to salt and moisture should be replaced with new approved connectors sized for the appliance. When we replace a water heater, range or dryer, we check the connector and the shutoff valve and replace them if they are worn.
Some gas symptoms mean leave the house now; others mean book a repair this week.
| What you notice | Likely cause | What to do |
|---|---|---|
| Rotten egg smell indoors or at the meter | A gas leak | Leave, then call SoCalGas at 1-800-427-2200 from a safe place |
| Hissing near the meter, a pipe or an appliance | Gas escaping | Leave, then call SoCalGas or 911 from a safe place |
| A yellow, large or unsteady burner flame | Incomplete combustion | If safe, turn the appliance off, ventilate, and have it serviced |
| A pilot light that keeps going out | A worn thermocouple, a draft, or a dirty pilot | Book a repair; do not keep relighting it |
| Weak burners when the tankless heater or pool heater fires | An undersized gas line or meter | Have the total load calculated |
| Flaking rust on the riser or exterior pipe | Salt-air corrosion | Replace the section before it leaks |
| A gas bill that jumps with no change in use | A possible leak or an appliance problem | Have the system checked and pressure tested |
Carbon monoxide has no smell, so the warning signs are in your body and in the flame, not in your nose.
SoCalGas notes that California requires an approved carbon monoxide alarm for each sleeping area and on every level of the home, and that alarms need routine maintenance and replacement at least every three to five years. California's law took effect July 1, 2011 for single-family homes with an attached garage or a fossil fuel source. Many Peninsula and Balboa Island homes have the gas water heater in an attached garage, so a working alarm matters there. An alarm is a backup, not a substitute for appliance maintenance.
New or repaired gas piping is pressure tested before it is put into service, and the California Plumbing Code sets the minimums.
| System | Minimum test pressure | Minimum time |
|---|---|---|
| Standard gas piping (air, CO2 or nitrogen test) | 10 psi gauge | 15 minutes, no perceptible drop |
| Welded piping, or gas above 14 inches water column | 60 psi | 30 minutes |
| CSST carrying gas above 14 inches water column | 30 psi | 30 minutes |
The Authority Having Jurisdiction, here the City of Newport Beach Building Division, sets how long the test is held beyond those minimums. The inspector checks the gauge before the line goes live.
Corrugated stainless steel tubing, often yellow-jacketed, is common on newer appliance runs. CPC section 1211.2 requires it to be bonded with a jumper no smaller than 6 AWG copper wire, connected to a metallic pipe or fitting, and no longer than 75 feet to the grounding electrode system. If you have CSST and no visible bonding clamp, ask us to look.

The length of the run, trenching through pavers or concrete, the number of appliances, a meter upgrade with SoCalGas, and the permit all move the real number. You get a written price before any work starts. More figures are in our cost guide.
The neighborhood shapes the gas work as much as the appliance does.
Water heaters and dryers in garages near the harbor sit in salty, damp air. Flexible connectors, shutoff valves and the riser at the meter corrode first. After a king tide, any gas appliance that took water stays off until it is inspected.
Moving a range to an island or adding a professional range means a new gas run, sized for the larger burners and permitted with the remodel.
Outdoor kitchens, fire features and pool heaters often go in together, sometimes with a tankless water heater conversion. That combined load is where undersized lines and meters show up. HOA approval may be needed before trenching.
Fire pits and barbecue islands mean underground runs that cross irrigation lines and sometimes the sewer lateral. Every utility is marked through 811 first.
Most gas problems we find were caused by a shortcut someone took earlier.
The plumber checks the meter, existing piping and total appliance load.
You approve the price, and gas piping work is permitted with the City.
Underground runs are marked through DigAlert by calling 811 before any trench is dug.
New piping is installed and held under test pressure to prove it is tight.
After inspection, SoCalGas restores service and appliances are relit and checked.
A real person answers 24 hours a day. You get an honest arrival window and a written price before any work starts.
Leave immediately without touching switches or appliances. From a safe place outside, call SoCalGas at 1-800-427-2200, or 911 if lives may be at risk. Do not go back in until SoCalGas says it is safe. A plumber can then repair the line.
SoCalGas responds to suspected leaks and makes the area safe, and it handles its own meter and supply. Repairs to house piping, connectors and appliance valves on your side of the meter are done by a licensed plumber.
Yes. We size the line for every appliance on the system, pull the permit, mark utilities through 811 before digging, and pressure test the line before it is put in service.
Often, yes. A tankless unit can draw several times the gas of a tank heater. The plumber adds up the full appliance load and checks the line and meter before quoting the conversion.
Salt air near the harbor and ocean corrodes exterior steel gas pipe and fittings faster than inland. Light surface rust can be cleaned and painted. Pitted or flaking pipe, especially at threaded joints, should be replaced before it leaks.
Only if you smell gas, hear gas escaping or see damage. Once the gas is shut off at the meter, SoCalGas has to turn it back on and relight pilots, which can take time after a major quake.
No. Leave it off and have it inspected first. Floodwater can damage the gas control valve and burner. In many cases replacement is the safe choice.
No. SoCalGas says that if you turn off gas at the meter you should leave it off, and that only SoCalGas field employees are allowed to turn on the gas to the meter. Call SoCalGas to restore service.
SoCalGas lists sudden flu-like symptoms, headaches, shortness of breath and fatigue, then dizziness and confusion. A yellow, large or unsteady burner flame is a warning sign. Leave, call 911 if anyone has symptoms, and have the appliance serviced.
If your home has a gas appliance or an attached garage, yes. SoCalGas notes that California requires an approved carbon monoxide alarm for each sleeping area and on every level, replaced at least every three to five years.
This Old House lists a Newport Beach average of $949 for gas line repair. HomeAdvisor's 2025 national figures run from $120 for a simple stove junction leak to $1,500 to $5,000 for buried lines. You get a written price before work starts.
CSST is corrugated stainless steel tubing, often with a yellow jacket. The California Plumbing Code requires it to be bonded with at least 6 AWG copper wire connected to the gas piping, with the jumper no longer than 75 feet to the grounding electrode system.
