In Australia, gas is a major source of energy for cars and households to run smoothly and efficiently. A 2017 report from Energy Networks Australia found that 70% of households are connected to a gas network or use bottled gas to run major heating appliances such as stoves and hot water systems. 

Aside from being an effective source of energy, using gas comes with several more advantages, especially if talking about cost. This is because gas costs approximately half the amount of a fully electrically powered home. It is a lot cheaper and if used interchangeably with electricity, it will definitely lower the electricity bill. Taking care of that gas connection or gas tank is very important to prevent costly leaks and dangers. There might be times when a defect might just pop out of nowhere with little sign of an issue, so keep an eye out for these five major signs of a gas leak.

  1. Smell of Gas

The smell of gas is the most obvious sign of a gas leak at home. This is because gas tanks and gas connections should have protective accessories or parts that avoid this kind of issue. The smell of gas is a sign that these accessories might be worn out already or defective which results in a leak. 

  1. Health Problems

One of the major signs of a gas leak within and around the house or the property is a decline in the health of people living in it. What are the physical manifestations? Sudden dizzy spells or nausea, difficulty in breathing, and flu-like symptoms are the signs that homeowners and housemates should look out for. These symptoms can lead to major health issues if the leak is not fixed immediately because gas emissions are not good for our health, especially the respiratory system.

  1. Dead Plants

Another sign that gas users must look for is if plants are not thriving inside or outside the house. If the plant was thriving and flourishing before and no other growing conditions have changed, there could be a leak. Find the source of the leak or call a professional plumber to look for it and have it fixed immediately. 

  1. Bubble Method

The Bubble Method is an old and tested way to determine if a gas connection or the gas tank has a leak. If a household member suspects that there is a leak, it is best to try this method. Mix dishwashing liquid with water in a container, turn on the valve for the gas connection or gas tank, wipe the part of the pipe where the suspected leak is, and if it bubbles, it means there is a leak. 

  1. Hissing Sound 

A properly installed gas connection or gas tank should be secured and safe to use; however, over time, the parts of the connection or tank may become worn or damaged, leading to a leak developing. A hissing sound is one of the major signs of leaking and the easiest to distinguish. The sound of the leak can actually signify that there is a substantial leak on the gas connection, which will only become worse if not repaired immediately. 


To this end, this article is a reminder to always be observant and proactive. While gas has its perks, it also has its dangers. A small leak can grow into a bigger one that can lead to dangerous circumstances. It can cause serious health problems or worse, death. Such dangers can be avoided by having your gas appliances regularly maintained by a professional plumber, particularly if you believe there may be an issue.
