Australians rely heavily on their water heaters for everything from daily showers to keeping the laundry clean. In fact, heating water accounts for a significant chunk of household energy use. But these convenient appliances can also pose a safety risk. Gas leaks from water heaters, while uncommon, can be dangerous if left undetected.
This article will equip you with the knowledge to identify the telltale signs of a gas leak in your water heater so you can take action and keep your home safe.
How Does A Gas Leak Happen?
A gas leak is an unintended release of natural gas, propane, or other flammable gases from pipes, appliances, or storage containers. Gas leaks are extremely dangerous because these gases are highly combustible. When mixed with air in the right proportions, a small spark can ignite the gas, causing fires or explosions that damage property and threaten lives.
In water heaters, gas leaks can occur due to damaged or corroded gas valves, loose fittings, or cracks in burner assemblies. Improper installation or lack of maintenance increases the risk of leaks. Water heaters commonly use natural gas, which is mostly methane. Propane is sometimes used in rural areas. Both are odourless, so utility companies add mercaptan to give it a “rotten egg” smell that helps detect leaks.
Inhaling these gases causes flu-like symptoms, dizziness, and fatigue and replaces oxygen in the blood in high doses, leading to asphyxiation. Gas buildup in confined spaces creates a risk of carbon monoxide poisoning.
To minimise these hazards, proper use and regular professional inspections of gas-powered water heaters are critical. Any suspected gas leaks require immediately evacuating the area and contacting the gas company.
Common Signs of a Gas Leak
Unusual Smells
One of the most noticeable signs of a gas leak is the distinct smell of rotten eggs or sulphur. This odour is added to natural gas and propane to help detect leaks since these gases are naturally odourless.
Hissing Sounds
If you hear a hissing, whistling, or whooshing sound near your water heater, it could indicate a gas leak. These sounds occur when gas escapes from a damaged or loose fitting.
Visible Damage or Corrosion
Inspect your water heater regularly for signs of visible damage or corrosion. Rust, cracks, or dents on the heater’s surface can lead to gas leaks.
Pilot Light Issues
If your water heater’s pilot light frequently goes out or is difficult to relight, it may be due to a gas leak. A malfunctioning thermocouple or a clogged pilot tube can also cause this issue.
Increased Gas Bills
If you notice a sudden increase in your gas bills without a corresponding increase in usage, it could be a sign of a gas leak. Compare your current bills to previous ones to identify any unexplained spikes in consumption.
Health Symptoms Associated with Gas Leaks
Gas leaks can cause various physical symptoms in individuals exposed to the gases. It is crucial to be aware of these symptoms and seek immediate medical attention if they occur. Some of the most common health symptoms associated with gas leaks include:
Headaches, Dizziness, and Nausea
Exposure to gas can cause headaches, dizziness, and nausea. These symptoms may be mild initially but can worsen with prolonged exposure.
Breathing Difficulties and Fatigue
Gas leaks can lead to difficulty breathing, shortness of breath, and fatigue. These symptoms occur when the gas displaces oxygen in the air, making it harder for the body to obtain sufficient oxygen.
Eye and Throat Irritation
Gas exposure can cause eye and throat irritation, resulting in watery eyes, a burning sensation, and coughing.
If you experience any of these symptoms and suspect a gas leak, it is essential to leave the affected area immediately and seek fresh air. Call emergency services and your gas company for assistance. Prompt medical attention is crucial to prevent further harm to your health.
Preventative Measures to Avoid Gas Leaks
Taking preventative measures is essential to minimise the risk of gas leaks in your water heater. Regular maintenance routines and professional inspections can help identify potential issues before they escalate into dangerous situations. Some key preventative measures include:
Regular Maintenance Routines
Establish a regular maintenance routine for your water heater. This should include checking for any visible damage, corrosion, or loose fittings. Ensure that the area around the water heater is clean and free from flammable materials.
Professional Inspections and Servicing
Schedule professional inspections and servicing of your water heater at least once a year. A qualified technician can identify and repair any potential issues, such as gas valve malfunctions or pilot light problems. They can also perform necessary maintenance tasks, like cleaning the burner assembly and checking the gas pressure.
Checking for Warning Signs
Periodically check for warning signs of gas leaks, such as unusual smells, hissing sounds, or visible damage to the water heater. Be vigilant about any changes in the heater’s performance or appearance. If you notice any warning signs, contact a professional immediately for assistance.
Ensuring Safety and Efficiency in Your Home
Ignoring a gas leak in your water heater is like playing hide-and-seek with a fire hazard. Luckily, these sneaky leaks often give themselves away with a rotten egg smell, hissing noises, or even wilting houseplants near the appliance. If you suspect a leak, don’t wait! Natural gas is no joke, and even small amounts can be dangerous.
