Metro Electrical 24 Hour Electricians have been a delight to deal with from the moment i called for an intial quote to look at an oven that was tripping up the electricity. Their advise has been great and have used them several times after the initial service. Their prices are very competetive, they are professional and also clean up after themselves, which is small matter but shows the level of effort they put in every job. I would highly recommend them.

Signs Your Hot Water System Needs Repair

Recognising when your hot water system requires professional attention is essential to maintain its efficiency and prevent potential damage to your home. Metro Electrical, with its team of experienced professionals, can assist in diagnosing and repairing any issues your system may face. Here are key signs indicating that your hot water system needs repair:

Lack of Hot Water
One of the most apparent signs of a malfunctioning hot water system is an insufficient supply of hot water. This could be due to various reasons, including a tripped fuse, a faulty heating element, or sediment buildup in the tank, which affects the system’s ability to heat water efficiently. If you find yourself frequently running out of hot water or experiencing a complete lack of hot water, it’s time to consult with a specialist from Metro Electrical.
Unusual Noises
Strange noises emanating from your hot water system can indicate underlying issues that require immediate attention. Sounds such as banging, rumbling, or popping are often caused by pressure issue like over heating. Sediment can cause the heating element to overwork, leading to these alarming noises. Regular maintenance, including flushing the tank to remove sediment, can prevent these sounds and prolong the life of your system.
Rusty or Cloudy Water
If the water from your hot taps appears rusty or cloudy, it could signify corrosion within your hot water system. This issue often arises from the sacrificial anode rod wearing out, which leads to the tank rusting from the inside. Discoloured water can also result from sediment buildup, further indicating the need for system maintenance or repair.
Leaking or Dripping
Water leaks from your hot water system should never be ignored, as they can lead to significant water damage over time. Leaks can stem from various sources, including the pressure relief valve, loose pipe fittings, or even cracks in the tank itself due to corrosion or high water pressure. Monitoring the amount and frequency of leaking water can help determine the severity of the issue. A constant stream of dripping water or large amounts of water leaking from the system indicates a serious problem like a thermostat failure causing a over heating and pressure issue that requires immediate intervention by Metro Electrical’s skilled technicians.
By staying vigilant and recognising these signs, you can ensure the longevity and efficiency of your hot water system. Regular maintenance and timely repairs by Metro Electrical can prevent minor issues from escalating into major ones, saving you time and money in the long run.

Common Hot Water System Problems

Thermostat and Element Issues
One of the primary reasons your hot water system may not perform optimally is due to thermostat and element issues. If you’re experiencing inconsistent hot water or a complete lack of it, the problem could stem from a faulty upper element or thermostat. This is particularly true if hot water runs out quickly, indicating a defective lower element or thermostat. Testing the elements with an Ohm-meter can help diagnose the issue. A reading of about 100 ohms or higher suggests a functional element, while no movement on the meter indicates a malfunction. It’s also worth noting that thermostats tend to fail more frequently than heating elements. Therefore, checking the thermostats should be a priority, and replacing them, even if they test good, can be a prudent step if you’re also changing the elements.
Tempering Valve Malfunctions
Tempering valves play a crucial role in ensuring the water from your hot water system is at a safe temperature, preventing scalding. However, when these valves malfunction, you might experience water that is either too hot or too cold. A defective thermostatic mixing valve could be the culprit, failing to adequately cool down hot water or, conversely, not heating the water enough. Other signs of a tempering valve issue include inconsistent water flow, visible water leaks indicating a faulty seal or corrosion, and fluctuations in water temperature. Regular checks and maintenance are recommended to avoid these problems, and in case of malfunction.
Calcium Build-Up and Sediment Issues
Over time, calcium and other mineral sediments can accumulate in your hot water system, leading to a series of problems. This build-up can significantly reduce the efficiency of your system, increase energy consumption, and potentially shorten the lifespan of the unit. Calcium and magnesium, found naturally in water, are the primary culprits behind this sediment accumulation. They can settle at the bottom of the tank, hindering heat transfer and causing corrosion, decreased tank capacity, and blockages in water lines. Regular flushing of the hot water system is essential to prevent sediment build-up. Additionally, installing a water softener can mitigate the problem by reducing the mineral content in the water, thus prolonging the life of your hot water system.
Each of these common problems can significantly impact the performance and longevity of your hot water system. Regular maintenance and timely repairs by a trusted service provider like Metro Electrical can help ensure your system operates efficiently and reliably.

