Gas Line Safety in the Highland Lakes

Natural gas and propane are among the most efficient and cost-effective energy sources available to Highland Lakes homeowners, but they require respect and proper handling. Gas line work is one area of home maintenance where the stakes of doing it wrong are genuinely high, a gas leak can cause an explosion, a fire, or carbon monoxide poisoning. This is why Texas requires all gas line work to be performed by a licensed plumber or gas fitter, and why we take every gas line job seriously regardless of its apparent size.

The Highland Lakes region presents some specific gas line considerations. Many homes in the area, particularly in Kingsland, Llano, and rural parts of Burnet County, are served by propane rather than natural gas, because the municipal natural gas distribution network does not extend to all areas. Propane systems have different pressure requirements, different appliance orifice sizes, and different safety considerations than natural gas systems. We are experienced with both natural gas and propane systems and can service either.

The region’s geology also presents some specific challenges for buried gas lines. The limestone substrate that underlies much of the Highland Lakes is highly variable, some areas have deep soil, others have limestone bedrock just inches below the surface. Buried gas lines in rocky terrain are subject to different stresses than lines in deep soil, and the installation techniques need to account for this. We have extensive experience installing and repairing buried gas lines in Highland Lakes conditions.

Common Gas Line Projects in Highland Lakes Homes

Gas Appliance Connections

The most common gas line call we receive is for appliance connections, connecting a new gas range, dryer, water heater, or fireplace to the existing gas supply. While this may seem like a simple task, it involves selecting the correct flexible connector for the appliance, making sure the gas supply line is properly sized for the appliance’s BTU demand, testing for leaks after connection, and verifying that the appliance is operating correctly.

We connect all types of gas appliances, including ranges, cooktops, ovens, dryers, water heaters, tankless water heaters, fireplaces, fire pits, outdoor grills, pool heaters, and generators. For each connection, we use the correct materials and fittings for the application and pressure test the connection before considering the job complete.

Gas Line Extensions and New Runs

Many Highland Lakes homeowners want to extend their gas service to new locations, an outdoor kitchen, a detached workshop, a new addition, or a generator. These projects involve designing the gas line extension to meet the BTU demand of the new appliances, sizing the pipe correctly, installing the line using the appropriate materials (rigid black iron pipe for interior runs, CSST or polyethylene for buried exterior runs), and pressure testing the completed system.

Gas line sizing is a technical calculation that accounts for the BTU demand of all appliances on the line, the length of the run, and the allowable pressure drop. Undersized gas lines cause appliances to underperform, a gas range that does not heat properly, a water heater that cannot keep up with demand. We size gas lines correctly the first time, using the appropriate calculation methods for the specific application.

Gas Leak Detection and Repair

Gas leaks range from minor seeps at fittings to major line failures. We locate gas leaks using a combination of pressure testing, electronic gas detectors, and soapy water testing of fittings and connections. Once the leak is located, we repair it using the appropriate method, tightening a fitting, replacing a section of pipe, or replacing a valve, and pressure test the repaired section before restoring gas service.

If you smell gas or suspect a leak, treat it as an emergency. Leave the building, call your gas utility’s emergency line, and then call us at (325) 248-1800. We provide emergency gas leak response throughout the Highland Lakes.

Outdoor Kitchen and Entertainment Area Gas Lines

Outdoor living is a way of life in the Highland Lakes, and outdoor kitchens, fire pits, and entertainment areas with gas appliances are increasingly popular. We design and install gas line systems for outdoor kitchens, including the underground supply line from the house, the manifold and shutoff valves, and the connections to individual appliances. We can also install dedicated gas lines for pool heaters, spa heaters, and outdoor fire features.

Outdoor gas line installations require careful attention to materials, the supply line must be rated for underground burial, the connections must be weatherproof, and the system must be designed to drain properly to prevent water from entering the line. We use the correct materials and installation methods for outdoor applications and pressure test the completed system before connecting any appliances.

Generator Gas Line Connections

Whole-house standby generators are increasingly popular in the Highland Lakes, where power outages from storms and grid issues can last for days. A standby generator requires a dedicated gas line sized for its BTU demand, typically a much larger line than most homes have available at the generator location. We design and install generator gas lines, including the necessary upgrades to the main gas supply line if required, and coordinate with the generator installer for the final connection.

CSST Gas Lines: What Highland Lakes Homeowners Should Know

Corrugated stainless steel tubing (CSST) is a flexible gas piping system that became widely used in new construction and remodeling from the 1990s onward. CSST is faster to install than rigid black iron pipe and can be routed through walls and around obstacles more easily. It is now the dominant gas piping material in new construction throughout Texas, including the Highland Lakes.

CSST is safe when properly installed and bonded. The bonding requirement, connecting the CSST system to the home’s electrical grounding system, is critical for protection against lightning strikes. A lightning strike near a home can induce a high-voltage surge in the gas piping system, and unbonded CSST can arc and develop pinholes that cause gas leaks. Properly bonded CSST dissipates this surge harmlessly.

Early CSST systems (installed before approximately 2007) were installed under bonding standards that were less stringent than current requirements. If your home has CSST gas lines installed before 2007, we recommend having them inspected to verify that they are properly bonded to current standards. This is a relatively inexpensive inspection that provides significant peace of mind.

Frequently Asked Questions

What should I do if I smell gas?

If you smell gas inside your home, leave immediately without turning any lights or switches on or off. Do not use your phone inside the house. Once outside and away from the building, call your gas utility’s emergency line and then call us at (325) 248-1800. Do not re-enter the building until the gas company has cleared it. A gas leak is a life-safety emergency and must be treated as one.

Can I connect a gas appliance myself?

In Texas, gas line work, including appliance connections, must be performed by a licensed plumber or gas fitter. This is not just a regulatory requirement; it is a safety requirement. Improper gas connections are a leading cause of house fires and carbon monoxide poisoning. Call us to handle any gas appliance connection, from a new range to an outdoor grill.

What is CSST and is it safe?

Corrugated stainless steel tubing (CSST) is a flexible gas piping system that is widely used in new construction and remodeling because it is faster to install than rigid black iron pipe. CSST is safe when properly installed and bonded. However, early CSST systems (installed before approximately 2007) had bonding requirements that were not always followed, creating a potential lightning strike hazard. If your home has CSST gas lines installed before 2007, we recommend having them inspected and properly bonded.

How do I know if I have a gas leak?

The most obvious sign of a gas leak is the smell of gas, natural gas and propane are odorized with mercaptan, which has a distinctive sulfur or rotten egg smell. Other signs include a hissing sound near a gas line or appliance, dead or dying vegetation in a line over a buried gas line, and unexplained increases in your gas bill. If you suspect a gas leak, treat it as an emergency and call us immediately.

Can you run a gas line to my outdoor kitchen or fire pit?

Yes. Outdoor gas line extensions for kitchens, grills, fire pits, and pool heaters are one of our most common gas line projects. We design and install the underground gas line, install the appropriate shutoff valves and connections, and pressure test the system before connecting your appliances.

Do you work with propane systems?

Yes. Many Highland Lakes homes, particularly in rural areas outside of municipal natural gas service, use propane. We install and repair propane gas lines, connect propane appliances, and can advise on propane system sizing and tank placement.

How much does gas line work cost in Marble Falls?

Gas line costs vary depending on the scope of work, a simple appliance connection is much less expensive than running a new gas line across the property. Call us at (325) 248-1800 for an honest assessment and estimate for your specific project.
