Common signs your hot water system may be failing
Erratic hot water temperature
One of the most obvious signs your water heater is experiencing issues is inconsistent or fluctuating hot water temperatures. If you’re grappling with unusually hot or cold water, or dramatic temperature shifts even during the same shower, it begs the question, what do these changes imply? They likely mean the thermostat, heating elements or other components are breaking down.
Strange sounds
Unusual noises like banging, rumbling, or hissing may be harbingers of low water conditions in your system. Sounds may indicate sediment build up, a faulty heating element or other problems. Take note of any new, unusual sounds from the water system.
Inspect your tank diligently to find out if there are any small drips or puddles around your water heater. Promptly addressing leaks can avert significant water damage.
Low hot water pressure
Diminished water pressure, especially when paired with irregular hot water, can suggest the onset of low water pressure within your unit. Ensure valves are in working order and seek expert advice if water pressure issues continue.
Fluctuating or insufficient hot water supply
Inconsistent or insufficient hot water is a frustrating issue that often means your hot water system is failing in some way. A lack hot water supply consistency can be due to issues with the thermostat or heating element inside your hot water system.
Try these troubleshooting tips:
- Check your hot water system’s thermostat to make sure it is set correctly and hasn’t been accidentally changed. Ensure it is set to at least 60°C.
- Examine the heating element by turning off the power and checking for signs of heating before removing it for inspection.
- To ensure consistent hot water delivery, verify all valves are open, and consider what might be troubling your hot water system about its performance.
- Inspect your pressure relief valve for faults or blockages.
After attempting these measures, if hot water still remains elusive, it’d be wise to call your trusted plumber for a thorough inspection.

Leaking water
One of the most worrying indicators of your heating system’s decline is a visible water leak. Small leaks or dripping around your hot water tank can cause major flooding and water damage if left unchecked.
Inspect around the full perimeter of your hot water heater, including valves, joints and connections, for any droplets, puddles or moisture. You can also inspect along the water pipes leading in and out for evidence of your heater leaking. Small leaks from hairline tank cracks or loose fittings could be a sign there’s a deeper issue, like a faulty relief valve.
It’s crucial to identify and repair any water service leaks as soon as possible. The initial crack, if ignored, could due to expansion lead to complete water heater failure over time. This accelerates risks of your water heater going out and can lead to complete system failure if severe enough.
If you spot any form of leak, shut off the water supply to your hot water unit right away. Then call 1300 349 338 or email us to book an urgent plumbing appointment with our leak detection and hot water specialists at Penrith Plumbing.
Discolored or dirty water
Rust, corrosion, and mineral accumulation within your system’s tank and pipes can cause discoloured or dirty hot water that can affect your home’s water quality. As components corrode over time, flaking metal and sediment can discolour the water supply.
Try operating all hot water taps on full for 5-10 minutes to flush the water coming from the build-up from the bottom of the tank and through the pipes. If the water remains discoloured or dirty, it may be time to consider replacing your hot water system.
Contaminated hot water with unpleasant odours can pose health hazards for consumption and bathing. Sediment and foreign particles can lead to more extensive problems, such as clogged pipes and valves. It’s crucial to address dirty hot water right away.
If discoloured water persists after flushing, our experts can examine your hot water system and its components. We can advise whether your system needs repair or replacement.
Unusual noises from the system
Hearing new sounds like rumbling or banging from your hot water system can be distressing signs of failing water heater components.
Try draining your hot water tank completely, then refilling it to flush out any sediment buildup and prepare for new hot water. Annual draining of the heater tank is essential for maintaining efficient hot water delivery.
If persistent noises remain even after flushing, it might be a heater failure, necessitating professional assessment.

High energy bills
A spike in energy bills, particularly if your system is more than 10 years old, could be a sign your water heater’s efficiency is declining.
As systems age, components can wear out, leading to inefficiencies and increased energy usage due to the heater working harder. This increased effort uses more energy, hiking your energy bills.
Take note if your bills increase by 15% or more, especially if it could be due to an inefficient hot water system about to fail. Compare the rise to the same billing period last year.
It’s advisable to have your system professionally assessed when your hot water system reaches 8-12 years even without other issues to check for efficiency. Exorbitant energy bills may indicate the need for a modern, more energy-efficient hot water system.

Troubleshooting tips for common hot water system problems
No hot water
If you have no hot water, If there is no hot water, verify that the power and gas supply are switched on at both the mains and the hot water system.
Ensure your gas pilot light is active if you’re operating a gas hot water system. For gas water heaters, it’s worth attempting a reset of temperature or pressure relief valves before checking other electrical issues. Drain and flush sediment if needed. If basic troubleshooting steps fail, it’s time to speak to our specialists about your water heater’s health for repair or replacement advice.
Leaking water
Immediately turn off water supply to the system then inspect joints, valves and pipes closely to locate the leak source. Check for hairline cracks in the tank. A seemingly insignificant leak in your system can escalate quickly, warranting immediate attention to prevent a leak your water service might face.
Strange noises
If you hear unusual rumbling or banging, this might reveal sediment leading to a potential leak in your hot water system. If noises continue post-flushing, get in touch as your system likely needs repairing.
Poor hot water pressure
To isolate any issue, full opening of all isolation taps is necessary, and do check water pressure elsewhere, perhaps in the shower, to understand your heater’s performance. To ensure the ideal pressure your temperature and relief valves may require an inspection or replacement if they’re faulty. Persistent low pressure suggests an internal system failing, requiring a plumber’s assessment.

Options for replacing your failing hot water system
If you’ve determined your hot water system needs replacing, you have several replacement options to evaluate:
Storage tank water heaters
Storage tank heaters are a popular type of hot water system, consistently chosen for their reliability. These have a tank which heats and stores gas hot water until needed. Choose from gas, electric, or your gas electric hot water systems for optimal energy efficiency and savings.
Tankless water heaters
Tankless units supply water heated on demand, ensuring you are free from worries about depleting a stored supply. Often wall-mounted, these suit smaller households with 1 or 2 bathrooms to avoid flow limitations.
Solar hot water
Harness the sun’s renewable energy for some/all of your hot water heating. Solar systems need roof space and a gas or electric booster to effectively heat water while reducing bills.
Heat pump
Electric water heaters with heat pump technology utilise ambient heat to keep your water hot all day with superb efficiency. They still need a storage tank and suit warmer climates best.
Choosing the right replacement system for your home’s needs and budget is crucial long-term. Contact our team on 1300 349 338 to discuss your options or request a quote online.
