Smell Gas? Do This Right Now
Not every gas smell is an emergency — but you have about 30 seconds to make the right call. Here’s the decision tree, straight from Southwest Gas’s own safety guidance.
🚨 Strong smell, hissing, or you feel unsafe
This is a utility emergency — not a plumber call. Act now.
- Leave immediately. Get everyone out. Leave doors open behind you.
- Don’t touch anything electrical. No light switches, no thermostats, no garage door opener. No phones inside — call from outside.
- Don’t light anything. No matches, lighters, cigarettes. Don’t start or stop any engine.
- From a safe distance, call 911 and Southwest Gas at 877-860-6020 — day or night, customer or not.
📞 911 · 877-860-6020 (Southwest Gas)
🔧 Faint smell, pilot issues, new appliance line
No hissing, no strong odor, everyone’s safe — this is a plumbing job. Call us.
- Don’t try to find the leak yourself. No soapy-water DIY on a live line you can’t isolate.
- Ventilate if safe — open a window on your way out of the room, nothing more.
- Note what you smell and where — near the meter, at an appliance, outdoors by the line.
- Call us. We’ll ask 4 questions, tell you whether to shut the meter valve, and roll a tech with a combustible-gas detector.

Natural gas is odorless — the rotten-egg smell is mercaptan, added by the utility so leaks are detectable. If you smell it strongly, treat it as real until a professional says otherwise. We’d rather roll a false alarm than read about a house that waited.
5 Warning Signs Your Gas Line Needs Attention
Gas leaks don’t always smell. Corrosion, soil shifting, and 30-year-old pipe fail quietly. If any of these match your house, a gas line repair Phoenix AZ inspection costs far less than the alternative.
Rotten-egg smell, even faint
The classic sign. Mercaptan smells like sulfur or rotten eggs — and even a faint, come-and-go whiff near the meter, a gas appliance, or along the line’s path means gas is escaping somewhere. Faint doesn’t mean safe; it means early. This is the one sign that should never wait for “tomorrow.”
▲ Act todayHissing or roaring near piping
A hissing sound from an appliance connection, the meter area, or an exposed line means pressurized gas is escaping fast. This is past the “schedule a visit” stage — if it’s loud or getting louder, treat it as the emergency protocol above: leave, then call 911 and Southwest Gas.
▲ EmergencyDead vegetation in a green yard
A patch of dead or yellowed grass, shrubs, or plants in an otherwise healthy yard — especially in a line between the meter and the house — is a textbook underground leak sign. Escaping gas displaces oxygen in the soil and kills roots. In Phoenix, where every yard is on irrigation, a dead spot that watering doesn’t fix deserves a look.
● Schedule soonGas bill climbing with no change in use
Same appliances, same habits, but the Southwest Gas bill keeps creeping up month over month. A slow leak bleeds therms 24/7 — small enough to never smell, big enough to show up on the bill. Pull 12 months of statements; a steady climb with flat usage is a leak until proven otherwise.
● Schedule soonPilot problems, soot, or lazy flames
Pilot lights that won’t stay lit, yellow or orange flames instead of crisp blue, soot staining around appliance vents, or a furnace that short-cycles. These point to pressure or supply issues in the line — corrosion restricting flow, a failing regulator, or a partial blockage. Your appliances are telling you the line is struggling.
● Schedule soonWhat We Do vs. What Southwest Gas Does
The most common confusion in gas work — and the one that wastes the most weekends. The line is split at the meter, and each side has a different owner. Calling the wrong one first costs you days.
| Issue | Who handles it | What happens |
|---|---|---|
| Strong gas odor anywhere | ✓ Southwest Gas (emergency) | Call 911 + 877-860-6020. Their emergency crews respond 24/7 and shut off gas at the street if needed. No charge for emergency response. |
| Line from street to your meter | ✓ Southwest Gas | The utility owns and maintains everything up to and including the meter. Damage here — call them, not a plumber. |
| Line from meter into your house | ✓ Licensed plumber (us) | Everything past the meter is the homeowner’s property and responsibility — yard lines, appliance connections, regulators, valves. |
| Leak repair on your side | ✓ Licensed plumber (us) | We locate, repair or replace, pressure-test, and permit the work. Southwest Gas won’t touch customer-side piping. |
| New gas line for appliance/pool/outdoor kitchen | ✓ Licensed plumber (us) | We size the line for the appliance’s BTU load, run it to code, pressure-test, and handle the Phoenix permit and inspection. |
| Meter itself damaged or leaking | ✓ Southwest Gas | Don’t touch the meter. Call 877-860-6020 — meter work is utility-only, and tampering with one carries serious penalties. |
| Underground line location before digging | ✓ Arizona 811 (free) | Call 811 at least two working days before any digging — planting, fencing, pool work. They mark utility lines free. Hitting an unmarked gas line is on you. |
The short version: smell gas strong → utility emergency. Need work on your side of the meter → that’s us: (866) 471-4088. When in doubt, call the emergency numbers first — nobody ever got in trouble for being too careful with gas.
