S.W.A.T. Plumbing LLC helps homeowners understand common gas line issues found in older homes and provides safe, code-compliant repairs. Their licensed plumbers use advanced tools to locate leaks, replace aging pipes, and ensure each system delivers reliable, safe gas service.

Gas lines age just like any other part of a home’s plumbing system. Older homes often have outdated materials, worn joints, or hidden corrosion that may go unnoticed for years. Because gas lines carry fuel to appliances, even small problems can become dangerous if ignored. This guide explains the most common gas line issues in older homes and when it’s time to call a professional.

Aging or Corroded Gas Pipes

Many older homes were built with black steel gas lines. While this material is durable, it corrodes over time—especially in humid or damp conditions. Corrosion wears the inside and outside of the pipe, eventually creating thin spots or tiny holes that allow gas to escape.

Signs of corrosion include:

Rust flakes on the pipe
Foul or metallic smells around gas appliances
Discoloration or pitting on the pipe surface

Corroded pipes should be replaced immediately. Homeowners can learn more about how aging plumbing materials break down on S.W.A.T. Plumbing’s gas line repair page.

Outdated Pipe Materials and Fittings

Older homes sometimes contain gas lines made from outdated or unsafe materials. Black steel is still common, but older systems may also include:

Copper gas lines (discouraged due to corrosion and code limits)
Old flexible connectors that can crack or kink
Threaded fittings that no longer seal tightly

Over time, fittings become loose due to vibration, temperature shifts, or natural settling of the home. Even a minor gap in a joint can release gas.

A licensed plumber can inspect the system, replace outdated connectors, and install safer modern materials.

Gas Leaks Hidden Behind Walls or Under Floors

Small gas leaks often develop slowly and remain hidden behind walls, under floors, or inside crawlspaces. Because gas dissipates quickly, homeowners may not notice the smell unless the leak becomes significant.

Common signs include:

A faint “rotten egg” odor near appliances
Higher-than-normal gas bills
Hissing sounds near the line
Houseplants that wilt or die unexpectedly

Gas leaks are extremely dangerous and should only be handled by licensed professionals. S.W.A.T. Plumbing uses advanced detection equipment that finds leaks without opening large areas of the home.

For broader safety guidance, the EPA Indoor Air Quality Program provides helpful information on harmful indoor gases.

Damage Caused by Ground Movement and Soil Shifts

Homes in Aledo and Fort Worth often sit on clay soil that expands and contracts with seasonal moisture. Over decades, this movement can place stress on buried gas lines, causing cracks, joint failures, or weakened fittings.

Signs of soil-related gas line issues include:

Gas smell near the yard or foundation
Dead or discolored grass above buried lines
Bubbles in puddles or wet soil after rain

Underground leaks are hard to detect without professional tools. S.W.A.T. Plumbing explains related underground concerns on their Slab Leak Repair page, which describes how shifting soil affects plumbing systems.

Old or Failing Appliance Connectors

Flexible appliance connectors deliver gas to stoves, dryers, and water heaters. Older connectors—especially those installed more than 20 years ago—can crack, break, or loosen.

Warning signs include:

A noticeable gas smell when appliances start
Fluctuations in flame size
Burners that light unevenly
Whistling sounds near the connector

Replacing these connectors with modern, code-approved materials keeps appliances safe and reduces leak risk.

Improper DIY Repairs From Previous Homeowners

Older homes often have a long repair history. Some past owners may have attempted DIY gas line fixes or installations that do not meet safety codes. Common mistakes include:

Using incompatible materials
Poorly sealed threads
Unsupported pipes that sag or twist
Joints overtightened to the point of weakening

These issues can remain hidden for years until they cause sudden leaks or appliance failures. A licensed plumber should inspect older systems for any unsafe modifications.

When to Call a Plumber for Gas Line Problems

Gas line issues require immediate attention. Homeowners should call a licensed plumber if they notice:

The smell of gas anywhere inside or outside the home
Hissing near pipes or fittings
Dead patches of grass above underground lines
Unexplained dizziness, headaches, or fatigue indoors
Pilot lights that go out repeatedly

If a strong gas smell is present, homeowners should leave the home immediately and call emergency services before contacting a plumber.

Once the area is safe, a licensed professional can locate the leak, replace damaged sections, and bring the system up to current code requirements.
