How to Tell if You Have a Gas Leak: A Plumber’s Guide

To tell if you have a gas leak, look for signs such as the smell of sulfur or rotten eggs, a hissing sound near a gas line, dead houseplants, and an unusually high gas bill. If you or others feel dizziness, fatigue, or headaches, evacuate the area and call Grand Canyon Home Services immediately.

While natural gas is an efficient and popular energy source in many homes, it can pose risks if there’s a leak. Knowing how to identify a gas leak is crucial for your safety and the safety of your loved ones. 

At Grand Canyon Home Service, we’ve served the West Valley Arizona community for 25+ years, ensuring that every home is safe and free from gas leak dangers. 

As expert plumbers, we’re here to guide you on how to detect a gas leak and what to do next.

Signs of a Gas Leak in Your Home 

Your house may be sending signals of a gas leak, and it’s essential to recognize them:

  1. Distinct Odor: Natural gas has a distinct sulfuric or rotten egg smell, added intentionally to help homeowners detect leaks.
  2. Unusual Sounds: A hissing or whistling sound near gas lines can indicate escaping gas.
  3. Visual Clues: Bubbles in standing water, white or dust clouds near gas lines, or dead houseplants can all indicate a leak.
  4. Skyrocketing Bills: If your gas bill suddenly shoots up without a clear reason, it could be due to a leak.

Physical Symptoms Indicating a Gas Leak 

A decrease in oxygen levels due to a gas leak can lead to various symptoms in both humans and pets:

  • Breathing difficulties, dizziness, and fatigue
  • Irritation in the eyes and throat, headaches, or nosebleeds
  • Mood changes, nausea, or chest pains
  • For pets, watch out for symptoms like disorientation, lethargy, or loss of appetite

Understanding the Risk of Carbon Monoxide Poisoning 

Gas leaks and carbon monoxide poisoning are intrinsically linked, often sharing a dangerous pathway in residential and commercial settings. 

When natural gas, predominantly methane, doesn’t burn off completely in appliances like heaters or stoves, it can lead to the production of carbon monoxide (CO)—a deadly, colorless, and odorless gas. 

While a gas leak itself can present immediate dangers like fires or explosions, it’s the silent and undetected presence of carbon monoxide that poses a prolonged risk to inhabitants.

Both instances underscore the crucial importance of maintaining appliances, ensuring adequate ventilation, and installing detectors in homes to safeguard against these twin threats.

What To Do if You Suspect a Gas Leak

  • Evacuate Immediately: Ensure everyone, including pets, evacuates the house immediately.
  • Open Doors for Ventilation: While leaving, ensure you leave doors open to help dissipate the gas.
  • Call from a Safe Distance: Once outside and safely distanced from your home, call 911. And after notifying them, call Grand Canyon Home Services at 623-777-4779 if you’re in Peoria.