Gas Line Services We Provide
Four services, one standard: permitted where required, pressure-tested always, documented in writing. Gas line repair Phoenix AZ homeowners get from us looks boring on paper — and that’s exactly the point.
🔧 Gas Leak Repair
Pinpoint the leak with a combustible-gas detector and pressure isolation — no guessing, no tearing out good pipe. Repair or replace the failed section with code-approved materials, then pressure-test the whole run.
Best for: confirmed or suspected leaks on customer-side piping.
🏗️ New Gas Line Installation
Properly sized new runs for tankless water heaters, pool heaters, outdoor kitchens, fire pits, and gas ranges. We calculate BTU load, size the pipe correctly (undersized lines starve appliances), and run it to code.
Best for: remodels, new appliances, backyard upgrades.
📊 Pressure Testing & Certification
Isolate the system, pressurize with air, and monitor the gauge — the definitive answer to “is my line sound?” Required by inspectors after most gas work, and the smart move before buying an older Phoenix home.
Best for: post-repair verification, real-estate transactions, peace of mind.
🛡️ Shutoff & Safety Valves
Accessible manual shutoff valves at every appliance, plus excess-flow and seismic shutoff valves where they make sense. In a gas event, the fastest shutoff wins — we make sure yours is reachable and working.
Best for: older homes with buried or seized valves, safety upgrades.
Phoenix Gas Codes & Permits — What Applies
Gas work in Phoenix isn’t a handshake deal. Here’s what the rules actually require — and how to spot a contractor who’s skipping them.
Permits are required — and that’s good for you
The City of Phoenix requires a plumbing/gas permit for new gas line installations, line replacements, and most modifications. The permit triggers an inspection — a second set of eyes from the city verifying the work meets code. Any contractor who suggests skipping the permit is asking you to accept uninspected gas work in your walls. We pull the permit, schedule the inspection, and include it in the quote — never as a surprise add-on.
Only licensed contractors touch gas lines
In Arizona, gas piping work falls under the Registrar of Contractors’ plumbing classifications. The handyman exemption that covers minor plumbing does not extend to gas — this is one area where “my neighbor’s guy” isn’t a legal option. Ask for the ROC number and verify it at roc.az.gov before anyone touches your gas line. We’ll give you ours before we arrive.
Materials matter in Phoenix heat
Approved materials for gas piping include black iron pipe, corrugated stainless steel tubing (CSST — the yellow-coated flexible line), and polyethylene for underground runs. What fails here: unprotected steel buried in corrosive desert soil, improper transitions between materials, and DIY flexible appliance connectors used as permanent piping. Phoenix’s soil chemistry and 115°F summers punish shortcuts — we use materials rated for both.
Gas Line Questions, Answered Without the Runaround
The four questions Phoenix homeowners ask us most — answered the way we’d answer them standing at your meter.
How much does gas line repair cost in Phoenix?
A straightforward leak repair on an accessible line typically runs $300–$900 in Phoenix. New gas line installations run $500–$2,000+ depending on length, material, trenching, and permit fees. A standalone pressure test and certification is usually $150–$350. What moves the number: how much line is being replaced, whether it’s underground (trenching adds cost), attic access difficulty, and permit/inspection fees. Be suspicious of flat quotes given sight-unseen — honest gas pricing requires seeing the run.
Is it safe to stay in the house if I smell a faint gas odor?
If the smell is strong, getting stronger, or accompanied by hissing — no. Leave immediately and call 911 + Southwest Gas (877-860-6020) from outside. If it’s faint, intermittent, and you’ve ruled out the obvious (pilot light out, stove left on briefly), ventilate the area, don’t operate any electrical switches or appliances, and call a licensed plumber the same day. Never try to locate the leak source yourself — no soapy-water tests on lines you can’t isolate, no crawling under the house with a flashlight. A faint smell deserves same-day professional attention, not a wait-and-see.
Can I repair a gas line myself in Arizona?
No — don’t. Arizona requires gas piping work to be performed by a properly licensed contractor; the handyman exemption doesn’t cover gas lines. Beyond the legal issue, gas work done wrong doesn’t leak water — it fills a house with an explosive, odorless-until-mercaptan fuel. Improper materials, untested joints, and skipped permits are how houses end up on the news. This is the one trade where DIY isn’t brave, it’s reckless. A licensed pro with a pressure gauge costs a few hundred dollars; the alternative costs everything.
How long do gas lines last in Phoenix homes?
Properly installed black iron or CSST gas lines last 40–75 years — but Phoenix conditions shorten that for older materials. The killers here: galvanized steel buried in corrosive desert soil (20–30 years is optimistic), unprotected joints in contact with concrete or soil, and DIY-era flexible connectors from the 80s–90s that were never meant as permanent piping. If your home still has its original 1970s–80s gas piping, a pressure test every few years is cheap insurance — it takes an hour and tells you exactly where you stand.

What Happens After You Call
Safety triage on the phone
Four questions: what do you smell, where, any hissing, everyone’s safe? If it sounds like an emergency, we tell you to call 911 and Southwest Gas first — no ego about it. If it’s a plumbing-side job, we schedule the visit and tell you exactly what not to touch until we arrive.
