I just had a repair done by Kaleb and Vas and I was very impressed. We woke up with no hot water this morning and called Curl Curl Plumbing for help. The boys came out the same day and fixed the issue. They kept me informed with every step of the process and I'm very relieved to say, everything is fixed and will be having hot showers again, which is a relief!

Yes, as part of our comprehensive service, we remove and responsibly dispose of your old hot water system—completely free of charge. Our goal is to make the installation of your new hot water unit as smooth and stress-free as possible, leaving your property clean and tidy.

You won't have to worry about handling heavy tanks or organising disposal yourself; we take care of everything from start to finish.

We supply and install Australia's leading hot water brands, including Rheem, Rinnai, Bosch, Dux, Aquamax, and Thermann. Our plumbers carefully select brands known for reliability, efficiency, and durability, ensuring you receive a high-quality system tailored specifically to your needs and budget.

If you're unsure which brand or model is best for your home or business, our experts will gladly provide personalised advice to help you make an informed decision.

Strange tastes or odours in your hot water usually indicate a build-up of minerals, sediment, or bacteria inside your hot water system. Common causes include corrosion in old tanks, bacterial growth, or issues with your water supply.

We recommend having your hot water system inspected promptly if you notice unusual tastes or smells. Our plumbers will identify the issue and offer practical solutions, whether it's flushing the tank, replacing internal components, or installing a filtration system to ensure safe, clean-tasting hot water.

If your water heater is leaking, it's important to act quickly to minimise water damage. First, turn off the water supply to the heater, typically located near the top or bottom of the unit. Then, switch off the power supply—electricity or gas—to prevent further hazards.

Contact us immediately, and our plumbers will guide you through any additional steps over the phone. We'll arrange a rapid repair or replacement, ensuring your hot water service is restored safely and efficiently.

We prioritise hot water system repairs and can usually restore your hot water supply the same day. If you contact us early, we aim to have a plumber at your property within hours. Our fully stocked vehicles carry a wide range of parts, allowing us to fix most problems immediately.

Even after hours and on weekends, our team is available to quickly handle urgent hot water emergencies, ensuring minimal disruption to your home or business.

There are a few common signs that suggest your hot water system may need attention:

  • The system is over 10 years old, which makes it more prone to wear and inefficiency.
  • Discoloured or rusty water, which often indicates corrosion inside the tank.
  • Visible water leaks around the tank, a clear sign of structural issues leading to possible damage.
  • Inconsistent water temperature, such as water that is too hot, too cold, or fluctuates frequently.

If you notice any of these issues, it's best to address them quickly. Our team of specialists can inspect, diagnose, and resolve the problem - whether through repairs or a same-day replacement.

Electric Hot Water Systems: These systems are reliable, affordable to install, and easy to maintain. However, they typically come with higher running costs, especially if your usage is high.

Gas Hot Water Systems: Gas systems offer excellent energy efficiency, rapid heating times, and generally lower ongoing costs compared to electric units. The drawbacks include the need for a natural gas connection and regular servicing to maintain efficiency and safety.

Solar Hot Water Systems: Solar systems are environmentally friendly and significantly reduce energy bills by harnessing free solar energy. While the initial installation cost is higher, they often pay for themselves through substantial long-term savings. However, their efficiency depends on sufficient sunlight, and they typically require a backup energy source for cloudy days.

Heat Pump Hot Water Systems: Heat pumps are highly efficient, offering substantial reductions in running costs compared to traditional electric units. Although they involve a higher initial investment, they're cost-effective in the long run. Heat pumps do require adequate outdoor space and operate best in mild to warm climates.

If you're unsure which system suits your home or business best, our plumbers can provide personalised advice tailored specifically to your needs and budget.
