Nothing on this page tells you how to fix a gas line, because in Texas that is not a homeowner's job. What it does tell you is how to recognize a leak, what to do in the first two minutes, and what a permitted repair should look like when somebody does it at your house.
If you can smell gas, the first move is to leave, not to look. Gas line repair in Leander is licensed work: Texas counts gas piping as plumbing, so finding and fixing a leak belongs to a licensed plumber, and the city wants a permit and an inspection on the result. Here is how to recognize a leak, what to do in the first two minutes, and what a proper repair looks like.
Natural gas has no smell of its own, so the smell is deliberate. Atmos Energy, which provides natural gas service in Leander, states that federal and state regulations require utilities to odorize natural gas so that it is readily detectable by a person with a normal sense of smell. The U.S. Pipeline and Hazardous Materials Safety Administration names the additive as mercaptan, a harmless non-toxic chemical added for its skunk-like odor.
Your nose is a good detector and a poor sole detector. Atmos Energy's own guidance says continued exposure to the odorant can desensitize your sense of smell, that other odors can mask it, and that in rare cases the odor weakens when gas passes through certain soil conditions. A cold or a lost sense of smell removes the warning entirely. So use the other senses too. PHMSA notes a leak can be heard as an unusual hissing or roaring sound. Outside, look for dirt blowing, bubbling in standing water, or one patch of dead plants in a healthy yard.
PHMSA's instruction for a suspected leak is to leave the area by foot immediately, not to try to locate the source, to direct other people out, and to stay upwind. Call 911 from a safe location, then notify the gas company. What not to do is just as specific: do not operate any pipeline valves yourself, and do not cause an open flame or any other source of ignition such as an electrical switch, a vehicle ignition or a match. The federal public-awareness material is blunter about phones, telling you to call 911 from a neighbor's house rather than from inside.
Atmos Energy says to call 911 and its 24-hour emergency number from a safe distance, that it will send a trained technician immediately to investigate at no cost, and not to assume somebody else will report the leak. That number is on your gas bill. A plumber is the call after that one, never before it.
Leaving costs you nothing if you are wrong. A utility technician arriving and finding nothing is a free visit, by the utility's own account, and that is the trade every single time.
Gas piping is plumbing under Texas law, which is why this is not a handyman job. The Plumbing License Law defines plumbing to include piping used to supply, distribute, circulate or recirculate water, other liquid, or gas. Chapter 1301 of the Occupations Code then states that a person other than a responsible master plumber may not engage in plumbing unless they hold the proper licence, registration or endorsement and their work is supervised and controlled by someone licensed under the chapter, and that anyone who advertises or offers to perform plumbing must secure the services of a responsible master plumber.
That designation carries things a homeowner can check. The Texas State Board of Plumbing Examiners requires a Responsible Master Plumber to carry at least $300,000 of general commercial liability insurance, to obtain all necessary permits and request all inspections the plumbing or building codes require, to ensure everyone performing the work holds a current licence, and to display the company name and the RMP licence number on service vehicles. Our licence is RMP 15304, and the way to confirm it, or anybody else's, is in our guide to checking a Texas plumbing licence. Propane is a separate licence: the plumbing board's own course material says installing liquefied petroleum gas piping requires a licence from the Texas Railroad Commission first.
The inspection is the part that protects you, and the part an unpermitted repair skips. Leander has adopted the 2021 International Fuel Gas Code, which requires every piping installation to be visually inspected and pressure tested before acceptance and initial operation. The City of Leander says a permit is required before starting any construction on property inside the city limits, lists plumbing remodels among permitted activities, and notes the list is not comprehensive and should be confirmed with a city building inspector.
| What the code requires | What that means at your house |
|---|---|
| Visual inspection and a pressure test before the system is accepted | The repair is proved, not assumed |
| Test pressure at least one and a half times working pressure, never below 3 psig | The test is harder than normal service |
| At least 10 minutes of held test on a single-family system | A slow loss has time to show itself |
| Joints and welds left exposed during the test | Nothing is buried before it is checked |
| Pressure read on a manometer or calibrated gauge, source isolated | An instrument, not a judgement |
| Underground piping at least 12 inches below grade | Depth that survives a shovel or a mower |
Two details tell you what you are looking at. The code requires exposed gas piping other than steel and corrugated stainless steel tubing to be labeled yellow and marked Gas in black letters at intervals no greater than 5 feet. And where any part of the system is corrugated stainless steel tubing, it must be electrically continuous and bonded to the electrical service grounding electrode system, or to the lightning protection grounding system where one exists. That bonding matters here, where lightning is not rare. Our gas leak detection and repair work is done to that code and inspected on it.
