Gas line safety and maintenance are crucial for ensuring a secure and efficient home environment. . Natural gas is a highly efficient and cost-effective energy source, powering everything from water heaters and furnaces to stoves and fireplaces. While many homeowners enjoy the benefits of natural gas, it’s important to understand the types of gas lines that run through your home. Knowing more about your gas system can ease any concerns you might have and help you keep your home safe and functional.
At GPS Plumbing, we specialize in gas line maintenance, installation, and repair. In this guide, we’ll walk you through the different types of gas lines commonly found in homes, how to identify them, and what issues you should watch out for.
Where Is Your Gas Meter Located?
The first step in understanding your home’s gas system is knowing where your gas meter is located. Typically, gas meters are found either right next to the house or in an alley behind the property. This meter marks the point where the gas company’s responsibility ends and yours begins. For more information on gas meter safety, visit the Texas Gas Service’s Gas Meter Safety Guide.
The line that runs from the meter to your home can be made of different materials, each with its advantages and potential issues. Let’s take a closer look at these materials and what you should know about them.
Types of Gas Lines: What’s Running Through Your Yard?
- Black Iron Gas Lines
Older homes, particularly those built before the late 1970s, often have black iron or steel gas lines. These sturdy pipes were the standard for many years, but they do have a significant drawback: over time, they are prone to rust and corrosion, especially in the moist Texas soil.- Common Issues:
- Corrosion: As black iron pipes age, they can rust, leading to leaks. These leaks often result in dead patches of grass, a noticeable sulfur smell, and higher gas bills.
- Repair or Replace: When a black iron gas line begins to fail, it’s usually more cost-effective and safer to replace the entire line rather than attempt spot repairs.
- Common Issues:
- Polyethylene (Poly) Gas Lines
Introduced in the late 1970s, polyethylene gas lines are made of durable plastic, making them resistant to the rust and corrosion that plague black iron pipes. These lines are typically installed as continuous lengths, which means fewer joints and, consequently, fewer potential leak points.- Common Issues:
- Physical Damage: Polyethylene lines are more susceptible to damage from excavation or sharp objects like stakes and shovels. While they are resistant to corrosion, they can still develop leaks if the connections at the risers are compromised.
- Ground Movement: Shifting soil can stress the connections at the risers, leading to leaks that require professional attention. Learn more about protecting your gas lines from soil movement at HomeAdvisor’s Guide on Soil Shifting and Gas Lines.

Gas Lines Inside Your Home: Black Iron and CSST
Once the gas line enters your home, it branches off to supply various appliances. The two most common materials used inside the home are black iron piping and Corrugated Stainless Steel Tubing (CSST).
- Black Iron Piping
Most homes built before the last 10-15 years use black iron piping for their internal gas distribution. These pipes are durable and resistant to damage, but the threaded connections can become a weak point over time.- Common Issues:
- Threaded Connection Leaks: Over time, as the pipes expand and contract with temperature changes, the threaded connections can start to leak. If you notice a gas smell indoors, it’s crucial to have these connections inspected by a licensed plumber.
- Common Issues:
- Corrugated Stainless Steel Tubing (CSST)
CSST is a flexible, lightweight piping material that has become popular in newer homes due to its ease of installation. While CSST offers many benefits, including fewer joints and quicker installation, it does require careful handling.- Common Issues:
- Damage from Nails or Screws: CSST is less forgiving than black iron when it comes to physical damage. If a nail or screw punctures the tubing, it can cause a dangerous gas leak. Proper installation with pipe protection is essential to prevent these issues.
- Manifold Systems: CSST is often installed in a manifold system, where a single mainline feeds multiple appliances. This setup reduces the number of potential leak points, but it’s important to ensure the manifold and connections are properly installed and maintained.
