A gas leak isn’t always easy to identify. While a strong gas smell can be an obvious warning sign, some leaks may be difficult to locate because they occur behind walls, beneath floors, around fittings, or in less accessible parts of a gas installation.
If you suspect a gas leak, do not attempt to locate or repair it yourself. Gas-related work should be handled by appropriately licensed professionals. Energy Safe Victoria advises people responding to an indoor gas leak to notify the gas distributor, evacuate the building, avoid ignition sources, and, if it is safe, isolate the gas supply at the meter.
For homeowners and businesses in Melbourne, professional gas leak detection can help identify the source of a suspected leak and determine the appropriate repair.
Why Can Some Gas Leaks Be Difficult to Find?
Gas doesn’t always escape from a clearly visible pipe or fitting. A leak may occur in a concealed or difficult-to-access location, making it challenging to identify its exact source.
Potential locations can include:
- Pipe connections
- Gas appliance connections
- Valves and fittings
- Pipes behind walls
- Areas beneath floors
- External gas pipework
- Damaged or deteriorated components
A professional assessment is important when the source isn’t immediately obvious.
Signs You May Have a Gas Leak
Knowing the warning signs can help you respond quickly.
Unusual Gas Smell
A noticeable gas odour should never be ignored. If you suspect escaping gas, treat the situation seriously and follow appropriate safety procedures.
Hissing or Whistling Sounds
A hissing sound near a gas pipe, fitting, or appliance may indicate escaping gas.
Appliance Problems
Unexpected changes in the operation of a gas appliance may indicate that it requires professional inspection.
Unexplained Damage or Changes Around Pipework
Physical damage to gas pipework or fittings can potentially create a safety issue and should be assessed by a qualified professional.
Symptoms of Carbon Monoxide Exposure
Carbon monoxide is different from natural gas and cannot be relied upon to have a smell. Problems with gas appliances or flues can create carbon monoxide hazards, which is another reason gas appliances should be inspected and maintained by qualified professionals.
How Do Professionals Detect Hidden Gas Leaks?
When a gas leak isn’t immediately visible, a qualified gas professional can use specialised detection equipment and systematic testing methods to help locate the source.
1. Initial Safety Assessment
The first priority is safety. A professional will assess the situation and determine whether the area needs to be evacuated or isolated.
Energy Safe Victoria’s guidance recommends eliminating potential ignition sources and establishing natural ventilation where appropriate. It also specifically advises against using electrical switches, doorbells, garage door openers, or mechanical fans during an indoor gas-leak response.
2. Gas Detection Equipment
Specialised gas detection equipment can help identify the presence and concentration of gas in different areas.
This can be particularly useful when there is no obvious visible source.
3. Systematic Inspection of Pipework
A professional can inspect accessible pipework, fittings, valves, connections, and appliances to narrow down where the leak may be occurring.
This approach can help identify problems that aren’t immediately apparent.
4. Testing and Verification
Once a suspected leak has been identified, appropriate testing can help determine whether the gas system is safe and whether further repair work is required.
Gas systems should not simply be switched back into service after an incident without the appropriate professional checks. Energy Safe Victoria specifically warns against reopening gas valves that were closed during an incident until qualified personnel have completed the necessary integrity testing and relighting process.
What Should You Do If You Suspect a Gas Leak?
Gas leaks require a different response from ordinary plumbing problems.
If you suspect an indoor gas leak:
- Avoid flames, sparks, and other ignition sources.
- Do not operate electrical switches or appliances.
- Evacuate the building if required.
- Contact your gas distributor to report the gas emergency.
- If safe to do so, isolate the gas supply at the main isolation valve.
- Have the installation inspected by an appropriately licensed professional.
The Victorian Government advises residents to find their gas distributor to report gas leaks or other gas emergencies, or call 136 186.
Victoria has three gas distribution businesses, with service areas covering different parts of the state: Australian Gas Networks, Multinet and AusNet Services.
If there is an immediate threat to life or property, call 000.
