Dux Hot Water Repairs, Service and Installation in the Redlands and Brisbane Bayside

Dux is a brand we run into regularly on older homes across Alexandra Hills, Birkdale and the wider Redlands, and DK Plumbing repairs, services and installs Dux hot water units as part of our everyday work. We are not Dux, and we do not have any commercial tie to the manufacturer — we are a local, independent plumbing business that happens to see a lot of Dux units because they have been fitted in this area for a long time.

A spirit level sitting on top of a hot water storage tank during installation

Dave Kiddy is a licensed plumber and gas fitter with more than two decades of experience, and he handles every Dux job himself, from a first look at a tank that has stopped working through to a full replacement. Because he quotes and does the work, you are not dealing with an office estimating over the phone without seeing the unit.

The Dux hot water range in general terms

Dux has been part of the Australian hot water market for a long time, and units from this brand turn up most often as storage systems — electric storage tanks in older homes where the unit sits quietly heating water off-peak, and gas storage units where a faster recovery time suits a bigger household. In more recent years Dux has also offered continuous flow gas units for homes wanting an on-demand supply without a tank taking up space in the laundry or under the house. Because of how many older Dux units are still in service around the Redlands, a large part of our work with this brand is on ageing storage tanks rather than new installs, though we install new Dux systems as well where that is the right fit. As with every brand we work on, we are not going to tell you Dux is better or worse than the alternatives — the right unit depends on the home, not the badge on the front.

Common faults we see on Dux units

Because so many Dux units in the Redlands are older storage tanks, the faults we see reflect that age. No hot water is the most common call, and on an electric unit that usually traces back to a faulty element or thermostat, while on a gas unit it is more often a pilot light or ignition fault, particularly if the unit has been sitting unused. A leaking TPR valve is another regular job on older Dux tanks — sometimes a simple valve swap, sometimes an early sign that the tank itself is under more pressure than it should be. Tank corrosion is a genuine issue on older steel storage units this close to the bay, and we see it often in Alexandra Hills and Birkdale on units that have quietly been corroding from the inside for years before a leak appears. On newer Dux continuous flow units, faults tend to show up as an error code on the display, and the meaning of that code depends on the model, so we always check it against the unit rather than assuming.

Repair or replace

For an older Dux tank, the decision often comes down to whether the tank itself has started to corrode, in which case a repair is only a short-term fix. Either way, we tell you the number before we start.

We also install and service other brands

Dux is one of six brands we work on regularly. DK Plumbing also repairs, services and installs Rheem, Rinnai, Vulcan, Aquamax and Bosch units, so if an older Dux tank needs replacing, we can talk through what suits your home rather than defaulting to a like-for-like swap.

Common questions

Do you use genuine parts?

We fit parts suitable for the unit, and genuine parts where that is needed to keep a manufacturer warranty valid. We will let you know which applies before the work starts.

Is my Dux unit still under warranty?

Check your paperwork or the sticker on the unit — warranty periods have varied over the years depending on model and when it was installed. If you cannot find the details, we can help you work out where you stand.

My Dux tank is old — is it worth repairing?

Often it comes down to whether the tank itself is corroded. If the tank is sound, a repair usually makes sense. If it is not, we will tell you plainly rather than patching a unit that will fail again soon.

Can you replace an old Dux tank with a different type of unit?

Yes. If a continuous flow or heat pump system would suit your household better than a like-for-like tank replacement, we will explain the options on site.

How quickly can you attend a no hot water emergency?

Same-day response is standard, and for a genuine emergency, such as no hot water across the whole house, we aim to be on site within a couple of hours.

"I called DK Plumbing on Thursday morning. They arrived 1 hour later. Fixed every problem i had. Taps washers there was many. Absolutely would recommend Dennis and his trusty apprentice Jesse. Did a great job ."
Karen Kuzewicz
"Though our job was relatively small, that did not mean that it got pushed down the priority list for Dave. He was able to come out and fix our broken downpipe in super fast time and even provide some sound advice to prevent similar problems in the future. Thanks DK, Dave and Jesse."
