Recognizing the Signs of a Potential Gas Leak

At Leichhardt Plumbing, we stress the importance of rapid gas leak detection to mitigate potential hazards effectively. Gas leaks can lead to dangerous situations if undetected, so we want to equip homeowners with the knowledge to recognise common signs of a possible issue.

Unusual Smells

A primary indicator of a gas leak is the presence of an unusual odour, often described as a rotten egg smell, indicating the release of gas. Most gas companies add a sulphur-like odorant, which emits a rotten egg smell, to aid in easier leak detection. If you notice such a smell near gas appliances or pipes, that is a major red flag that should not be ignored.

Hissing Noises

If you smell gas in your home, be alert for hissing, whistling, or roaring sounds from gas lines or appliances, which could indicate a leak. Detecting a gas leak in your home is a clear sign of escaping gas that demands further investigation. The disturbance might be faint, so ensure a thorough examination near your stove elements and pipeline junctions.

Visible Signs

Stay alert for signs of gas leaks such as dust clouds, mist, or bubbles in still water, which can denote compromised gas lines. Leaks can occur when dirt is blown around or when water bubbles, suggesting an urgent gas escape.


The added sulphuric scent acts as a safety alert for gas leaks, allowing for preemptive action to protect your property. Because natural gas is odourless, producers add a distinct scent to make leaks more detectable.

If you suspect a leak, avoid ignition sources, shut off the main gas supply, and contact a professional immediately due to the significant danger posed by gas leaks.


Listen attentively for sounds like hissing, whistling, or roaring from gas appliances or pipes, which may signal a leak. This noise indicates combustible gas escaping at high pressure and suggests a gas leak can be present. The sound may be subtle, so take time to methodically check all your gas appliances. Focus on locations where different components join, like behind the stove or at pipe joints.

If you hear unusual sounds, these signs gas leak should prompt you to avoid ignition sources, leave the area, shut off the main gas valve, and call Leichhardt Plumbing immediately on 1300 349 338.


Signs of a gas leak may include visible dense white mist or dust clouds coming from gas line breaches. Upon identifying visible evidence of a gas leak, steer clear of ignition sources, vacate the area, and contact Leichhardt Plumbing for emergency assistance.

This scenario, where there gas leak is strongly indicated, suggests gas rapidly escaping at high pressure. Also, look out for bubbles rising in any standing water around your home, a tell-tale sign of gas seeping out underground. Dead vegetation in a distinct line along a gas pipeline may also be a warning sign.

Physical Symptoms

Exposure to a gas leak your home can cause various physical symptoms, including headaches, dizziness, fatigue, nausea, and eye or skin irritation. If you or other occupants experience any persistent symptoms, exit the vicinity as soon as possible to ensure your safety and seek medical attention should the need arise.

These effects may indicate risks to your health due to unsafe gas levels, carbon monoxide poisoning, or oxygen deprivation. Having a licensed gas fitter like Leichhardt Plumbing evaluate the situation is crucial.

Gas Usage and Bills

A sudden increase in your gas bill could signal an undetected gas leak. Compare your current bills to the same period last year to identify any concerning changes. Higher than average gas usage often means gas is escaping through leaks.

If you spot a spike in your gas bills potentially suggesting gas leakage, schedule Leichhardt Plumbing’s gas leak detection service by calling 1300 349 338.

Testing for Gas Leaks

Consider obtaining leak detectors, which are crafted to pinpoint gas leaks. These handy units can help detect gas leak situations that the detectors are cautioning you about. Be sure to select quality models approved for residential use.

Another uncomplicated manoeuvre is to perform the soapy water procedure, a mainstay in gas detection tactics. Concentrate on regions emitting a distinct egg smell, as this is indicative of a leak.

Mix a couple tablespoons of liquid dish or hand soap into a spray bottle filled with water. Particularly when gas is a concern, employ your detection techniques on piping joints, valves, appliance connections, and convergence points of different components.

The cobalt blue dye added specifically to indicate any gas escaping LPG mixtures can also assist in highlighting possible leaks. Escaping gas propane will leave a visible blue stain.

If flames in your kitchen burner burn more orange than blue or frequently extinguish, it could point to an airflow issue from a potential leak.

In a gas emergency, trust your nose as well to detect any unusual scents indicating gas out your usual environment.

Move cautiously around your appliances, meter box, and in-home piping system, keeping your nose close to the ground for subtle hints of gas wafting through.

If there’s ever any indication of a leak, you should immediately evacuate the area and call professional help from Leichhardt Plumbing. Our licenced gas fitters have professional-grade leak detection equipment and can provide help right away to accurately identify the leak location. We can then fix gas pipes or fittings and ensure the safety of your home.

Gas Detectors

Gas detectors are essential devices specifically calibrated to identify gas leaks, ensuring enhanced detection capabilities.

Choose detectors that comply with Australian Standards for reliable protection.

Ideally, install a gas detector in every sleeping area, especially near hot water systems and in rooms where gas appliances are used. Leichhardt Plumbing can advise on the number of detectors needed for your home layout and install them professionally. We recommend hardwired, plug-in and battery-powered units with a built-in alarm that activates if unsafe gas levels are reached.

This gives occupants an early warning to evacuate and call emergency services.

Gas detectors offer continuous surveillance to prevent gas leaks your home might be susceptible to in your home and should undergo monthly testing. Replace detector batteries every 6 months or as per manufacturer guidelines to ensure continued protection. You’ll want to respond swiftly and never disregard signals from your detector that hint at a possible gas escape.

