FAQs

Do I need a licensed gas fitter to install an appliance?
Yes, gas appliance installation must be completed by licensed gas fitters to meet Australian safety standards. Incorrect installation can void manufacturer warranties and create serious safety risks.
But that doesn’t mean you should pay high prices for gas appliance installation. Thanks to our buying power and experience, we’re able to keep prices low without cutting corners on quality, testing or certification.
What are the signs of a gas leak?
Common signs include:
- Smelling gas (a rotten egg smell)
- Hissing sounds near appliances
- Dying plants near gas lines
- Above-average gas bills
- Dizziness, headaches, or nausea
If you suspect a leak, turn off the gas supply if safe to do so and contact Mainline Plumbing immediately. We’ll send a licensed gas fitter out to inspect the system and locate the source properly. Where possible, we’ll repair the problem on the spot.
How often should I have a gas inspection?
Gas inspections are recommended for rental properties, older homes, and commercial buildings, or whenever you’re unsure about the condition of your system. Regular inspections help you catch issues early:
- Wear and tear
- Poor ventilation
- Non-compliant installations
- Loose connection points
If you’re not sure when your property last had a gas inspection, get in touch to schedule a visit from Mainline Plumbing.
Do you repair gas hot water service systems?
Yes. We install, repair, and replace gas hot water service units for residential and commercial properties across Bunbury and the South West.
If you’re thinking about an upgrade or experiencing hot water issues, call us for a no-obligation chat. We’ll talk through your options and help you make the right decision for your property, budget, and usage needs. Because we’re independent and work with all major brands, you’re guaranteed to get honest advice and the best prices.
