Hot Water Not Working but Cold Is Fine
We start at the supply and work inward, ruling one thing out at a time. The order runs like this:
The cold supply
The isolation valve on the pipe feeding the unit gets checked first, because a valve bumped part-closed starves the cylinder before anything downstream makes sense.
Leaks
We inspect the tank body, each joint, each valve and the relief line for water, because a leak changes the whole job.
One tap or every tap
One cold mixer usually means the fault sits at that fixture; cold water everywhere points back to the unit or the water reaching the unit.
Gas or power
How the unit is fueled decides which supply we check. Gas supply faults are a job for a licensed gasfitter, and our gas fitting page explains that licence.
Temperature at the tap
Lukewarm water everywhere often means a valve or a setting, and the tap gets tested once the supply is proven.
The diagnosis covers the water side, the valves and the gas supply, and stops there. Anything beyond that belongs to another trade.

Signs a Hot Water System Is Past Repair
A leak at a valve, a fitting or a replaceable part is a repair. Water coming through the wall of a storage tank means the tank has failed, and the system gets replaced. That dividing line is where every repair-or-replace call starts.
The leak's location decides the answer
A weeping valve or a dripping joint is a part swap. A tank leaking through the tank's own shell is not.
Age and service history weigh on a borderline call
A well-serviced cylinder earns one more repair; a neglected one does not.
Service intervals matter
QBCC guidance points to a five-yearly service by a licensed person, more often where the property draws bore water or rainwater. That interval is advice, not a legal limit.
Repeat faults settle it
A cylinder on a third valve in two years is past the point where repairs pay their way.

What a Replacement Involves Under Queensland Rules
A licensed plumber carries out the replacement, and a licensed gasfitter comes too when the unit burns gas. Queensland classes the job as notifiable work in a home that already exists, which means no council permit and no compulsory inspection.
The paperwork still counts. A Form 4 reaches the QBCC inside ten business days of completion, and the owner receives a copy. Water heaters and tempering valves are regulated work, so the licence is not optional on either side of the job.

Why Stored Water Is Hotter Than Tap Water
Queensland runs two temperatures in a house system. A temperature control device holds the water reaching outlets at 50°C or cooler, while the cylinder stores water at 60°C or hotter to stop Legionella bacteria growing.
The cooler figure is about scalding, and the hotter one is about hygiene. The device is not optional on modern work:
- Any new system, and any replacement, like for like included, needs one fitted.
- A newly installed bath or shower outlet needs one too.
- Swapping a washer or a showerhead does not.

Hot Water on Terraced Cottage Blocks
Cottages here were restored rather than rebuilt from the 1970s onward, and a cylinder often went in with each renovation round. Units of a similar age therefore tend to fail together. Census figures put 1,482 of the suburb's dwellings as separate houses, most of them older weatherboard builds on the hill's cut-in terraces.
Access shapes the job as much as the fault does. Hauling an old cylinder down stairs and setting a new base on a block held up by a retaining wall adds time a flat suburban yard never sees. If the cold shower is part of a bigger reno, our bathroom plumbing page covers that side of the work.

Hot Water Questions Customers Ask
Call (07) 3524 0766What do plumbers check when a Red Hill home has no hot water?
We run five checks in order. First comes the cold supply and the isolation valve, then leaks at the tank, the fittings and the valves. Next we test whether one mixer or every tap has gone cold, then the fuel or power reaching the unit, and finally how hot the water arrives.
Should I repair or replace my hot water system?
A tank that leaks through its own shell has failed, so the whole system is replaced. Faults at the valves, the fittings or other parts are repairs. Age and service history tip a borderline call, and repeat faults on an old unit settle the question.
How often should a hot water system be serviced?
Roughly every five years by a licensed person, and more often where the property draws bore water or rainwater. The interval is a recommendation from the QBCC, not a rule.
Does replacing a hot water system need a permit?
No, a permit is not needed. Queensland treats the job in an existing home as notifiable work, so a Form 4 goes to the QBCC inside ten business days, and the owner receives a copy.
What decides the cost of a hot water repair in Red Hill?
The price turns on two factors: the part that has failed, and whether gas or a temperature control device is in the mix. Flat-rate pricing applies, and a fixed quote before any work starts confirms the figure.
