How Corey Uncovered Hidden Damage and Delivered a Complete Hot Water Solution

The Situation

When Angus’s hot water system began showing signs of age, he knew it was time for a replacement. The unit had served its purpose for years, but declining performance and rising energy bills made it clear that putting off the job any longer would only lead to a complete breakdown at the worst possible moment. What Angus didn’t know was that behind the old heater, a previous installer had left behind a series of problems that would only become visible once the unit was removed.
The old water heater had been installed against an external wall of his Melbourne home. Over the years, the piping layout behind it had become a patchwork of shortcuts and makeshift connections rather than the clean, well-planned configuration you would expect from a professional installation. None of this was visible while the heater was in place. It was only when the old unit came down that the full picture emerged.
Angus was no stranger to Fix It Right Plumbing. He had called on the team before and had been impressed enough by the quality of work and the professionalism of the plumbers that he didn’t hesitate to call again. That kind of repeat business says something about a company, and in this case, it meant Angus had someone he trusted to handle whatever the job threw up.

Getting the Right Plumber on Site

Because Angus was already a returning customer, the booking process was straightforward. He contacted Fix It Right Plumbing directly, confident that the team would provide the same honest advice and professional service he had experienced previously. One of the advantages of working with an established plumbing company is that continuity of service. When a customer calls back, there is already a relationship in place, and the team can often match the right plumber to the job based on past experience.
In this case, Corey was assigned to the property. A senior plumber with extensive hands-on experience in hot water system installations, Corey had the skills and the temperament to handle what would turn out to be a far more involved job than a straightforward swap. From the initial phone call to arrival on site, the process was well-coordinated, with clear communication about scheduling and what to expect on the day.

What Corey Found Behind the Old Heater

The moment Corey began dismantling the old hot water system, the true scope of the job became apparent. Behind the unit, he discovered a large cavity in the external wall. The gap had been left by the tradespeople who had originally installed the heater years earlier. Rather than properly finishing the wall after running the necessary water and gas pipes through it, the previous installer had simply mounted the heater directly over the opening, effectively concealing the damage from view.
In addition to the wall cavity, Corey found that the piping layout was in poor shape. Pipes had been run in haphazard configurations, with connections that were technically functional but far from meeting current plumbing standards. Joints that should have been properly soldered were held together with temporary fittings. Pipe runs that should have been straight and supported were sagging and unsecured. It was the kind of work that might last a few years but would inevitably lead to leaks, water damage, or worse.
Corey took the time to document what he had found and explain the situation to Angus in straightforward terms. Rather than simply replacing the heater and leaving the underlying problems for someone else to discover, he recommended a comprehensive approach: replace the hot water system with a quality unit, realign all the pipework to proper standards, and repair the wall cavity with a durable, weather-resistant finish. Angus appreciated the transparency and gave Corey the go-ahead to complete the full scope of work.

How Corey Fixed It Right

With approval to proceed, Corey methodically worked through what had become a multi-faceted job. The first step was removing the old system completely and clearing the work area so he could assess every pipe, connection, and fitting behind where the unit had sat.
The replacement unit was an Aquamax, a trusted Australian brand with a strong reputation for reliability and energy efficiency. Aquamax gas storage systems are designed specifically for the Australian climate and come with comprehensive manufacturer warranties, making them a popular and practical choice for Melbourne homeowners. Corey positioned the new unit carefully, ensuring adequate clearance for ventilation and future maintenance access, both of which had been neglected in the previous installation.
Next came the pipework. Corey stripped out the old, poorly configured pipes and started fresh. He measured, cut, and fitted new copper pipes with properly soldered joints, running clean lines for both the hot and cold water connections. Each joint was tested for integrity, and every pipe was secured with appropriate brackets and supports. The gas connection was checked and certified to comply with current Energy Safe Victoria requirements. What had been a tangle of shortcuts was transformed into a neat, logical layout that any future plumber would be able to follow and maintain.
The wall cavity was the final challenge. Corey sourced a cement sheet panel that matched the external wall profile and cut it precisely to size. He secured it in place, sealed the edges, and finished it to a clean, professional standard. This was not just a cosmetic improvement. An exposed cavity in an external wall invites moisture ingress, pest entry, and heat loss, all of which can escalate into far more expensive problems if left unaddressed. By sealing it properly, Corey was protecting the home as well as the new hot water system.
The entire process took considerably longer than a standard hot water replacement, but Corey never once complained or tried to rush through the work. He treated the home with care, kept the work area tidy, and maintained a positive and professional attitude throughout the day.

The Result

By the time Corey packed up his tools, the property had been transformed. A brand-new Aquamax hot water system was installed to current Australian standards, the previously chaotic piping layout had been completely reorganised into a clean and logical configuration, and the unsightly wall cavity was sealed with a durable, professional-grade cement sheet finish.
The work was covered by Fix It Right Plumbing’s workmanship guarantee, in addition to the manufacturer’s warranty on the Aquamax unit. Before leaving, Corey walked Angus through the new system, explaining its operation, the temperature pressure relief valve, and what to look out for in terms of routine maintenance. He also pointed out the tempering valve, which limits hot water at bathroom taps to a maximum of 50°C as required under Victorian plumbing regulations, helping to prevent scalding.
Angus was so impressed with the quality of the work and the professionalism of the entire experience that he had no hesitation in recommending Fix It Right Plumbing to friends and family. For a tradesperson, that kind of endorsement from a repeat customer is the highest compliment there is.

What Melbourne Homeowners Should Know About Hot Water Replacements

Hot water systems are one of the most essential yet often overlooked components of a Melbourne home. Most systems have a lifespan of 8 to 15 years depending on the type, brand, and maintenance history. Understanding what to expect when the time comes for a replacement can help you avoid emergency situations and make a more informed choice.
Types of hot water systems available in Victoria:

• Gas storage — Heats and stores water in an insulated tank. Brands such as Rheem, Rinnai, and Aquamax offer models from 135 to 360 litres, suitable for households of all sizes.
• Gas continuous flow — Heats water on demand without a storage tank. More energy-efficient for smaller households and never runs out of hot water.
• Electric storage — Common in older Melbourne homes, especially where gas supply is unavailable. Reliable but generally less efficient than gas.
• Heat pump — Uses ambient air temperature to heat water. Highly efficient and eligible for Victorian government rebates under the Solar Homes Program.
• Solar with booster — Roof-mounted collectors with a gas or electric backup. Highest long-term savings but greater upfront investment.

When a hot water system is replaced, a thorough plumber will inspect the surrounding pipework, isolation valves, and connections as well as the unit itself. As Angus’s experience demonstrates, hidden problems can lurk behind a heater that has sat in the same spot for a decade or more. A quality installation includes verifying the temperature and pressure relief valve, confirming the overflow pipe is correctly routed to a safe discharge point, and ensuring all work complies with AS/NZS 3500, the Australian plumbing and drainage standard.
Under Victorian regulations, every hot water installation must include a tempering valve at bathroom outlets, limiting water temperature to a maximum of 50°C to reduce the risk of scalding. A licensed plumber will install and test this valve as a standard part of the replacement process.
