You step into the shower on a cold Caboolture morning and get hit with ice water. You check the gas hot water system outside and the pilot light is out. Again.
If this keeps happening at your place, you’re not imagining things. Caboolture’s storm season is brutal on gas hot water systems. Between the wind, the rain, and the pressure drops that come with big weather events, pilot lights cop a hiding out here.
Here’s why it happens, how to safely relight it yourself, and when you need a licensed gas fitter to take a look.

Why Pilot Lights Go Out During Caboolture Storms
Most gas hot water systems in Caboolture sit outside on the side of the house. That means they’re exposed to everything our weather throws at them:
- Wind gusts — Strong westerlies and storm fronts blow straight into the burner compartment. One decent gust is enough to snuff out the pilot flame. Homes on exposed blocks in Upper Caboolture and along the D’Aguilar Range cop this the worst.
- Rain ingress — Heavy rain driven sideways by wind gets into the unit. Water hits the thermocouple or burner assembly and the flame dies. Older units with damaged or missing weather shields are especially vulnerable.
- Gas pressure fluctuations — During major storms, gas supply pressure can drop slightly across the network. If your pilot flame is already marginal — running small because of a dirty jet or worn thermocouple — that pressure dip is enough to kill it.
- Faulty thermocouple — The thermocouple is a safety sensor that sits in the pilot flame. When it detects the flame is gone, it shuts off the gas supply. If the thermocouple is worn or corroded, it can misread and shut off the gas even when the flame is fine.
- Blocked pilot jet — Dust, spiders, and insects love to nest in gas appliances. A partially blocked pilot jet produces a weak flame that goes out easily.
How To Safely Relight Your Gas Hot Water Pilot Light
Before you touch anything, read the label on your unit. Every gas hot water system has relighting instructions printed on the casing. Follow those first — they’re specific to your model.
The general process for most systems:
- Turn the gas control knob to OFF — Wait at least five minutes for any residual gas to clear. If you smell gas strongly, do not attempt to relight. Get everyone out and call 000.
- Turn the knob to PILOT — Press and hold the knob down. This manually opens the gas valve to the pilot jet.
- Press the ignition button — Most modern units have a piezo igniter. You might need to press it several times. On older units, you may need a long match or BBQ lighter.
- Hold the knob down for 30 to 60 seconds — This gives the thermocouple time to heat up and register the flame. If you release too early, the gas shuts off and you have to start again.
- Turn the knob to ON — The main burner should fire when the unit calls for heat.
If the pilot lights but won’t stay lit after you release the knob, the thermocouple likely needs replacing. That’s a job for a gas fitter.
When To Call A Gas Fitter
Some pilot light issues are simple. Some are dangerous. Here’s where the line is:
- The pilot won’t stay lit after multiple attempts — Worn thermocouple, faulty gas valve, or a gas supply issue. All need professional diagnosis.
- You smell gas when the pilot is out — Gas pooling around the unit is a safety risk. Don’t try to relight it. Call us immediately.
- The flame is yellow or orange instead of blue — A healthy pilot flame is blue with a small yellow tip. A fully yellow flame means incomplete combustion — carbon monoxide risk. Get it checked.
- The unit is more than 10 years old — Older systems have more wear on safety components. If the pilot keeps failing, it might be time to look at a new gas hot water system or consider switching to a heat pump hot water system.
- Water is leaking from the unit — If you’ve got a leaking hot water system combined with pilot light issues, the tank may be failing internally.
Gas work in Queensland must be done by a licensed gas fitter. It’s not a suggestion — it’s the law under the QLD Plumbing and Gas Regulation. Unlicensed gas work voids your insurance and puts your family at risk.
How To Prevent Pilot Light Problems
- Install a wind guard — A simple metal shield around the burner compartment deflects wind away from the pilot. We fit these as part of a standard gas hot water service.
- Keep the area clear — Don’t stack things around your hot water system. It needs airflow for safe combustion and access for maintenance.
- Schedule annual servicing — A gas fitter checks the thermocouple, pilot jet, burner, and all connections. Small problems get caught before they leave you without hot water.
- Check the weather shield — Make sure the casing panels are intact and sealed. Missing or damaged panels let weather straight in.
- Consider a TMV (tempering valve) test at the same time — If your system has a tempering valve, it needs testing to make sure your water temperature is safe — especially if you have young kids.
Frequently Asked Questions
Is It Dangerous If My Pilot Light Goes Out?
The pilot light going out by itself isn’t immediately dangerous — the thermocouple safety valve shuts off the gas. But if you smell gas near the unit, don’t try to relight it. Leave the area and call a licensed gas fitter. Gas pooling in an enclosed space is an explosion and fire risk.
How Much Does It Cost To Fix A Pilot Light That Won’t Stay Lit?
Most pilot light repairs in Caboolture cost between $150 and $350 depending on the issue. A thermocouple replacement is on the lower end. If the gas valve or control assembly needs replacing, it’s closer to $350 or more. We provide upfront pricing before starting any work.
Can I Convert My Gas Hot Water To Electric To Avoid Pilot Light Problems?
Yes. Many Caboolture homeowners are switching to heat pump hot water systems to avoid gas pilot light issues and reduce energy costs. We can advise on the best replacement option for your home and handle the full installation.
Why Does My Pilot Light Only Go Out During Storms?
Wind is the most common cause. If your unit is in an exposed position without a proper wind guard, storm gusts blow straight into the burner compartment and extinguish the flame. We can fit a wind shield and check the unit’s positioning to reduce the problem.
How Often Should I Service My Gas Hot Water System?
Annual servicing is recommended. A licensed gas fitter checks the pilot assembly, thermocouple, burner, gas connections, pressure relief valve, and anode rod. Regular servicing extends the life of the system and catches safety issues early.
Don’t Put Up With Cold Showers
A pilot light that keeps going out is annoying, but it can also be a warning sign of bigger issues. If yours won’t stay lit or you’re relighting it every time the wind picks up, give us a call. We’ll check the system, fix the problem, and make sure your gas appliance is safe.
