Don't turn on lights or use phones inside. Leave, get to a safe distance, then call ONG at 800-458-4251 to shut off your service. Then call us — we'll find and repair the leak once service is safely off.
What we do with gas lines
Gas plumbing is a specialty within plumbing — it's the same trade but the rules are stricter because the consequences of mistakes are much higher. We hold the licenses required for natural gas and LP work in Oklahoma, carry the insurance for it, and we pull permits when permits are required. Three categories of work make up most of what we do:
Gas line installation and extension
Adding a new gas appliance (range, dryer, fire pit, pool heater, generator) usually means running new line from your meter or from an existing branch. We size the line based on:
- Total BTU demand of the new appliance plus everything else on the system
- Distance from the meter
- Number and severity of bends
- Pressure available at the meter (we measure it)
Undersized gas lines are one of the most common DIY mistakes — the appliance lights but never reaches rated output, or it flames out under load. We size correctly the first time.
Gas line repair and leak detection
Gas leaks have three sources: corroded steel pipe (older homes, especially exterior runs), failed joints (improper installation, age), and damaged flexible connectors at appliances. We detect leaks using electronic combustible gas meters, soap testing, and pressure tests. We repair by replacing the affected section (rarely the whole line) and pressure-testing to verify before we leave.
Pressure testing and inspection
Required after any new install or major repair. We pressurize the system to test pressure (usually 1.5x working pressure), watch the gauge for any drop over a defined period, and document the test for inspection. We also do pressure tests for real estate transactions and for homes that have been winter-vacant.
Common gas line jobs we handle
Range / oven gas line
Adding a gas line to a kitchen for a new range. If you've been cooking on electric and want to switch to gas, this is the conversion. Most kitchens require running line through the wall behind the range from a nearby gas-served appliance (typically the water heater closet or the original gas service).
Cost: $385–$785 depending on routing and distance.
Gas dryer hookup
Replacing an electric dryer with gas. Usually a simpler job than a range because laundry rooms are often near existing gas service. Includes new flex connector, shut-off valve, and pressure test.
Cost: $285–$485.
Outdoor fire pit or grill
Running gas to the back yard for a fire pit, built-in grill, or both. Outdoor runs typically use coated steel or yellow polyethylene buried 18" or deeper, with a riser to bring the connection above ground at the appliance.
Cost: $585–$1,650 depending on distance and whether the meter needs upsizing.
Pool heater
Pool heaters are high-BTU appliances (200,000–400,000 BTU/hr) that often require an upsized supply line from the meter, plus the run to the pool equipment pad. We coordinate with your pool contractor on the connection point.
Cost: $850–$2,200 depending on distance and meter capacity.
Standby generator hookup
Adding gas service to a whole-home standby generator (Generac, Kohler, Briggs & Stratton). Usually paired with the electrician's installation. Generators are continuous-load appliances, so the gas line is sized for sustained demand at maximum output, not just peak.
Cost: $750–$1,850 depending on generator size and distance from meter.
Tankless water heater conversion
Converting from a tank water heater to a tankless almost always requires upsizing the gas supply — tank heaters typically run on 1/2" supply lines, but tankless units need 3/4" or larger to deliver their rated output. This work is usually included in the tankless install quote.
Meter upsizing / utility coordination
If your total gas demand exceeds your current meter's capacity (common when adding a tankless heater plus a pool heater plus a fire pit), we coordinate with ONG to upsize the meter. We do the house-side work, they do the meter swap.
Cost (our side): $185–$485. ONG's meter swap is typically free.
Materials we use
- Black iron pipe — the traditional indoor gas pipe material. Strong, code-approved, recognized everywhere. Used for most indoor runs.
- CSST (corrugated stainless steel tubing) — flexible, much faster to install, requires proper bonding to the electrical grounding system. Excellent for retrofit work where snaking around obstacles matters.
- Coated steel — for outdoor and buried runs that need extra protection from soil corrosion.
- Yellow polyethylene (PE) — for longer buried outdoor runs (to pool heaters, detached garages, fire pits at the back of the yard). Installed with electrofusion fittings or proper transition fittings to steel above grade.
- Flex connectors — for the final connection from rigid pipe to the appliance itself. Always replace these with new on any new install.
Safety — what we will and won't do
We will:
- Pull permits when required by your municipality
- Schedule and coordinate the inspection
- Pressure-test every new install or major repair and document the test
- Bond CSST to your electrical grounding system per code
- Cap and lock-out lines at appliances we disconnect
- Refer you to ONG if the issue is on their side of the meter
We won't:
- Skip permits to save you a fee — the inspection protects you
- Tap into existing lines without verifying they're properly sized for the added load
- Use flexible connectors as a substitute for rigid pipe inside walls
- Leave a job unless the pressure test passes
- Work on systems we don't carry the license for (we'll refer you if needed)
How to know you have a gas problem
Signs of a gas leak
- The distinctive rotten-egg smell (utility companies add this odor specifically so you'll notice)
- A hissing sound near a gas appliance or line
- Dead vegetation in a straight line above a buried gas line
- Unusually high gas bill with no change in usage
- Pilot lights blowing out repeatedly
- Symptoms of CO exposure in residents — headaches, dizziness, nausea — though CO has multiple sources, gas leaks are one
Signs of an undersized gas line
- Furnace and water heater can't both run at full output simultaneously
- Yellow flames at gas burners (should be blue) — incomplete combustion from insufficient gas
- Tankless water heater triggers low-gas-pressure error codes
- Gas fireplace flames much smaller than rated when other gas appliances are running

FAQ — Gas lines in OKC
Leave the house immediately. Do not turn on lights, use phones, or operate any electrical switches — a spark can ignite gas. Once outside and a safe distance away, call ONG at 800-458-4251 and then call us. They'll shut off service at the meter. We'll find and repair the leak once service is safely off.
Costs depend on length, routing, and access. Simple gas line extension for a range or dryer: $285–$685. New gas line for an outdoor fire pit or pool heater: $585–$1,650. Generator hookup with shutoff: $750–$1,850. Full gas line replacement for a tankless conversion: $1,500–$3,500. All work pressure-tested and code-compliant.
In Oklahoma cities, yes — almost all gas line modifications require a permit from your municipality. We pull the permit, do the work, and coordinate inspection. Most homeowners don't realize their handyman or unlicensed installer skipped this step. That can void homeowner's insurance and trigger problems at resale.
In Oklahoma, gas line work generally requires a licensed plumber or licensed mechanical contractor. DIY gas work is both unsafe and often illegal. Even simple-looking jobs involve sizing the line correctly, sealing every joint with the right pipe dope or tape, and pressure-testing the system. Get a licensed plumber.
Three methods, used together: electronic gas detection (handheld combustible gas meters), soap testing at every joint (visible bubbles), and pressure testing (isolate the line and watch the gauge over time). For underground or wall-buried lines, we may use tracer gas with surface detection.
Yes — this is one of our most common gas line jobs. We assess your meter's capacity, size the new line correctly (often requires upsizing the supply), trench and bury the new run, install the connection at the appliance, and pressure-test. Outdoor gas runs use coated steel or polyethylene depending on length and depth.
