That is the honest short version. The longer version is a triage tree, and it is worth five minutes of your time before you pick up the phone, because a decent share of these jobs end with the homeowner flicking a breaker back on and never needing us at all. Here is how we would work through it if we were standing in your garage.
Quick triage table
| Symptom | Most likely cause | DIY or callout? | Typical cost with us |
|---|---|---|---|
| No hot water, electric system, house otherwise fine | Tripped breaker or failed element/thermostat | Check breaker yourself; element is a callout | Quote on inspection |
| No hot water, gas storage system | Pilot light out, thermocouple, or gas supply | Relight per the tank sticker; if it will not stay lit, callout | Quote on inspection |
| Water warm but not hot | Failing element, thermostat, or tempering valve fault | Callout | Quote on inspection |
| Hot water runs out fast | Sediment, one dead element, or undersized tank | Callout | Quote on inspection |
| Water pooling under the tank | Tank corrosion, end of life | Replacement | Electric storage $1,300 to $2,400 installed; gas storage $1,800 to $3,200 |
| No hot water at 9pm and you cannot wait | Any of the above | After-hours callout | $360 to $560 first hour plus the work |
Is it just a tripped breaker?
Check the switchboard first, because this is the cheapest fix in plumbing. Find the breaker labelled hot water or HWS and see if it has tripped to the off or middle position. Flick it fully off, then back on, and give the tank two to three hours to recover. If the breaker trips again straight away, stop. A breaker that will not hold usually means the element has shorted, often because water has tracked into it through a split in the element sheath. That is a licensed repair, and repeatedly resetting a tripping breaker is how elements burn out switchboard components. One more wrinkle for Queensland homes: many electric tanks run on an off-peak tariff, so if you have used a lot of hot water the tank may simply not reheat until the off-peak window. No fault at all, just timing.
Why has my gas hot water stopped working?
For gas storage systems, the pilot light is the first suspect. Look through the sight glass at the base of the tank. If the pilot is out, follow the relighting instructions printed on the tank itself, and only those instructions. If it relights and stays lit, you are done. If it will not stay lit, the thermocouple has usually failed, which is a genuinely common fault on tanks past the eight year mark and a straightforward licensed repair. Also check the obvious: is the gas isolation valve on the supply line actually open, and if you are on LPG bottles, is the bottle empty? For continuous flow units, check the unit's power supply, because even gas continuous flow systems need electricity to fire, and look for an error code on the controller. Note the code down before you call us, because it usually tells us exactly what to bring.
When is no hot water a repair and when is it a replacement?
If the tank itself is leaking, it is a replacement, full stop. There is no economical way to repair a corroded steel cylinder, and any money spent on a leaking tank is money wasted. For everything else, age is the deciding factor. The pattern we see across Gold Coast jobs is that elements, thermostats, thermocouples and valves are worth repairing on systems under about eight years old, and rarely worth it past ten to twelve. Coastal air and our water conditions are not kind to tanks, so a twelve year old system with a failed element is usually giving you an early warning rather than a one-off fault. If you are in that decision zone, our repair-or-replace page walks the maths through properly. Replacement pricing is published: electric storage $1,300 to $2,400 installed, gas storage $1,800 to $3,200, gas continuous flow $1,900 to $3,500, heat pump $2,500 to $4,500 after rebates.
Can I fix a hot water system myself in Queensland?
Beyond resetting a breaker, relighting a pilot per the manufacturer's instructions, and checking valves are open, no. In Queensland, work on a hot water system, including replacing an element, thermostat, tempering valve or relief valve, is regulated plumbing work under the Plumbing and Drainage Act 2018 and must be done by a licensed person. Gas-side work sits under the Petroleum and Gas (Safety) Regulation and needs a licensed gas fitter. This is not us protecting our patch. Hot water systems combine stored energy, scalding water, electricity or gas, and pressure relief valves that people are tempted to cap when they drip. Getting it wrong is genuinely dangerous, and unlicensed work can void your insurance and appliance warranty.
