  • Gas Leak Detection


Have the gas mains recently been upgraded in your street and discovered your service has been cut off?

This means that a pressure test has been undertaken by the Gas company and they have detected a leak somewhere on your service.

Inconvenient or Potentially Dangerous

From hot water, cooking and home heating to barbeques, pools and outdoor heating, gas is crucial to our everyday operations. Therefore, a disruption to our gas supply can cause a major inconvenience in both domestic and commercial environments. Not to mention that gas can build up in confined spaces and can create a potentially dangerous situation.

When underground natural gas pipes leak, it is often due to external damage to the buried pipe. Digging, excavation and corrosion are a few common causes of natural gas leaks.

Underground gas leaks tend to migrate along the path of least resistance and can migrate through loose soil, sewer lines and buried conduit. Gas leaks can migrate longer distances and become challenging to find.

Priority Plumbing has the diagnostic equipment and experience to locate, repair and reinstate your gas service with minimal disruption to your business and family in a cost-effective, efficient manner.

If you smell gas in the street or on your property before or including the gas meter, you should call the Gas Leaks and Emergency services on 1800 GAS LEAK (1800 427 532) to locate and repair the leak.

Suspect you have a Gas Leak?

Signs of Gas Leak include:

  • High gas bills
  • The pungent or rotten egg smell of gas.
  • You can hear hissing sound coming from gas appliance or nearby areas.
  • Gas pilot light keeps going out

If you smell gas inside your building or home:

  • Open all doors and windows for ventilation.


  • Do not look for a gas leak with a naked flame or other ignition source.

  • Do not turn on or switch off any lights, use a telephone, or use a flashlight, at the risk of causing a spark that could start a gas fire.
  • Do not smoke, light matches, or use a cigarette lighter inside or while on the property.
