Gas ranges and cooktops
Switching from electric to gas, or moving the range in a kitchen remodel, usually means a new branch line through the wall or floor, ending at a shutoff valve and a new connector.

Quick answer
If you smell gas, get everyone out and call SoCalGas from a safe place outside, or 911 if anyone could be hurt. Once SoCalGas has made it safe, a licensed plumber repairs the pipe or fitting on your side of the meter. New gas lines need a City of Covina permit, and water heater gas hookups must meet Handout #12. Call (626) 746-1970.

What to do if you smell gas in Covina
Leave the area first, then call SoCalGas at 1-800-427-2200 from a safe place; call 911 if anyone could be hurt or you cannot reach SoCalGas.
Get everyone out
People and pets leave the house, apartment or shop. Do not stay inside to hunt for the source.
Move well away
Go to the sidewalk, a neighbor's yard or down the block. In an apartment complex, move away from the building and any bank of gas meters.
Call SoCalGas
From outside, call SoCalGas at 1-800-427-2200. SoCalGas is the gas utility for Covina and responds to suspected leaks.
Call 911 if there is danger
If there is fire, a strong smell spreading outdoors, a line hit by a car or a shovel, or anyone feels ill, call 911. A downed power line is also a 911 call.
Call us for the repair
Once SoCalGas has checked the situation and made it safe, the repair on your side of the meter is a plumbing job. Call (626) 746-1970 and we send a licensed plumber to find and fix the leak.
Those outside numbers are plain text on purpose. Save the SoCalGas number in your phone now, so you can call it from the curb without searching. If you also have a burst pipe or a sewage backup, our 24/7 emergency plumber page covers what to do first.
Who handles which part of the gas system in Covina
SoCalGas handles emergencies, the meter and its own lines; a licensed plumber handles the gas piping and appliance connections on the property side of the meter.
| Situation | Call first | Then |
|---|---|---|
| Smell of gas inside or outside | SoCalGas, 1-800-427-2200, from a safe place | Plumber for the repair once it is safe |
| Fire, injury or major damage | 911 | SoCalGas, then a plumber |
| Gas line hit while digging | Leave, then call 911 and SoCalGas | Plumber for the property-side piping |
| Leak at a range, dryer or water heater connector | SoCalGas if you smell gas | Plumber to replace the connector or valve |
| New line for an appliance, fire pit or barbecue | Plumber | City permit and inspection |
| Old or corroded gas piping through the house | Plumber | City permit, piping replaced and tested |
Gas is separate from water and sewer. Covina has six water suppliers, and the name on your water bill tells you which one serves you. City of Covina Public Works handles the local sewer mains, while the property owner maintains the sewer lateral. Our who to call for water, sewer and gas guide sorts out every agency in one place.
Gas leak repair on your side of the meter
Most home gas leaks we repair are at appliance connectors, shutoff valves and threaded fittings, with fewer inside walls or underground.
On a gas leak call, the plumber checks the piping and fittings from the meter to each appliance. Leaks are confirmed with leak detection solution or an electronic detector, and the system can be pressure tested to show whether any part is losing gas. The repair is priced in writing before work starts.
| Where the leak is | Published range | What the repair usually involves |
|---|---|---|
| At the junction behind a stove | $120 to $250 | New connector, fitting or appliance shutoff valve |
| Hidden in walls or crawl spaces | $270 to $760 | Opening access, replacing a section of pipe or fittings |
| Buried line | Adds $1,500 to $5,000 | Digging, replacing the buried run, testing |
These are published estimates, not our prices. Call (626) 746-1970 for an exact quote on your gas leak repair.
Why older Covina homes have gas piping trouble
About two-thirds of Covina's homes were built before 1970, according to the City's 6th cycle Housing Element, certified in March 2024. City code enforcement staff estimate about 30% of homes need some repair. In houses this age, the gas piping is often original, and the connectors behind ranges and dryers have been bent, moved and reconnected through several appliances. Old connectors and valves that will not turn are the usual weak points. When we see one, we point it out and price the replacement separately so you can decide.
Older houses, including those on the oldest blocks around downtown Covina, may also have had additions or remodels over the decades. When a gas line was extended for a new room or appliance without checking its size, it can show up later as a weak flame or a water heater that struggles when the dryer runs.
Handout #12: the gas shutoff, flex connector and sediment trap at your water heater
City of Covina Handout #12 requires an AGA-approved gas shutoff valve, flex connector and sediment trap on every water heater, along with a permit for every replacement.
