Aquamax Hot Water Repairs, Service and Installation in the Redlands and Brisbane Bayside
Aquamax units turn up on plenty of jobs around our own patch — Wellington Point, Ormiston and Thorneside — and DK Plumbing repairs, services and installs them across the Redlands and Brisbane bayside more broadly. We are an independent local plumbing business, not Aquamax, and we do not push one brand over another because of who we are affiliated with. If an Aquamax unit can be repaired sensibly, we tell you. If it cannot, we tell you that too.

Dave Kiddy is a licensed plumber and gas fitter with more than 20 years on the tools, based right here in Wellington Point, which means jobs in our own suburb and the immediately surrounding area often get our fastest response of anywhere we cover. He handles every Aquamax job from first call to finished invoice, so the quote and the work come from the same person.
The Aquamax hot water range in general terms
Aquamax is best known for continuous flow gas hot water units, which heat water on demand rather than storing it in a tank, and we see them fitted on the outside wall of homes right across the Redlands. Continuous flow suits households wanting an ongoing supply of hot water without the risk of running out, and it takes up far less space than a storage tank, which matters on smaller blocks and townhouse developments. Aquamax also offers storage electric and gas units for homes where continuous flow is not the right fit, whether because of gas supply, budget, or the layout of the property. As with any brand we work on, we are not going to claim Aquamax is the best choice on the market — the right unit comes down to your household's hot water use and how the home is set up, not brand loyalty.
Common faults we see on Aquamax units
The most frequent call we get on Aquamax units is no hot water, which on a continuous flow system can point to an ignition fault, a problem with gas supply to the unit, or an issue with the flow sensor that tells the unit water is being drawn. Ignition and pilot issues are common after a gas bottle swap or a power interruption, since continuous flow units rely on both gas and electricity to fire correctly. Continuous flow units display an error code when something is wrong, and the exact meaning varies by model and firmware version, so we always read the code on the unit itself rather than diagnosing over the phone. On the smaller number of Aquamax storage tanks we service, we see the usual TPR valve leaks and, on older steel tanks near the water in Wellington Point and Ormiston, corrosion brought on by salt air. Blocked or corroded external flues on wall-mounted units are also worth checking, particularly on homes that back onto trees or dense gardens.
Repair or replace
Whether we repair or recommend replacing an Aquamax unit depends on the fault, the age of the unit and whether parts are readily available for the model. Where replacement makes more sense, most residential hot water replacements run $1,200 to $3,000 supplied and installed. If your Aquamax unit has failed and hot water has stopped altogether, most emergency callouts run $250 to $600 depending on what needs doing. We confirm the number with you before any work begins.
We also install and service other brands
Aquamax is one of six brands we work on across the Redlands and bayside. DK Plumbing also repairs, services and installs Rheem, Rinnai, Dux, Vulcan and Bosch hot water systems, so if you are weighing up a replacement, we can talk through what suits your home rather than assuming a like-for-like swap is best.

Brands we service
We repair, service and install every major hot water brand. We are an independent local plumber, not a manufacturer.
Common questions
Do you use genuine parts?
We fit parts suitable for the unit, and genuine parts where that is required to keep a manufacturer warranty in place. We will confirm which situation applies before we begin.
Is my Aquamax unit still under warranty?
Check your paperwork or the details on the unit itself — warranty terms vary by model and installation date. If you are unsure, we can help you work it out once we have looked at the unit.
What does an error code on my Aquamax unit actually mean?
It depends on the model and firmware, so we read the code from the unit on site and confirm the fault before quoting, rather than guessing based on the code number alone.
Can you service a continuous flow unit before it fails, not just repair it after?
Yes. A regular service, including checking the gas connection, flue and flow sensor, picks up small issues before they turn into a no-hot-water emergency.
Do you cover Wellington Point and the suburbs right around it?
Yes, and given this is our home base, jobs here and in Ormiston and Thorneside are often where we can get to fastest.
