What Are the Common Gas Fitting Problems & How to Spot Them Early

Are you noticing strange odours near your gas appliances or experiencing irregular heating performance? Gas fitting issues can develop gradually and often go unnoticed until they pose serious risks. In Australian homes, especially in regional areas like Dubbo, safe gas installation and maintenance are essential—not just for convenience but for health and safety. In this blog, we’ll explore the most common gas fitting problems, how to spot early warning signs, and why licensed professionals should always carry out gas work.

The Most Common Gas Fitting Problems in Australian Homes

Gas systems are generally reliable, but like any system, they can develop faults over time. Below are several issues frequently reported in homes across Dubbo and other regional NSW areas.

Gas Leaks

Leaking gas is one of the most serious and potentially hazardous issues. Leaks may occur due to ageing pipework, faulty connections, damaged regulators, or poor workmanship. While natural gas is odourless, a chemical called mercaptan is added to give it a strong sulphur-like smell for detection.

Warning sign: A distinct rotten egg smell, especially near gas appliances or meters.

Faulty Appliances

Gas appliances such as stoves, ovens, water heaters, or space heaters may develop faults due to wear and tear, lack of servicing, or manufacturing defects. These faults may lead to poor combustion, carbon monoxide build-up, or pilot light failure.

Warning sign: Appliances not heating correctly, frequent pilot light extinguishing, or yellow/orange flames instead of blue.

Blocked or Damaged Gas Lines

Gas lines can deteriorate over time or become blocked by debris, moisture, or internal corrosion. Damaged lines can restrict gas flow, leading to appliance malfunction or increased pressure risk.

Warning sign: Appliances underperforming, unusual hissing sounds from lines, or visible damage to gas pipework.

4. Inadequate Ventilation

Many gas appliances require proper ventilation to operate safely. Blocked or poorly designed flues can lead to a build-up of carbon monoxide inside the home—a serious health hazard.

Warning sign: Unexplained fatigue, dizziness, or headaches when using gas appliances.

Improper Installation

DIY gas fitting or work done by unlicensed individuals can result in improperly installed lines or appliances. This not only voids warranties but also creates significant safety and legal risks.

Warning sign: Recent renovations with no record of professional gas work, inconsistent appliance function, or visible DIY pipework.

Why DIY Gas Work Is Illegal & Dangerous in Australia

Gas fitting is classified as a high-risk trade in Australia. In NSW, it is illegal for anyone other than a licensed gas fitter to install, repair, or modify any part of a gas system. DIY gas work breaches these legal requirements and can pose serious safety risks. Faulty fittings, undetected leaks, or incorrect combustion may lead to fires, carbon monoxide exposure, or explosions.

Even simple tasks—such as relocating a gas heater or installing a new cooktop—should only be carried out by a qualified gas fitter in Dubbo. Licensed professionals use calibrated tools, perform safety testing, and follow Australian Standards to help minimise the risk of faults, damage, or harm.

Attempting unlicensed gas work could also void insurance coverage.

What to Do If You Suspect a Gas Leak

If you notice a strong gas smell or suspect a leak, act immediately to protect yourself and others:

• Turn off the gas supply at the main valve if safe to do so.
• Open windows and doors to ventilate the space.
• Do not use electrical switches, matches, lighters, or any naked flame.
• Leave the property and move to a safe area.
• Contact a licensed gas fitter or emergency service to inspect and repair the issue.

Never try to locate or fix the leak yourself. A licensed professional has the equipment to safely test and isolate faults.

The Role of Regular Gas Maintenance & Inspections

Proactive maintenance helps detect gas issues early—before they become dangerous or lead to costly repairs. Scheduling regular inspections by a licensed gas fitter in Dubbo can:

• Identify worn seals, corroded connections, or deteriorating pipework.
• Confirm that appliances are functioning efficiently and safely.
• Test for gas leaks using calibrated equipment.
• Check ventilation systems and carbon monoxide levels.

Routine checks are especially important for older homes, investment properties, and households using multiple gas appliances. For landlords, regular gas inspections also support compliance with residential tenancy laws and duty of care obligations.

Signs That Your Gas System Needs Attention

Early detection is key to avoiding serious faults. Contact a licensed gas fitter if you notice any of the following:

• A consistent gas smell indoors or near appliances.
• Appliances that don’t stay lit or perform inconsistently.
• Discoloured flames or soot marks around gas outlets.
• Unusual headaches or drowsiness when using gas heating.
• Unexplained spikes in your gas bill.

Even if the signs seem minor, they can point to issues that may worsen over time. A professional inspection helps clarify the cause and recommends safe, compliant solutions.
