Hot water problems? Call Cheapa Hot Water Western Suburbs.

From cold showers to strange noises and inconsistent water temperature, we’ve seen it all. Understanding common hot water system problems can help you avoid unnecessary stress and costly replacements.

Below, we’ve outlined the most frequent issues and how they can be resolved.

NO HOT WATER

If your hot water has stopped completely, it’s likely an issue with the heating element or thermostat. These components can usually be replaced quickly and affordably by a professional.

For gas hot water systems, check whether the pilot light is out. If it is, you can try relighting it according to the manufacturer’s instructions. If the pilot light won’t stay lit, the thermocouple may need replacing—contact us for assistance.

RUNNING OUT OF HOT WATER

If you’re regularly running out of hot water, it could be due to increased household demand, such as a growing family. Upgrading to a larger, energy-efficient storage tank can resolve this issue and may even reduce running costs.

Other causes include:

  • Malfunctioning Thermostat: Ensure it’s set to the recommended 49°C.
  • Broken dip tube: A damaged dip tube can cause cold water to mix with hot, reducing overall temperature.
  • Sediment build-up: Over time, sediment accumulates at the bottom of the tank, reducing efficiency. Flushing the tank can help restore performance.

LUKEWARM WATER OR SLOW REHEATING

If your water temperature is inconsistent or it takes too long to reheat, the tank size may be too small for your household needs, or your system may need repairs.

Common causes include:

  • A faulty tempering valve or heating element.
  • Sediment build-up, reducing the efficiency of the system.

WATER HEATER MAKING STRANGE NOISES

Banging, popping, or rumbling noises usually indicate an issue with your water heater. While some noise is normal during operation, unusual or increasingly loud sounds may signal:

  • Sediment build-up: Causes popping sounds as water heats through the debris.
  • Expanding parts: Metal components may expand or contract during heating, leading to banging noises.

LEAKING WATER HEATER

Water pooling around your heater is a sign of a leak. Depending on the cause, the fix may range from tightening fittings to replacing components.

Common causes of leaks include:

  • Corrosion in the tank.
  • Loose or damaged pipes and connections.
  • Malfunctioning pressure relief valves.
  • Sediment build-up causing cracks or damage.

DISCOLOURED OR SMELLY HOT WATER

Yellow, rusty water or a metallic/rotten egg smell often indicates corrosion inside the tank or bacterial growth.

The anode rod inside your water heater plays a crucial role in preventing rust. Over time, these rods corrode and need replacing, typically every 3 to 5 years. Replacing the anode regularly can extend your water heater’s life and prevent costly repairs.

If your water heater is over 3.5 years old, call us with your system’s make and model to determine whether an anode replacement is needed.
