Aquamax stainless steel hot water: what it changes, and what it doesn't
A stainless steel tank is built to resist the internal corrosion that ends the life of many tanks. That's a real advantage. But it doesn't make the whole system immune to wear.
What stainless steel helps with: the tank itself tends to hold up well, which makes a single-part repair more likely to be worth doing.
What still wears out: thermostats, heating elements, burners and ignition parts, gas controls, relief valves and tempering valves. These are the usual reasons a storage system stops working, whatever the tank is made of.
What it can't prevent: a stainless tank can still leak eventually, and a tank leaking from the base usually can't be repaired.
So when your Aquamax stops working, don't write it off. Get it diagnosed first.
Signs your Aquamax needs a plumber
- The temperature won't hold steady: hot one minute, lukewarm the next.
- Slow to heat or running out of hot water sooner than usual.
- Water around the base or a wet cupboard floor.
- A constant drip from the relief valve drain pipe. See relief valve replacement.
- Unusual noises: rumbling, banging or hissing.
- Rising energy bills without a change in how you use hot water.
- Scalding or uneven water at the tap: often a tempering valve issue.
If water is leaking, switch off the power or gas to the unit and turn off the cold water valve before you call.

A word from an OnCall customer
"After countless refusals from other plumbers I managed to get hold of Aiden and he DID NOT DISAPPOINT … In the end he completely solved the issue and even cleaned afterwards."
Tim Dacey, café owner, Google review of OnCall Emergency Plumbers
Aquamax hot water service and maintenance
A well-built tank lasts longest when the parts around it are looked after. Regular servicing checks:
- Gas Aquamax units: burner, ignition and safety controls, on natural gas or bottled gas.
- Electric Aquamax units: heating elements and thermostats.
- All units: the relief valve and the temperature at the tap.
Catching a sticking valve or a tired thermostat early is cheaper than a callout on a cold morning. See hot water system servicing.
If your Aquamax is under warranty
If your Aquamax is still under the manufacturer's warranty, check with Aquamax first. Warranty repairs usually go through the manufacturer's own service network. Outside warranty, or when you can't wait, call us. We're an independent plumbing business that repairs and replaces Aquamax hot water systems.
Aquamax replacement in Melbourne
Replacement makes sense when the tank is leaking, the unit is past 10–15 years old, or several parts have failed at once. Because stainless tanks tend to hold up, a repair is often worth a look before you commit to a new unit, provided the numbers stack up.
When it is time, we'll talk through your hot water use, household size, available utilities and running costs. You might stay with a stainless steel storage tank, or decide another type suits you better. Then we safely disconnect and remove the old unit, install the new one, test every hot tap and commission the system. See hot water system replacement and hot water installation.
What an Aquamax repair costs
We charge by the job, not the hour. Your plumber diagnoses the system and gives you a clear price, with options, before anything starts. The price depends on the part, whether it's in stock, access and whether it's a repair or a replacement. See hot water repair cost.
Aquamax hot water questions
Do you repair Aquamax hot water systems?
Yes. We repair and replace Aquamax gas and electric storage systems across Melbourne. We're not an Aquamax service agent, so check with the manufacturer first for warranty work.
My Aquamax is stainless steel. Why is it leaking?
Leaks often come from a valve or fitting rather than the tank. We'll find the source. If it's the tank itself, replacement is usually the answer.
Is a stainless steel tank worth repairing?
Often, yes. If the tank is sound and one part has failed, a repair usually makes sense.
How long does an Aquamax last?
Most hot water systems last 8–15 years, depending on maintenance, water quality and use. A well-maintained stainless tank can sit at the longer end.
Can you come out tonight?
Yes. We're open 24/7, weekends and public holidays included, for urgent hot water jobs.
Can you fix it on the first visit?
Often, yes. Our plumbers arrive equipped for most jobs. If a specific part has to be ordered, we'll tell you the timeframe up front.
Aquamax not heating? Let's find out why.
Call us with the model and what it's doing. A licensed OnCall plumber will diagnose it, price it, and fix it once you're happy.
