24/7 Emergency Services
If you’ve ever had your hot water system suddenly stop working on a freezing Adelaide morning, you know it’s not just an inconvenience — it’s a full-blown crisis. No one wants to start their day with an unexpected ice-cold shower.
The truth is, hot water systems, like any other home appliance, need regular maintenance to run smoothly. And yet, many homeowners don’t think about servicing until something goes wrong. This blog is here to help you stay ahead of the drama and keep your hot water heater in great shape — because prevention is always cheaper than emergency plumbing.
That’s why it’s important to understand what goes into hot water servicing in Adelaide — and how a little maintenance can go a long way.
If you’ve never booked hot water servicing in Adelaide, you might be surprised at how much longer your system can last with just a little attention every couple of years.
Your hot water system is one of the hardest-working appliances in your home. It runs silently in the background, doing its job without complaint — until it suddenly doesn’t.
Regular servicing helps:
Catch minor issues before they turn into costly repairs
Keep your system running efficiently (aka saving you money on power bills)
Prolong the life of your unit — sometimes by years
Ensure safety, especially with gas systems
Maintain your manufacturer’s warranty (many warranties require service records)
Most homeowners wouldn’t drive their car for five years without a single service. But oddly enough, many do exactly that with their hot water systems. When you think about how often it’s used, that’s kind of like running your car 24/7 without checking the oil.
Routine hot water servicing in Adelaide not only keeps your system running smoothly but also helps you avoid being caught off guard when the weather turns.
For Adelaide homes, where water quality and seasonal changes can impact your system, experts recommend:
First service at 3 years
Then every 2 years after that
Whether it’s gas or electric, most experts agree that hot water servicing in Adelaide homes should begin around year three and continue every two years after.
If your household has high hot water usage (think: long showers, large families, or lots of laundry), you might consider shorter intervals.
These aren’t just arbitrary numbers. Servicing intervals are recommended by manufacturers to ensure your system keeps working as intended. And let’s be honest — a service every couple of years is a lot less painful than a surprise replacement bill.
Wondering what plumbers actually do during a service? It’s more than a quick peek and a thumbs-up.
Here’s what’s typically involved:
Gas pressure and burner testing (for gas systems)
Thermostat and element checks
Inspection of temperature pressure relief (TPR) valves
Water and gas leak detection
Electrical safety inspection
Assessment of sacrificial anodes (more on this below)
Check for sediment buildup
Clean burner assemblies or heating elements
Think of it like a health check for your hot water system. The plumber’s job is to catch signs of wear, prevent corrosion, and make sure everything is running as it should.
Some services even include flushing the tank, which helps remove mineral deposits that collect over time — especially if your home has hard water.
Sounds dramatic, doesn’t it? A sacrificial anode is exactly what it sounds like — a metal rod inside your hot water tank that gives itself up to corrosion so that your tank doesn’t have to.
Here’s how it works:
The anode attracts minerals and impurities that would otherwise eat away at the tank lining.
Over time, the anode corrodes instead of the tank (hence the name “sacrificial”).
Once fully corroded, the anode can’t protect your tank anymore — and corrosion begins where it shouldn’t.
In Adelaide, depending on the local water supply, these anodes typically last around 3–5 years. During a service, your plumber will check the condition and recommend a replacement if needed.
Neglecting the anode is a common reason tanks fail earlier than expected. Swapping it out during a service can help your system last a lot longer — and cost far less in the long run.
Not sure if your system is due? Your hot water heater will usually send out a few cries for help before it completely gives up.
Here are the most common signs:
Inconsistent water temperature (hot one minute, cold the next)
Reduced water pressure
Rust-colored water coming from taps
Strange noises like popping or banging from the tank
Leaks or moisture around the base
Higher-than-normal energy bills
These signs are your system’s way of saying, “Please give me some love.” Booking hot water servicing in Adelaide before things break down completely can save you hundreds — if not thousands — in emergency repairs.
Not all hot water systems are created equal. Adelaide homes often have either gas or electric units, and each type has its own servicing needs.
Burner inspections
Gas pressure and flue testing
Checking for carbon monoxide leaks
Ventilation assessment
Heating element testing
Thermostat check
Wiring and electrical safety inspection
Both types require inspection of valves, anodes, and tank integrity. So regardless of the setup, a professional plumber is still your best bet.
And yes — even tankless systems need servicing. While they don’t have anodes or tanks, they still require flushing and valve checks.
Look, we get it — you have options. But working with a local Adelaide plumber has some serious perks.

Short answer: no. Safety risks — especially with gas or electric systems — make DIY a bad idea. Only licensed plumbers should perform a full service.
Yes. Even though they don’t have tanks, they still need descaling, filter checks, and general inspection to ensure efficiency and safety.