If the alarm sounds, evacuate immediately and call Leichhardt Plumbing to identify and repair the leak source.

Flame Observation

Observing deviations in your stove’s pilot lights and burner flames can reveal underlying airflow problems, hinting at leaks. However, if you need to do gas leak checks, we caution homeowners to call a licensed gas plumber rather than conduct tests themselves due to fire and explosion risks from leaking gas. Instead, contact licenced professionals like Leichhardt Plumbing to perform detailed leak checks using detection equipment. We have the proper tools and training to accurately pinpoint any leaks and restore proper burner performance.

Soapy Water Test

Before calling a professional, try the soapy water test on gas pipes to check for leaks, creating a solution from household dish soap and water. Mix a few tablespoons of liquid dish soap with water in a spray bottle as part of the soapy water test for gas leaks. Spray or brush soapy water onto gas pipes, joints, valves and appliance connections to check for areas where gas leaks can occur around your appliances. Any bubbles forming where a gas leak can occur indicate gas is escaping and signify a leak that should be addressed immediately.

Check those areas closely for bubbles.

Our licensed technicians employ cutting-edge equipment for precise gas leak location and resolution services.

And remember, if suspicion arises, it’s crucial to leak turn off your gas at the main valve before contacting professionals. Escaping gas tends to accumulate in these lower, enclosed areas.

If You Suspect a Gas Leak

Should you suspect a gas leak, take the following immediate safety steps:

  1. Avoid using phones, turning on/off lights, ignition sources, or electrical equipment in the area, as these could spark an explosion.
  2. Evacuate everyone from the home and leave doors/windows open on your way out for ventilation.
  3. From a secure distance, dial 000 to inform emergency services of the problem after you’ve turned off the gas.
  4. Also, promptly contact Leichhardt Plumbing at 1300 349 338 to dispatch our licensed gas technicians immediately.
  5. Do not re-enter the home yourself to investigate or attempt to fix the issue.
  6. Shut off the gas main valve outside if safely possible, otherwise wait for firefighter assistance.
  7. Wait for first responders and our technicians to deem the area safe before returning inside.

Gas leaks always require urgent response. So if you notice concerning signs or suspect any kind of leak, put safety first by acting promptly and leveraging Leichhardt Plumbing’s professional assistance.

Safety Precautions

Prioritise safety when responding to a suspected gas leak situation. Take the following precautions to prevent accidents:

  • Do not use any phones, turn lights on/off, or activate electrical equipment in the area, as these could generate sparks.
  • Immediately evacuate the building and leave doors/windows open for ventilation.
  • Shut off all your gas mains if they are easily accessible, then immediately proceed to a safe location upwind from the leak.
  • Do not re-enter the home or attempt to investigate the source yourself.
  • From a secure location, call 000 to alert emergency responders.
  • Also, without delay, call your dedicated team at Leichhardt Plumbing on 1300 349 338 so our licensed gas technicians can be dispatched.
  • Keep the number for emergency services and Leichhardt Plumbing readily available.
  • Wait for first responders and technicians to evaluate the premises and deem it safe before going back inside.

In the event gas suspicions arise, evacuate forthwith and connect with proficient helpers. Never take risks by attempting to identify or mitigate the issue on your own.


If you suspect a gas leak in your home, evacuation should be your top priority. Leave doors and windows open as you exit if it is safe to ventilate the home.

Make sure all occupants safely exit the building immediately and do not use gas appliances or switches. Do not stop to collect belongings or investigate the leak source.

Ensure your family and pets are guided to a safe outdoor area, well upwind from the home and at a good distance for safety. Avoid potential ignition sources like doorbells, garage door openers, or lighting matches. Designate one person to shut off the main exterior gas valve if easily accessible.

Once evacuated, call 000 from a secure location to report the leak so emergency services can respond. Also promptly phone Leichhardt Plumbing’s gas leak repair and 24 hour emergency plumbing service on 1300 349 338 so our licenced technicians can be dispatched to identify and resolve the leak source.

Do not re-enter the home yourself or allow anyone else to enter. Wait for emergency responders and our technicians to evaluate the property and confirm it is safe before returning inside. Early evacuation and contacting qualified help prevents injuries and limits gas exposure.

Shutting Off the Gas

If a gas leak is suspected and it can be done safely, shutting off the main gas supply valve is crucial to stop leaks before they escalate. Use a wrench to turn the valve a quarter turn clockwise until it is perpendicular to the pipe to shut it off.

This valve, typically located outside next to the gas metre, is a critical point to inspect when a gas leak in your home is detected. This stops the flow of gas into the home.

After shutting off the main gas valve, evacuate immediately and call gas emergency services from a safe location. Also promptly contact Leichhardt Plumbing’s 24 hour plumbing service on 1300 349 338. Alert the operator that you’ve shut off the gas supply, staving off gas leaks before they intensify before they intensify, which will enable our licensed technicians to safely restore service.

Never attempt to turn the gas back on yourself after a leak; instead, call your local gas plumber to safely manage the task. Allow Leichhardt Plumbing’s qualified gas fitters to handle this using specialised equipment to verify pipes are intact and safe. We ensure proper precautions are taken so gas service can resume normally.


Open all doors and windows to allow the gas air to dissipate if it can be done safely. Evacuate everyone immediately and only return once emergency services and Leichhardt Plumbing technicians confirm it is safe. Turning on fans or ignition sources could spark an explosion.

Evacuate the premises to allow it to ventilate, then call 000, followed by our emergency line on 1300 349 338, for assistance with the off-gassing.
