Detecting Gas Leaks
Prompt detection of gas leaks is critical to ensure the safety and prevent hazards in your home. A natural gas leak in its pure form is odourless, so if you smell gas, it’s due to an odorant called mercaptan added to the gas, which helps identify leaks. Symptoms of a gas leak may include:
- A strong odor resembling rotten eggs signalling a potential gas leak in your vicinity
- Hissing, whistling or roaring sounds coming from appliances or pipes
- Dead plants or grass, or dirt blowing around gas lines outside
- Flames emerging near the gas line from your gas stove burners that are typically blue
- Pilot lights that frequently blow out
- Increased moisture inside of windows near gas appliances
To reduce the risk of carbon monoxide (CO) exposure, it’s wise to get your heater serviced annually if it’s over 10 years old, or every two years for newer models. We also advise installing an indoor gas safety device like a gas detector or carbon monoxide detector, especially for space heaters without flues. If you suspect gas leak issues, contact North Ryde Plumbing for servicing your heater and inspecting your devices to ensure your gas systems are safe.
Signs of Gas Leaks
A prominent indicator of a gas leak is a strong rotten egg odour, a result of the added mercaptan odorant. Additional indicators for performing gas leak checks:
- A hissing or whistling sound coming from appliances or lines as they off gas
- Dirt blowing around outside gas lines
- Unusual moisture collecting inside windows
- Flames from gas stove burners that burn yellow/orange instead of the typical blue
- Frequent blowing out of pilot lights
If there are no clear signs but gas issues are suspected, evacuate immediately and contact emergency services.
Avoid using phones, operating light switches, or igniting flames near a suspected gas leak, as they could trigger an explosion.
Testing for Gas Leaks
There are a few methods available to detect gas and test whether gas leaks exist. Professional gas fitters identify gas leaks using specialised equipment to perform thorough checks and pinpoint any issues.
Chemical smoke tests involve blowing smoke around appliance connections, valves, and joints; the smoke moving towards a leak helps pinpoint its location.
Leaks can also be detected by the formation of bubbles at the site.
Gas fitters use combustion gas analysers to sample and test the exhaust fumes from gas appliances, detecting even subtle issues. This helps determine if dangerous gases are escaping or builds up exist.
Installing detectors at home is crucial to avoid the risk of carbon monoxide poisoning and to prevent unchecked leaks from driving up gas bills.
Arrange an inspection with your gas supplier or North Ryde Plumbing for any gas leak or appliance issues at your residence. Our licensed technicians detect gas leak your lines and make sure they’re equipped with the proper tools and expertise to resolve any issues.
Maintaining and Servicing Gas Appliances
Regular maintenance and servicing of your gas heater are vital to ensure energy efficiency and safe operation. It’s crucial to adhere to the maintenance guidelines and safety recommendations provided by appliance manufacturers.
Gas stoves, hot water systems, and similar appliances over 10 years old need to be serviced annually by a licensed gasfitter. Newer appliances should be serviced every two years. A qualified technician’s maintenance check includes:
- Inspecting gas burner elements, pilots, pipes, valves, and connections for any wear or issues
- Cleaning key components, particularly the heat exchanger
- Testing functionality and safety features
- Ensure open-flued gas exhaust systems are unobstructed and clear, an essential check during routine servicing.
Using a licensed gas fitter to check your gas system during maintenance is strongly advised. Our technicians at North Ryde Plumbing have extensive training and experience servicing all common gas appliances. We use advanced diagnostic tools to detect any problems not visible through standard checks.

Carbon Monoxide Exposure Prevention
Carbon monoxide, which can also be released by faulty gas appliances, is a dangerous, odourless gas. Install carbon monoxide detectors throughout your home, especially near bedrooms, as a critical safety measure. If the alarm sounds, evacuate immediately and off call licensed professionals once outside.
Carbon monoxide poisoning symptoms include headaches, dizziness, nausea, and confusion. Prioritise safety by shutting off the gas supply and re-enter only after professionals have deemed it safe.
Seek immediate medical attention if carbon monoxide poisoning is suspected.
Regular servicing of gas appliances, including natural gas LPG devices by qualified technicians at North Ryde Plumbing, can prevent carbon monoxide risks. We offer full safety inspections and maintenance to provide peace of mind your systems are not exposing you to this dangerous gas.
Gas Leak Emergency Protocols

- Immediately evacuate - ensure everyone exits to a safe area outside your home, distanced from the leak.
- Avoid using any electrical devices, as these could spark an explosion.
- Ventilate the area letting in fresh air by opening all doors and windows if it is safe to briefly re-enter the space.
- Call 000 from outside the building to reach emergency services.
- If it is safe to do so, turn off the gas supply at the meter or individual appliances.