Handout #12 took effect January 1, 2026, and is based on the 2025 California Plumbing Code. It is the City's checklist for residential water heaters, and the gas hookup is one of the first things an inspector looks at. Most of the competitor pages we have read never mention it.
| Item | What the handout says | Why it matters |
|---|---|---|
| Gas shutoff valve | AGA-approved shutoff valve at the heater | Lets you or a plumber turn off gas to the heater alone |
| Flex connector | AGA-approved flexible connector | Replaces old rigid or worn connectors that crack or leak |
| Sediment trap | On the gas supply at the control valve: a T fitting with a nipple at least 3 inches long and a cap (CPC 1212.9) | Catches debris before it reaches the gas valve |
| Bonding | Metallic piping bonded with #8 copper wire and clamps, tying the cold, hot and gas lines together at the heater | Keeps the metal piping at the same electrical potential |
| Controls height | Pilot and controls at least 18 inches above the floor where there is an open flame; 18-inch stand in garages | Keeps ignition sources above floor-level vapors |
| Venting | Type B double wall vent in concealed spaces; vent ends at least 12 inches above the roof | Carries combustion gases outside |
| Permit | Required for every replacement, issued to a C-36 plumbing contractor or an approved homeowner-builder | The City inspects the hookup before it is signed off |
The same handout covers two seismic straps, the relief valve drain, the drain pan and combustion air. Our water heater repair and replacement page walks through all of it. If you are moving to tankless, the gas line usually changes too, and our tankless water heater page explains why.
New gas lines for ranges, dryers, water heaters and backyard features
A new gas line runs from existing piping to the new appliance, sized for the total load, with a shutoff at the appliance and a City permit and inspection.
Gas dryers
Many Covina garages and laundry rooms have a gas stub that was capped years ago. We test it and reuse it if it is sound, or run a new line if it is not.
Water heaters
A new tank or tankless heater may need a different line size. Tankless units often need far more gas than the old tank. Hookups follow Handout #12.
Fire pits and barbecues
Backyard fire features and built-in grills need a buried or protected line from the house. Any trench starts with an 811 call.
Sizing comes first
Every gas appliance has a rated demand. Before adding one, the plumber adds up the demand of what is already connected, measures the run and confirms the existing pipe can carry the new load. If it cannot, the fix may be a larger line from the meter or a separate branch. A line that is too small can starve appliances when several run at once, such as a tankless heater, a range and a dryer on a Saturday morning.
Published cost ranges for new gas lines
HomeAdvisor's 2025 national range for installing a gas line is $272 to $936 per line. It lists new gas line work at $15 to $30 per linear foot, trenching at $5 to $12 per foot, and permits at $100 to $300. Covina permit fees are posted at the Building & Safety counter. Long outdoor runs, larger pipe and wall or patio openings can push a job outside the range. These are published estimates, not quotes. Call (626) 746-1970 for an exact quote on your new gas line.
Covina permits for gas line work
Gas piping work in Covina needs a City plumbing permit pulled in person at Building & Safety, and Handout #14 says no work may be concealed before inspection approval.
Fuel gas piping is covered by Chapter 12 of the California Plumbing Code, and City Handout #14 says a permit is required to install, alter, repair, replace or remodel plumbing systems. Gas work falls under that. Handout #12 adds that every water heater replacement needs a permit, issued only to a C-36 plumbing contractor or an approved homeowner-builder.
Building & Safety is at 125 E College St, phone 626-384-5460, open Monday to Thursday, 7 a.m. to 6 p.m., closed 1 to 2 p.m. There is no online permit portal; most permits are issued over the counter while you wait. Inspections are requested by email, with the permit number, address, inspection code and type.
Written scope and price
The plumber lists the appliances, the pipe route, the pipe size and whether walls, floors or a trench will be opened.
Permit at the counter
The permit is pulled at City Hall before the work starts, usually the same day.
Install and pressure test
New piping is installed and pressure tested to show it holds without loss.
City inspection
The inspector checks the piping while it is visible, including any trench before backfill. Nothing is covered first.
Connect and light
After approval, appliances are connected, checked for leaks and put into service.
Homes in unincorporated Charter Oak follow County rules, not City of Covina permits. Our Covina plumbing permits guide covers the City counter, Handouts #12 and #14 and the email inspection process.