🛡️ Safety check: every call starts with “is everyone safe?” — before any scheduling talk.On-site detection with instruments
Combustible-gas detector sweep of the full run, then pressure isolation to confirm which section is losing pressure. We mark the problem area and show you the gauge readings — you see what we see, no black-box diagnosis.
🛡️ Safety check: if we find an active significant leak, gas gets shut off at the meter immediately — repair discussion comes second.One flat price, in writing
Repair vs. partial replacement vs. new run — we lay out the options with a single price for each, explain what the permit and inspection add, and tell you what we’d do if it were our house. You decide. No “sign today” pressure on gas work, ever.
The repair — permitted where required
Failed section replaced with code-approved materials, proper joint compounds and fittings, supports and protection where the line passes through structure or soil. Permit pulled before work starts on jobs that require one; inspection scheduled on completion.
🛡️ Safety check: no open flames near the work area, lines purged per procedure before and after.Pressure test, document, warranty
The whole system gets pressurized with air and the gauge monitored for the full test hold — no drop, no leak, no exceptions. You get the written test result, permit/inspection sign-off where applicable, and our 90-day workmanship warranty. Gas gets turned back on only after the test passes.
🛡️ Safety check: final combustible-gas sweep with appliances running before we leave.Three Recent Gas Line Jobs
Real Valley homes, real numbers — the kind of documented results you’d expect from the most careful gas line repair Phoenix AZ offers. What we found, what we did, and the test results that prove it.
Arcadia — 1962 Ranch, Faint Odor Near the Meter
The problem
Homeowner noticed a faint rotten-egg smell near the gas meter that came and went for two weeks. No hissing, no emergency — but the smell kept returning. Southwest Gas had already checked their side and cleared it: the issue was past the meter.
What we found
Combustible-gas detector flagged elevated readings along the buried yard line. Pressure test on the customer-side piping showed a 4 psi drop over 15 minutes. Excavation revealed 40 feet of original 1962 galvanized steel, corroded through at three separate joints where desert soil had eaten the coating decades ago.
What we did
Replaced the full yard run with polyethylene underground pipe (rated for direct burial, immune to soil corrosion) transitioning to black iron at the house wall. Pressure-tested the entire customer-side system at 15 psi for a full hold — zero drop. Backfilled, compacted, and restored the landscaping.
“Southwest Gas cleared their side and told us to call a plumber. These guys found three separate leaks in the old galvanized and replaced the whole run in a day. The pressure test printout is in our files.”
Ahwatukee Foothills — Pool Heater Starving on Old Line
The problem
New 400,000-BTU pool heater installed by another contractor kept shutting down on high demand. The installer blamed the heater; the heater tech blamed the gas supply. Homeowner was stuck between two companies pointing at each other.
What we found
BTU load calculation told the story in five minutes: the existing ¾-inch line was sized for the old 200K heater plus the house — the new 400K unit needed a full 1¼-inch dedicated run. The line wasn’t leaking; it was starving. Manifold pressure dropped below the heater’s minimum firing threshold every time it called for full heat.
What we did
Ran a new dedicated 1¼-inch CSST line from the meter to the pool equipment pad — 65 feet through the attic and down the exterior wall, properly supported and protected. Phoenix permit pulled, inspection passed. Pressure-tested before the heater was reconnected.
“Two companies argued about whose fault it was. These guys did the math, showed us the BTU numbers, and ran the right size line. Heater hasn’t hiccuped once since.”
North Phoenix — 1985 Two-Story, Remodel Pressure Test Failure
The problem
Homeowner’s kitchen remodel required a gas line modification for the new range location. The city’s rough-in inspection included a pressure test — and the existing 1985 piping failed it, freezing the whole remodel.
What we found
System-wide pressure test dropped 6 psi in 20 minutes. Detector sweep traced the loss to a corroded tee buried in an exterior wall — 40-year-old black iron with no corrosion protection where it passed through stucco and framing. Two more joints in the same wall showed early-stage corrosion.
What we did
Replaced the compromised wall section and both suspect joints with new black iron, properly wrapped and protected at every penetration. Re-ran the full pressure test: held steady for the complete hold period. Signed off, inspection passed, remodel back on schedule.
“The inspector failed our remodel over the old gas line and I panicked. They found the bad joints, replaced them, passed the retest, and our contractor was back to work in two days.”
What Phoenix Homeowners Say After We Test It
“Faint gas smell near the meter for two weeks — scary. They came same-day, found three corroded joints in our 1962 galvanized line, and replaced the whole yard run. Showed us the pressure gauge holding steady before they left. I sleep better now.”
“Our new pool heater kept dying and the installer blamed the heater company. These guys did a BTU calculation on the spot and proved the gas line was undersized. New 1¼-inch run, permit, inspection — heater runs perfectly now.”
“Remodel inspector failed our 1985 gas piping and everything stopped. They traced the leak to a corroded tee in the wall, fixed one joint for $2,200, and told me the rest of my sewer line is fine. They literally talked me OUT of spending more money. That’s when you know.”
