When your hot water stops working, the first question is simple: can it be fixed, or does it need replacing? Our job is to answer that honestly. We assess the system onsite, find the actual cause of the fault, and give you clear pricing before anything is touched. If a repair will genuinely last, we repair. If the system is on its way out, we'll tell you that too — and why.
Common hot water faults we repair
No hot water at all
For electric systems this is usually a failed heating element or thermostat — or a tripped breaker. For gas systems, it's commonly the pilot light, thermocouple or gas valve. All are straightforward repairs with parts we carry.
Water not hot enough, or running out fast
Often a thermostat issue, a failing element (on twin-element systems), or sediment buildup from Perth's mineral-heavy water reducing the tank's effective capacity. Sometimes it's simply a system that's undersized for the household — we'll tell you honestly which it is.
Leaks
Leaks from valves, fittings and pipe connections are usually repairable. A leak from the tank cylinder itself means the glass lining and steel have corroded through — that's not repairable, and the system needs replacement. We'll show you exactly where the leak is so you can see it yourself.
Strange noises
Rumbling, popping or banging is typically sediment baking onto the bottom of the tank. Left alone it destroys efficiency and shortens the system's life. Caught early, a flush and service can buy years.
Tempering valve & pressure valve issues
Faulty tempering valves cause lukewarm or fluctuating water temperature. Faulty pressure relief valves drip constantly or fail dangerously. Both are quick, inexpensive replacements that keep your system safe and compliant.
How a repair visit works
- Clear booking window — you know when we're arriving, with an ETA update on the way
- Proper diagnosis — we find the cause, not just the symptom
- Upfront price — you approve the repair cost before we start
- Fixed on the spot where possible — our vans carry common parts for Rheem, Rinnai, Dux, Bosch and Vulcan systems
- Straight advice — if the system is nearing end of life, we'll say so and quote both options
Repair or replace?
The honest rule of thumb: systems under 8 years old with a single failed component are usually worth repairing. Systems over 10 years old, leaking from the tank, or needing their second major repair are usually better replaced. Either way, you get both prices in writing and the decision is yours — no pressure either way.
Brands we repair
Rheem, Rinnai, Dux, Bosch, Vulcan, Aquamax and most other brands installed in Perth homes — gas, electric, solar and heat pump. See also: which brands we rate for Perth conditions.
Frequently asked questions
Why is my hot water system not producing hot water?
Most often a failed element or thermostat (electric), a pilot or gas valve fault (gas), or a tripped breaker. We diagnose the exact cause onsite, usually in one visit.
How much does a hot water repair cost in Perth?
Most single-component repairs cost a few hundred dollars including parts and labour. You approve the price before work begins. See our full cost guide.
Can a leaking hot water system be repaired?
Valve and fitting leaks, yes. A leak from the tank cylinder itself means internal corrosion — that requires replacement.
Do you repair all brands?
Yes — Rheem, Rinnai, Dux, Bosch, Vulcan, Aquamax and more, across gas, electric, solar and heat pump.