DIY vs Professional Repairs

Risks of DIY Repairs
Attempting to repair your hot water system on your own may seem like a cost-effective solution, but it comes with significant risks and even fines. DIY water heater repairs can lead to potential hazards, including the risk of electrocution, which is just one of many dangers that may arise from such undertakings. These repairs often involve handling hazardous chemicals used in water heaters, which, if not managed properly, can cause severe health issues or even death, as well as contribute to environmental pollution. Furthermore, working on gas lines or electrical components without proper knowledge can result in gas leaks or fire hazards. The complexity of these systems means that a mistake could cause damage beyond repair, leading to more significant expenses than initially anticipated. DIY repairs also risk voiding manufacturer warranties, leaving you financially responsible for any further repairs or replacements needed due to improper handling.
Benefits of Hiring a Professional
In contrast, hiring a professional, such as Metro Electrical, for your hot water system repairs offers numerous advantages. Professionals have the knowledge, training, and experience to provide cost-effective advice, including whether to repair or replace your hot water system. They are familiar with all regulations and codes, ensuring that any installations or repairs are compliant and avoid legal issues in the future. Professional repairers minimise disruption to your daily routine and consider factors such as home size, number of occupants, and hot water usage patterns to maximise energy efficiency. They possess the right tools and replacement parts for a smooth and efficient repair process and offer workmanship guarantees, honouring the warranty on your hot water system for long-term peace of mind. Additionally, professionals carry full public liability insurance, providing an extra layer of protection in the rare case that something goes wrong during the repair process.
Opting for professional repairs ensures that your hot water system is fixed safely and effectively, protecting you, your property, and your investment in the long run.

Simple fixes such as replacing a broken heating element, resetting a tripped circuit breaker, or replacing a thermostat are usually quick and cost-effective. For more complex issues, such as sediment buildup or a corroded anode rod, more involved repair methods are necessary. These may include flushing the system to remove sediment or replacing the anode rod to prevent further corrosion. Metro Electrical utilises the latest tools and techniques to ensure repairs are done effectively, minimising the chance of future breakdowns.
Replacement vs Repair Decisions
Deciding whether to repair or replace a hot water system is a critical part of the process. This decision is influenced by several factors, including the cost of repairs relative to the price of a new system and the age of the current unit. If the repair costs exceed half the price of a new system, or if the unit is old and out of warranty, replacement may be the more cost-effective option. Metro Electrical provides expert guidance to help you make this decision, considering factors such as energy efficiency, system size, and your household’s hot water needs.

Maintenance Tips to Extend the Life of Your Hot Water System

Just like any significant appliance in your home, your electric hot water systems demands regular attention to perform at its best. By adhering to a few key maintenance practices, you can significantly extend the lifespan of your unit, ensuring it provides reliable service while also keeping your energy bills in check. Metro Electrical, with its team of experienced professionals, emphasises the importance of regular inspections, system flushing, and anode replacement as essential steps in hot water system maintenance.
Regular Inspections
It’s recommended to visually inspect your hot water system at least every six to twelve months. This routine check should include looking for any leaks at the tank, valves, and plumbing connections. Additionally, lifting the relief valve to release excess pressure and hot water periodically can help prevent potential issues before they escalate. For comprehensive care, a major service by a licensed professional every five years is advised, which may be necessary for warranty claims. This service should inspect the condition of the anode rod, especially in non-stainless steel tanks, to prevent internal corrosion.
Flushing the System
Flushing your water heater is crucial for removing sediment buildup, which, if ignored, can impair your system’s efficiency and lead to premature failure. The process involves turning off the system and water supply, attaching a hose to the drain valve, and allowing the water to flush out the sediment. This simple yet effective procedure should be performed annually to prevent sediment from calcifying and damaging the unit. Remember, even if your unit appears to be functioning correctly, an annual plumbing inspection is recommended as a preventative measure to avoid the cost of replacing the entire unit.
Replacing Anodes
The anode rod, or sacrificial anode, is a critical component designed to protect your hot water system from rust and corrosion. Made from magnesium, aluminium, or zinc, this rod undergoes sacrificial electrochemical action to protect the steel tank. Anodes should be inspected every 3 to 4 years, or more frequently in areas with bad water quality or if using softened water. Signs that an anode needs replacement include significant deterioration, exposure of the steel core, or the rod being coated with calcium carbonate. Replacing an anode is a cost-effective way to prevent costly repairs or the need for a new hot water system.

By following these maintenance tips, including regular inspections, system flushing, and timely replacement of anodes, you can ensure the longevity and efficiency of your hot water system.
