Nothing ruins a morning like a cold shower. Gas hot water systems are generally reliable, but a few common issues account for most of the callouts we get from Rozelle, Balmain, Leichhardt, and neighbouring Inner West suburbs.
Common symptoms and what they usually mean
No hot water at all often points to a pilot light or ignition failure. Inconsistent temperature can mean a faulty thermostat or a tempering valve issue (a topic we’ve covered in detail before). Discoloured or rusty water, or a rotten egg smell, are signs that need immediate professional attention rather than a DIY check.
What’s safe to check yourself
You can safely check whether the pilot light is out and whether the gas supply to your property is on. Beyond that, gas hot water systems involve combustion, ventilation, and gas pressure components that legally require a licensed gas fitter to inspect or repair.
Why this isn’t a DIY job
Unlike a dripping tap, gas appliances carry real safety risks if serviced incorrectly, and in Australia, only a licensed gas fitter can legally carry out repairs on gas hot water systems. Whether you’re in a Birchgrove apartment or a Balmain East terrace, if you’re noticing any of the symptoms above, it’s worth booking a proper inspection rather than waiting for it to fail completely, especially heading into the cooler months.
