There is never a good time to lose hot water. One minute everything is fine - the next you are standing in a freezing cold shower wondering what went wrong.
For many Brisbane homeowners and landlords, the first question is usually:
“Do I call a plumber or an electrician?”
The answer depends on the symptoms. Some hot water problems are plumbing related, while others involve electrical faults. Knowing the difference can save time, reduce unnecessary callout costs, and help get the problem fixed faster.
Before You Call Anyone, Check These 3 Things
Before calling anyone, there are a few simple things you can safely check yourself.
1. Check Other Taps
Try the:
- kitchen sink,
- bathroom taps,
- shower,
- laundry tap.
If there’s no hot water anywhere in the house, the issue is likely with the hot water system itself.
If only one tap is affected, it could simply be a faulty mixer or tap fitting.
2. Check the Switchboard
Older electric hot water tanks are often connected to their own circuit breaker.
Look for:
- tripped safety switches,
- circuit breakers that have flipped off.
You can reset the breaker once if safe to do so.
If it trips again immediately, stop resetting it and contact a professional.
3. Look for Leaks Around the Tank
Inspect around the base of the hot water system for:
- water pooling,
- dripping pipes,
- rust stains,
- damp concrete.
Even small leaks can become major problems if ignored.
Should You Call a Plumber or Electrician?
This is where many homeowners become unsure.
The good news is that most hot water tank problems are usually handled by a plumber first.
Call a Plumber If You Notice:
- No hot water at all
- Water leaking around the tank
- Rust-coloured hot water
- Low hot water pressure
- Strange noises from the tank
- Hot water running out too quickly
Older electric storage tanks can develop:
- internal corrosion,
- faulty valves,
- thermostat issues,
- sediment buildup,
- or worn heating elements.
A licensed plumber can diagnose most of these problems and advise whether the system can be repaired or needs replacing.
Call an Electrician If You Notice:
- Safety switches repeatedly tripping
- Burning smells near the system
- Sparking or melted wiring
- No power to the unit
These signs may indicate:
- faulty wiring,
- damaged electrical components,
- or problems with the heating element circuit.
If there’s any sign of electrical damage, turn the power off immediately and contact an electrician.
Many Brisbane Homes Still Use Older Hot Water Tanks
A large number of Brisbane homes still rely on traditional electric storage hot water systems
While they’re generally reliable, older tanks don’t last forever.
Most systems last around:
- 8 to 15 years,
depending on maintenance, water quality, and usage.
As systems age, they often become less efficient and more prone to:
- leaks,
- heating problems,
- rust,
- and rising electricity bills.
Repair or Replace?
Sometimes a repair makes sense.
But in older systems, replacement can often be the more cost-effective option — especially if:
- the tank is leaking,
- repairs are becoming frequent,
- the system is heavily corroded,
- or the unit is over 10 years old.
A qualified plumber can usually tell fairly quickly whether the system is worth repairing.
Why This Matters for Brisbane Property Owners
Hot water failures are one of the most common maintenance issues in rental properties.
For landlords and property managers, acting quickly helps:
- keep tenants happy,
- reduce emergency repair costs,
- prevent water damage,
- and avoid bigger maintenance problems later.
Many Brisbane property management companies recommend replacing aging hot water systems before they fail completely.
Preventative maintenance is almost always cheaper than an emergency replacement.
Losing hot water is frustrating, but the problem is often easier to identify than most homeowners think.
As a simple guide:
- Leaks, low pressure, rusty water, temperature issues → Call a plumber.
- Tripping power, burning smells, electrical faults → Call an electrician.
And if you’re unsure? A qualified plumber is usually the best place to start.