Call 811 before digging a gas line trench
California law requires a call to 811 at least two working days before you dig, not counting the day you call, so buried utilities can be marked for free.
Southern California Edison's 811 guidance says to call at least two working days before excavation, excluding the day of the call, and that locating is free through 811 or DigAlert. Pre-mark the dig area in white paint, flags or chalk so locators know where to look. Edison also says to use hand tools within 18 to 24 inches of the outside edge of a marked underground line.
- Plan the trench route from the house to the patio, fire pit or grill
- Mark the route in white
- Call 811 at least two working days ahead
- Wait for the marks before digging
- Hand dig near any marked line
811 marks public utility lines, not your sprinkler pipe or your sewer lateral. Covina backyards often have both, and the City says the lateral, from the house to the public main, is the owner's to maintain. If it is in the way, our sewer lateral camera and repair page explains how we locate it by camera before digging.
Earthquake gas shutoff valves in Covina
The California Plumbing Code requires earthquake-actuated gas shutoff valves where a local ordinance requires them, and we have not confirmed a City of Covina ordinance that does.
An earthquake-actuated, or seismic, gas shutoff valve closes on its own when it senses strong shaking. California Plumbing Code section 1211.8 says these valves are provided where a local ordinance requires them, and that they must be certified by the State Architect. Where an ordinance is silent, installation follows the manufacturer's instructions.
We have not found a Covina rule requiring one, but that does not rule out a requirement for your project. If you are planning a remodel, a gas repipe or a sale, ask Building & Safety at 626-384-5460. Some owners install one anyway. If you want one, we can price a certified valve at the meter in your written estimate.
Gas work in rentals, apartments and businesses
Gas work in Covina rentals and businesses usually means more meters, more appliances and more people to schedule around.
Census figures for 2019 to 2023 put owner-occupied housing at 57.3%, so a large share of Covina homes are rented. Multi-unit buildings often have a bank of gas meters and long runs to each unit's range and water heater. When one unit has a leak, the plumber may need access to the meter area and to neighboring units, so owners should plan tenant notice. Restaurants and shops downtown depend on gas for cooking lines and water heaters, and our commercial plumbing page covers how we schedule gas work around business hours.
Work is done by independent CSLB-licensed C-36 plumbing contractors. Before anyone touches your gas piping, ask for the license number and check it with our license check guide.

Questions Covina homeowners ask
What should I do if I smell gas in my house?
Leave the house right away and call SoCalGas at 1-800-427-2200 from a safe place outside. Call 911 if anyone is in danger or you cannot reach SoCalGas. Do not stay inside to look for the leak. Once it is safe, call (626) 746-1970 for the repair.
Does a plumber fix gas leaks in Covina?
Yes. A licensed plumber repairs gas piping, fittings, valves and appliance connectors on your side of the meter. SoCalGas handles emergencies and its own meter and lines. Call SoCalGas first if you smell gas, then a plumber for the repair.
Do I need a permit to run a gas line in Covina?
Yes. City Handout #14 says a permit is required to install, alter, repair or replace plumbing systems, and gas piping is covered by the California Plumbing Code. Permits are pulled in person at 125 E College St, and work is inspected before it is covered.
What does Covina require for the gas line on a water heater?
Handout #12, effective January 1, 2026, requires an AGA-approved gas shutoff valve, flex connector and sediment trap. The trap is a T fitting with a capped nipple at least 3 inches long. The handout also requires bonding the gas, hot and cold lines with #8 copper wire.
How much does it cost to run a gas line for a stove or dryer?
HomeAdvisor's 2025 national range is $272 to $936 per new gas line. Distance, pipe size and wall access change the price. That is a published range, not a quote. Call (626) 746-1970 for an exact quote.
Do I need to call 811 before digging a gas line trench?
Yes. California law requires calling 811 at least two working days before digging, not counting the day you call. Marking is free. Pre-mark the area in white, and remember 811 does not mark sprinkler lines or your sewer lateral.
Is an earthquake gas shutoff valve required in Covina?
We have not confirmed a Covina ordinance requiring one. The California Plumbing Code requires these valves where a local ordinance does, and they must be State Architect certified. Ask Building & Safety about your project, or ask us to price one.
Do tankless water heaters need a bigger gas line?
Often, yes. Tankless heaters usually need more gas than the tank they replace, so the existing line may be too small. The plumber checks the total load and the pipe length first. See our tankless page.