Call 811 before a fence post, a tree or a pool, because in Texas it is the law rather than a courtesy. Texas811, the state's notification center, says homeowners should contact 811 for building or repairing a fence, planting a tree, installing a sprinkler system or any chore that requires digging, even when the work is in your own backyard. A person who intends to excavate must notify a notification center no earlier than the 14th day before the work starts and no later than the 48th hour before it starts, excluding weekends and legal holidays. Excavate means using explosives or powered equipment, including auguring, boring, digging, drilling, grading, ripping, scraping or trenching, to disturb soil to a depth of 16 or more inches. Skipping the notice makes an excavator liable for a civil penalty of not less than $500 or more than $1,000.
Then there is the part people get wrong. The law exempts an underground facility that serves only its owner or the owner's tenant and sits solely on the owner's property. The marking service locates the utility's line to your meter; the private run from the meter out to a pool heater, a grill or a casita is yours, it is not in that system, and nobody is coming to paint it on your grass. If a yard line was added after the house was built, the plumber who works on it is the one who should locate it.
Not every gas problem announces itself with a smell, and carbon monoxide is the one that does not. The U.S. Consumer Product Safety Commission reports that on average more than 200 people in the United States die every year from carbon monoxide produced by non-automotive consumer products, a category that includes malfunctioning furnaces, ranges, water heaters and room heaters. The symptoms read as flu without the fever: headache, fatigue, shortness of breath, nausea and dizziness. CPSC states that most people have no symptoms from prolonged exposure at roughly 1 to 70 ppm, that symptoms become noticeable above 70 ppm, and that at sustained levels above 150 to 200 ppm disorientation, unconsciousness and death are possible.
CPSC's prevention advice is to have the heating system professionally inspected and serviced annually, with the inspector checking chimneys and flues for blockages, corrosion, partial and complete disconnections and loose connections, and to install alarms meeting the current UL 2034 standard on every level and outside sleeping areas. It then says the thing that matters most: an alarm adds protection but is no substitute for proper use and upkeep of the appliances. Its instruction on servicing is the same as this whole page, never service fuel-burning appliances without the proper knowledge, skill and tools.
When the emergency part is over, what is left is a licensed, permitted, tested repair, and that is the job for houses in Leander and across our Leander service area. The office is open Monday to Friday 8:00 to 5:30 and Saturday by appointment, under licence RMP 15304.
Leave, and do it before you do anything else. The federal Pipeline and Hazardous Materials Safety Administration's instruction is to leave the area by foot immediately, not to try to locate the source of the odor, to direct other people out as well, and to stay upwind. Then call 911 from a safe location and notify the gas company. Do not cause any open flame or other potential source of ignition such as an electrical switch, a vehicle ignition or a match, and do not start motor vehicles or electrical equipment. Natural gas service in Leander is provided by Atmos Energy, whose own guidance is to call 911 and its 24-hour emergency number from a safe distance, and not to assume somebody else has already reported it.
No. Texas defines plumbing to include piping used to supply, distribute, circulate or recirculate water, other liquid, or gas, and the Plumbing License Law says a person other than a responsible master plumber may not engage in plumbing unless they hold the proper licence, registration or endorsement and their work is supervised and controlled by someone licensed under the chapter. The same law says anyone who advertises or offers to perform plumbing must secure the services of a responsible master plumber. Propane is a separate matter again: the Texas State Board of Plumbing Examiners' own course material states that installing liquefied petroleum gas piping requires a separate licence from the Texas Railroad Commission.
Yes, and the inspection is the point of it. The City of Leander says a permit is required before starting any construction located on property within the city limits, lists remodels involving plumbing among the activities requiring permits, and notes that the list is not comprehensive and should be confirmed with a city building inspector. Leander has adopted the 2021 International Fuel Gas Code, which requires that all piping installations be visually inspected and pressure tested before acceptance and initial operation. Obtaining permits and requesting inspections is part of what a Responsible Master Plumber designation obliges a plumber to do.
Not on its own. Utilities are required by federal and state regulation to odorize natural gas so that it is readily detectable by a person with a normal sense of smell, and mercaptan, the additive, has the skunk-like smell people describe as rotten eggs. Atmos Energy's own guidance is clear about the limits: continued exposure to the odorant can desensitize your sense of smell, other odors in the area can mask it, and in rare cases the odor can be weakened when gas passes through certain soil conditions. Use hearing and sight as well. A hissing or roaring sound, dirt blowing, bubbling water or dead plants in one patch are all signs.
