In Victoria, there are a variety of gas pipes that range in age and are often made with different materials.

Some sections of low-pressure gas networks are made of cast-iron and have been supplying gas since the 1880s. These older pipes can become affected by water during wet weather and are the main cause of water-related gas supply issues.

When water gets into gas pipes, customers may experience outages and be unable to use gas appliances needed for activities such as cooking, heating and bathing. Appliances may also be permanently damaged by water entering gas lines or lack of gas supplying the appliance.

Victorian gas customers should contact their local gas distributor to report faults. Who your gas distributor is, is determined by where you live. Visit the site for more information.

If you’ve experienced an outage, you may have to arrange for pilot lights to be relit on appliances. Refer to the product manual of your appliance for more information. Some distributors may offer assistance with relighting pilot lights. If you have hydronic heating, it may take a long time for it to heat back up.

Distributors are regularly working to upgrade networks, to limit the disruption caused by poor network assets such as gas pipes. Some gas mains in Victoria are currently scheduled to be converted to high pressure and some distributors are installing siphons to remove water from mains lines.

Distributors may also offer free electric heaters to customers with gas heaters that have been affected. You may also choose to change from gas to electric appliances at your own cost.

You may be entitled to compensation if you have experienced gas outages. Gas supply is not guaranteed in Victoria, however, if distributors do not meet their agreed service level, they must pay compensation to customers in the form of a Guaranteed Service Level (GSL) payment.

GSL payments are applicable to outages only. Customers are not entitled to GSL payments for low gas pressure.

You may also be entitled to compensation if your property is damaged due to upgrade works.
