What actually signals a gas line problem
The clearest sign is the rotten-egg smell near an appliance, a meter or an exterior line. That odor is an additive put into natural gas deliberately, because the gas itself has none — if you can smell it, the system is telling you exactly what it was designed to tell you. A hiss near a fitting, a dead patch of grass over a buried line with no other explanation, or a pilot that will not stay lit through repeated relights all belong in the same category.
The response is the same every time, and it does not vary by how confident you are that it is nothing. Do not flip switches, do not light anything, do not use the garage door opener. Get people and pets out of the house, and call from a safe distance outside. If the smell is strong, the gas utility’s emergency line comes before anything else.
The quieter version of this problem is a system that is not leaking but is undersized. Adding a tankless water heater, a gas range or a pool heater to a line that was sized for the original appliance load produces symptoms that look like appliance faults — low flame, nuisance lockouts, one appliance starving when another fires — and no smell at all.
What Georgetown actually does to this job
Georgetown’s water is the hardest story in this part of the metro. The city blends Lake Georgetown surface water off the North Fork of the San Gabriel with Edwards Aquifer groundwater, and independent testing regularly reports hardness from the high teens into the mid-twenties grains per gallon depending on the blend at the time. Round Rock’s water, already considered hard at roughly fifteen grains, is softer than what a lot of Georgetown households are drinking. This is not a cosmetic problem. At that mineral load, scale accumulates fast enough to shorten a water heater’s service life measurably and to reduce the effective diameter of a horizontal run over time.
Georgetown is split down the middle geologically, and the split follows I-35 closely enough to be useful. West of the highway — Sun City, the San Gabriel bluffs, the Berry Creek side — the ground is Edwards limestone with shallow soil over rock. East of it, toward Weir and the 78626 side, the ground turns to Blackland Prairie clay that swells and shrinks with the season. One city, two entirely different sets of excavation costs and two different reasons a line fails.
Georgetown holds two housing populations that almost nothing else in the metro combines. Sun City Texas, the Del Webb age-restricted community on the northwest side, opened in the mid-1990s and has grown past nine thousand homes — its first-generation sections are now twenty-five to thirty years old, which is precisely the replacement window for water heaters, softeners, supply lines and shutoff valves. Then there is Old Town and the square, one of the best-preserved Victorian courthouse districts in Texas, where houses date to the late 1800s and early 1900s and can still have cast-iron drain stacks and galvanized supply behind the walls, often with a slab addition tacked on decades later.
Sun City’s single-story slab construction and the older Old Town homes reacted to the 2021 freeze very differently — one set lost attic and exterior-wall runs, the other lost brittle old joints that had held for eighty years until they did not.
| Local factor | Why it matters here | What to watch for |
|---|---|---|
| Sun City systems sized for original appliances | Tankless units, outdoor kitchens and larger ranges exceed the original load | Lockouts or flame drop only when two appliances run together |
| Old Town black steel piping | Decades-old steel corrodes at joints and where it passes through masonry | Pre-1950 house; any gas smell near the meter or in a wall |
| Odorant is the designed warning | The rotten-egg smell is an additive; natural gas itself is odorless | Any sulphur smell indoors, at the meter or along a line |
| Limestone west of I-35, clay east | Buried lines work against rock on one side and shifting clay on the other | Dead grass over the line path with no other cause |
| Pressure test is the diagnosis | Isolating and charging the line narrows the failure to one segment | A line-replacement quote issued without a pressure test |
| Permit and inspection | Gas work is inspected for a reason; the record matters at resale | Work offered without a permit |
Georgetown, specifically — what a licensed plumber is looking at
Georgetown’s gas work splits along the same line everything else in this city splits along. In Sun City and the newer west-side subdivisions the systems are relatively young, and the calls are mostly about load rather than leaks — a household adding a tankless water heater, an outdoor kitchen or a larger range to a line that was sized for the original appliance package. Those calls produce no smell at all. What they produce is an appliance that lockouts or drops flame when a second one fires, which reads as an appliance fault and is not one.
Around Old Town and the square the picture is genuinely older. Houses from the late 1800s and early 1900s have usually been converted to gas at some point and then re-converted, and it is not unusual to find original black steel piping that has been in the ground or in the walls for many decades. Steel that old corrodes at joints and at any point where it passes through masonry, and the shallow limestone soil on the west side of I-35 means a buried run may be working against rock rather than sitting in yielding fill. A pressure test is the only honest way to find out which segment is failing before anything is opened up.
How a leak gets located without excavating the whole yard
The tool that does the real work is a pressure test. The line is isolated and charged, and the gauge either holds or it does not. If it drops, the plumber sections the system and repeats the test until the losing segment is narrowed down. That is what turns a vague ‘somewhere out there’ into a specific run, and it is the difference between one excavation and a speculative dig across a yard.
From there a combustible-gas detector and, where the line is buried, a locator confirm the path before a shovel moves. Repairs are then made to the segment that failed, the system is re-tested as a whole, and the work is permitted and inspected — gas work is one of the areas where the inspection is not a formality. On an appliance upgrade, the same visit should include a load calculation against what the existing line and meter can actually deliver, done before the new unit is ordered rather than after it is installed.

Georgetown gas line repair — questions, answered straight
I live in Sun City and my new tankless heater keeps shutting down. Is that a gas problem?
It can be, and it is worth checking before assuming the unit is defective. Tankless heaters draw far more BTUs on demand than the tank they replaced, and a line sized for the original appliance package may not carry the load when something else is running. A licensed plumber can run the load calculation against the existing line and meter and tell you which it is.
My Old Town house still has old steel gas pipe. Should I be worried?
It is worth having inspected rather than worried about in the abstract. Steel that has been in service for many decades corrodes at joints and where it passes through masonry, and Georgetown’s shallow limestone on the west side means a buried run may have been working against rock the whole time. A pressure test tells you whether the system is holding, which is the only answer that means anything.
I smell gas right now — what do I do first?
Leave without flipping switches or lighting anything, take people and pets with you, and call from a safe distance outside. If the smell is strong, call the gas utility’s emergency number first; they will shut the service off. A plumber comes after the immediate hazard is controlled.
Is gas line work ever a DIY job?
No. Gas work carries fire and carbon-monoxide risk, requires a pressure test to verify, and is permitted and inspected for a reason. This is one of the clearest lines between homeowner maintenance and licensed work.
Do I need a bigger gas line for a tankless water heater?
Often, yes. Tankless units draw far more BTUs on demand than a standard tank, and a line sized for the old appliance may not carry the new load. That calculation should happen before the unit is purchased.
What ZIP codes and areas does the Georgetown dispatch line cover?
The dispatch line routes calls across Georgetown and Williamson County, including 78626, 78628 and 78633, to the nearest available independent licensed plumber. If a specific address falls just outside the usual area, the coordinator will say so upfront rather than dispatching someone who cannot actually make it.
