Elements and Valves
We replace failed heating elements, thermostats and tempering valves on storage units, which restores full heat in a single visit and leaves a healthy cylinder in place to finish its years.

First Moves When the Tap Runs Cold
Work through these in order, and stop the moment anything feels unsafe.
Check more than one tap
A cold shower at the back of the house with hot water elsewhere is a fixture problem, not a system failure.
Check the hot water breaker in the meter box
A tripped breaker or a knocked-off switch explains a surprising number of cold tanks.
Shut the isolation valves if the unit is leaking
Two small taps at the cold inlet stop a weeping cylinder flooding the laundry while you wait.
Leave the property if you smell gas
A gas smell near the unit is not a hot water problem, and our gas leaks page has the steps.
What Usually Fails
Causes range anywhere from a five-minute repair to a complete replacement, though most fall on the simpler end.
An off-peak switch or tripped breaker
Tanks on off-peak tariffs only heat during set hours, so a supply hiccup overnight shows up as a cold morning shower.
A failed element or thermostat
The parts that do the heating wear out, and a tank that goes from hot to stone cold overnight usually points here.
A pilot light that will not stay lit
Gas units with an ageing thermocouple drop their pilot and give no heat at all.
A valve failure or a split cylinder
A relief valve stuck open dumps hot water down the drain, and a split tank is the biggest job on the list.
What You Can Check Yourself
Three checks are safe before you ring anyone, and together they rule out half the common causes:
The hot water switch in the meter box
If it has tripped or been knocked off, the tank stays cold no matter how healthy it is.
The pilot window on a gas unit
Follow the relight steps on the label; if the pilot lights and holds, the fault sits further along the line.
The pipework around the tank
Feel the pipes, never the flue. Water on the floor means something physical has failed and the unit needs a plumber.
When to Ring Us
Ring straight away in any of these cases:
- Water pooling under the unit, or a relief valve running hard.
- A tank gone cold with a full house needing showers.
- Any smell of gas near the unit, which means leaving first and calling from outside.
A tank that heats nothing but leaks nowhere can wait for a booked visit, and we will find the earliest time we can.
What We Do On the Day
Our work covers every part of a hot water system, from a single valve to a whole new unit:
Solar Roof Circuits
Solar systems add pumps, sensors and roof collectors to the fault list, and we trace a cold-solar fault from the tank up to the roof and back before quoting anything.
Cylinder Splits
A tank leaking from the base is beyond saving, so we shut it down safely, stop the water damage spreading, and quote the new unit on the same visit wherever we can.
Full System Upgrades
When a household has outgrown a small unit or the old tank has simply finished, we size and install a replacement, quote the job first, and take the old cylinder away.

Common Hot Water Failures
Stone Cold Overnight
A tank that was hot yesterday and dead today has usually lost its element or thermostat, and both are standard parts our vans can carry and fit on the first visit.
Lukewarm, Never Hot
Water that runs warm but never properly hot usually means a thermostat set too low or one failed heating leg, and the fix is often a setting or a single part.
Water Under the Unit
A weeping relief valve can be swapped on the spot, but water seeping from the tank base means the cylinder has rusted through, and that tank has reached the end of its run.
No Water From Hot Taps
Hot taps running dry points to a supply or valve fault rather than the heater itself, so we isolate which side of the system has failed before any work begins on your pipework.
Why the First Cold Snap Bites Here
Three decades of family homes
Building spread across the hills around the old village from the 1970s into the 1990s, and a storage tank fitted in that first wave is now long past its use-by date.
A solar-heavy postcode
The federal tally lists close to 972 solar hot water systems for this postcode against about 430 heat-pump units, so roof collectors, pumps and sensors age alongside the tanks they feed.
The season finishes them off
Frost is rare here, averaging far less than one frost day annually, but the first genuinely cool morning makes an ageing element labour harder than at any other point in the year, and the oldest tanks tend to give out then.
Why It Matters
Three reasons a dead tank should not sit until next week:
A failed tank can flood while you sleep
A split cylinder feeds itself from the mains, so the water keeps coming until somebody shuts the isolation valve, and a laundry floor shows the damage by morning.
Cold water hits a family fast
With school-age kids across most of the suburb, one dead tank takes out showers, washing-up and bath time in a single morning, which is why we treat it as urgent.
The right fix saves money
Swapping a whole cylinder because one valve failed costs far more than the valve, and we always tell you which side of that line your unit sits on before quoting.

Cold Tap Questions
Call (07) 3067 4119Why does my Petrie hot water fail on cold mornings?
Because a tired element works hardest on the first cool morning of the season, and the units fitted when this suburb's housing belt went up are the ones now feeling their age.
Is no hot water in Petrie an emergency?
It becomes one when the cylinder is leaking or a relief valve is running hard, because a split tank keeps feeding itself from the mains and can flood a laundry overnight.
Can I relight the pilot light on my gas hot water unit myself?
Yes, following the relight steps printed on the unit's label is safe, but if you smell gas at any point while you are there, leave the property straight away and call us from outside.
Does Energex control my off-peak hot water in Petrie?
It can, because plenty of storage tanks heat on an off-peak tariff that the network switches, so a supply interruption rather than a fault can leave a full tank cold overnight.
How do I know if my cylinder is beyond saving?
A tank weeping from its base after decades of work has usually rusted through and is past saving, while a cylinder in good condition with one failed part is worth the repair instead.
