Why We're the Wilson Specialists
Sydney Calls On
Wilson has been building hot water systems in Australia since 1930 — that's over 95 years of Aussie-made history behind every tank we work on, including systems from Hocking, a brand Wilson acquired along the way. Their electric storage units are built tough, with copper and stainless steel cylinders designed to handle Sydney's water. We've been repairing and replacing them for more than 40 years, so when your Wilson system plays up, we already know what's going on inside it.
A trusted name in Sydney hot water for decades.
Wilson hot water systems: lifespan & tank types
For over 40 years, Emergency Hot Water Repairs has repaired, serviced and installed Wilson hot water systems throughout Sydney.
💡 How long should my Wilson hot water system last?
The answer depends on the type of system, installation quality, maintenance, water conditions and household hot water usage.
Average lifespan of a Wilson hot water system
| System Age | What We Recommend |
|---|---|
| Under 10 years old | Repair is usually the better option |
| 10 to 15 years old | Repair or replace, depending on the fault |
| 15+ years old | Replacement is often more cost-effective |
These are average lifespans. Some systems fail earlier due to poor installation or neglected maintenance, while well-maintained Wilson storage tanks can last much longer.
Our experience
We have replaced Wilson systems that failed after seven or eight years, and we have also seen well-maintained Wilson tanks still working after more than 20 years. The difference is usually installation quality, water conditions and whether the system has been looked after.
Repair or Replace: What We Look At
Not every ageing Wilson tank needs replacing. When we're called out, we look at the age of the system, the fault, and the condition of the tank itself before recommending anything.
| Factor | Repair Usually Makes Sense | Replacement Usually Makes Sense |
|---|---|---|
| Age | Under 10 years old | 15+ years old |
| Fault | Element, thermostat or valve failure | Tank leaking or rusted through |
| Cost | Repair is a fraction of a new system | Repeated repairs adding up |
When Repair Makes Sense
If your Wilson system is under 10 years old and the fault is a failed element, thermostat, or pressure relief valve, repair is almost always the more cost-effective option. These are common, well-understood faults on electric storage tanks, and parts are usually straightforward to source.
When Replacement Makes Sense
Once a Wilson tank is leaking from the cylinder itself, or is well past the 15-year mark, replacement is usually the smarter long-term move. A corroded or rusted-through tank can't be repaired — only the fittings around it can.
Our experience
In Sydney's Eastern Suburbs, we've replaced Wilson elements that failed after just seven or eight years, and we've also serviced well-maintained Wilson tanks still going strong after more than 20. The difference usually comes down to water quality, installation, and whether the system has had any maintenance at all.
Wilson systems we repair & service

Weeping, dripping or stuck pressure relief valves are one of the most common Wilson faults we see. Quick diagnosis and same-day replacement.

Common Wilson hot water system failures
Once you know the system type, the next step is working out whether the fault is repairable. These are the Wilson problems we see most often across Sydney homes.
1. Cylinder Corrosion
Common Symptoms
Water leaking from the cylinder, rust around the base, brown water or pooling beneath the unit.
How to Help Prevent It
Replace sacrificial anodes when required. Have the system inspected every few years and repair leaking valves promptly.
Important
Once a storage cylinder begins leaking, replacement is usually the only practical option.
2. Worn Sacrificial Anode
Common Symptoms
Older system with no previous anode replacement, rusty water or premature tank corrosion.
How to Help Prevent It
Inspect the anode every 3 to 5 years and replace it before it is fully depleted.
3. Heating Element Failure
Common Symptoms
No hot water, lukewarm water, slow recovery or the circuit breaker tripping.
How to Help Prevent It
Test the element if heating performance changes and replace ageing elements before complete failure.
4. Thermostat Failure
Common Symptoms
No hot water at all, water not hot enough, water too hot, inconsistent temperature or hot water running out sooner than normal.
How to Help Prevent It
Have the thermostat tested if water temperature changes. Never bypass a thermostat, as it is an essential safety device.
5. Pressure Relief Valve Failure
Common Symptoms
Constant dripping from the overflow pipe, water running from the relief valve, increased water bills or reduced efficiency.
How to Help Prevent It
Replace leaking valves promptly and have the valve checked during servicing.
6. No Hot Water at All
Common Symptoms
Cold water only, tripped circuit breaker, or the element failing to heat the tank at all.
How to Help Prevent It
Have the element and thermostat checked every few years — most element failures give little warning before they fail completely.
7. Overheating & Safety Switch Tripping
Common Symptoms
Circuit breaker trips repeatedly, water scalding hot, or a burning smell near the unit.
How to Help Prevent It
Don't keep resetting a tripping breaker — this usually points to a failing element or thermostat that needs inspection before it becomes a safety issue.
8. Water Quality
Common Symptoms
Shorter system life, corrosion, noisy operation, poor performance or premature component failure.
How to Help Prevent It
Install the correct system for local water conditions, maintain sacrificial anodes and service the system regularly.
9. Tempering Valve Problems
Common Symptoms
Lukewarm water, sudden temperature fluctuations, reduced hot water flow, hot water running out quickly or different temperatures at different taps.
How to Help Prevent It
Have the tempering valve checked during servicing and replace worn or faulty valves.
Tip
Many homeowners think the hot water system has failed when the real problem is a faulty tempering valve.
Repair or replace?
Not every older Wilson needs replacing. Heating elements, thermostats, pressure relief valves and tempering valves can often be repaired at a fraction of the cost of a new system.
However, if the storage cylinder has rusted through and is leaking, a replacement and new installation is generally the only practical option. We supply and install all current Wilson models with same-week availability on most units — we'll remove your old system, install and test the new one, and leave you with full warranty documentation.
Repair when it makes sense
At Emergency Hot Water Repairs, we do not recommend replacing a hot water system simply because it is old. We inspect the fault first, explain the options and recommend repair where repair is still the sensible choice.

Wilson hot water — common questions
Why has my Wilson hot water system stopped working?
Wilson systems can stop working due to thermostat failure, a tripped circuit breaker, failed heating element, sediment buildup, or a faulty pressure relief valve. Our technicians carry the most common Wilson parts and can usually diagnose and fix the issue in a single visit. Call us on 02 9344 6602 — we're available 24/7.
Can I still get parts for my Wilson system?
Yes. We carry the most common Wilson parts — elements, thermostats and pressure relief valves — on our trucks, so most repairs are done in a single visit. For less common parts, we can usually source them within a day or two.
How long do Wilson hot water systems last?
A well-maintained Wilson storage system typically lasts 10–15 years. If your system is nearing this age and developing faults, replacement is usually more cost-effective than ongoing repairs. We'll always give you an honest assessment.
Is my Wilson system still under warranty?
Warranty terms vary by model and purchase date — check your original paperwork or contact Wilson directly to confirm what's covered. Using a licensed plumber for all repairs and servicing is required to keep most manufacturer warranties valid. We use warranty-friendly diagnostics and genuine parts where possible, and can provide documentation if needed.

We're based in Kingsford and aim to reach most Eastern Suburbs locations within the hour. Emergency call-outs are available 24 hours a day, 7 days a week across Bondi, Randwick, Maroubra, Coogee and all surrounding suburbs.
