While uncommon, hot water systems can potentially explode due to a build up of pressure. This is often caused by faulty valves or lack of maintenance. Have your hot water system serviced regularly to help prevent excessive pressure build up and reduce risk.
Hot water systems are indispensable in homes and businesses across Australia. These systems provide hot water for showers, laundry, dishwashing, and sanitation requirements. Yet, neglecting maintenance can lead to hot water system explosions, endangering safety.
Although uncommon, hot water systems can explode under certain conditions.
Explosions in electric hot water systems often result from excessive pressure and temperature within the tank. A malfunctioning pressure relief valve can fail to reduce this pressure, potentially causing the tank to rupture. Such a pressure buildup can lead to catastrophic outcomes, such as system explosions that cause significant damage, injuries, or even fatalities.
As plumbing experts specialised in hot water system installations and maintenance, we emphasise the importance of identifying and managing risk factors to prevent explosions. By proactively servicing and educating on preventive measures, our objective is to maintain the safety and comfort of on-demand hot water in your home.
Various pressure and temperature factors can contribute to potential hot water system disasters:
Malfunctioning TP Valves are a prevalent cause for concern. Designed as safety features, these valves are meant to open and release any excess pressure from within the tank. If the temperature pressure relief valves are compromised due to age, defects, or improper installation, pressure may continue to rise, creating a hazardous scenario.
A combination of high pressure and temperature could endanger your water heater, as it may exceed safety limits and risk an explosion. Thermostats connected to your hot water tank may fail to shut off the heating elements at the proper temperature.
Sediment buildup on heating elements can cause excessive heat, leading to concerns about your water heater’s safety. Similarly, a faulty thermostat that permits uncontrolled temperature rise could trigger an explosion.
Over time, corrosion and mineral deposits can accumulate inside the tank, leading to increased risk.
Improper installation, particularly misaligning the TP valve without the correct safety measures, can lead to malfunction or even explosion. Incorrectly fitted pressure relief valves, pipes, or other components can compromise the integrity and safety of your water heater, leading to the risk of an explosion. Lack of regular professional maintenance also heightens risks as problems go undetected.
Understanding the causes of system explosions enables homeowners to take preventive action by ensuring proper installation and maintenance of the TP valve, enhancing home safety. If in doubt, seek inspection and servicing from licensed professionals.
Sediment buildup inside your hot water tank over time can greatly increase the risk of dangerous overheating and explosions. Sediment refers to mineral deposits and rust particles that accumulate at the bottom of your water heater tank.
Statistics show that without regular maintenance, especially sediment management, as many as 75% of hot water systems five years and older are at risk of unexpected failure. As the sediment layer thickens, it causes a number of problems:
To prevent sediment buildup and maintain a clean water system, it is recommended to have your water heater professionally flushed annually. This drains out the loose sediment before it can cause serious issues. Flushing only takes about an hour and is a small price to pay for the added safety and longevity it provides your system.
During a flush, a technician will check the discharge pipe and inspect, and if necessary, replace the corroded anode rod. The anode rod attracts corrosion away from the tank itself. Replacing the anode rod every 5 years greatly reduces the risk of corrosion, thus minimizing the chances of leaks and system explosions.
Don’t ignore yearly flushing and anode rod maintenance if you aim to keep your water heater from malfunctions and ensure safe and efficient operation throughout its lifespan. Catching problems early not only prevents sediment buildup issues but also avoids far more expensive repairs down the track.
Gas leaks pose a serious danger and can potentially lead to fires or explosions if not addressed promptly. In gas heaters, neglected pilot lights or broken thermocouples, often due to faulty installation, can result in undetected gas escape over time.
Warning signs of a gas leak include the smell of rotten eggs or sulphur near your water heater. You may also hear a hissing noise if the leak is substantial. Should you suspect a leak, survey the area, exit promptly, and contact our emergency plumbing services.
Never attempt to find or repair a gas leak on your own. As a precaution, cut the gas supply and increase ventilation by opening windows. Ultimately, the safest approach is to leave gas lines in the hands of qualified professionals.
At Mortdale Plumbing, all of our plumbers are fully licenced and experienced with gas line repairs, installations, and maintenance.
If pressure builds up too high, the tank can experience immense strain on its metal walls and seams. The pressure relief valve, also designed for pressure release and to reduce pressure, is a safety mechanism intended to prevent conditions where a tank can explode.
A faulty TP valve that fails to open can cause pressure to dangerously accumulate with no release inside the tank. Excessive pressure can force the metal walls to expand beyond their limits, leading to a rupture and potential explosion. Proper installation and regular valve testing helps avoid this risk.
If you notice any of these signs, shut off the gas or power supply to your hot water system right away. Then call a professional plumber immediately to inspect your system and make any necessary repairs.
A leaking pressure relief valve on your hot water system is a serious issue that requires immediate attention. This valve is a critical safety component designed to release excess pressure from inside the tank before it reaches dangerous levels. A leaking pressure relief valve on your hot water system is a serious issue that requires immediate attention.
Left unaddressed, a leaking relief valve can eventually lead to a full-blown tank explosion. As pressure climbs inside the stressed metal tank, it will eventually rupture violently. In addition to this explosion risk, a leaking valve also causes water damage over time.
Conducting an annual check where you assess for signs that can indicate issues with your water heater’s pressure relief valve is critical. Water should flow out when opened, then stop when you release the lever. If water continues dripping, the valve needs replacement by a professional plumber.
Our team at Mortdale Plumbing can provide and fit a new pressure relief valve for your hot water system. We ensure that the pressure relief valve TP is accurately matched to your tank’s dimensions and pressure requirements. We also offer affordable yearly maintenance plans with included valve inspections for peace of mind.
Do not compromise your home’s safety and risk endangering your family by delaying the repair of a leaking pressure relief valve. Contact us today to schedule an inspection or replacement and ensure your hot water system remains in safe working order.
If you hear consistent popping or cracking noises coming from your hot water system, this is a telltale warning sign that pressure levels are dangerously high inside the tank. The popping occurs when pressure repeatedly forces the metal walls of the tank to expand slightly and then contract.
The metal and seams of the water heater tank can weaken under the prolonged strain of pressure and temperature changes. The popping noises indicate the tank is under immense strain and pressure continues building.
Unchecked, this could lead to a violent explosion in your water heater. Don’t ignore consistent popping from your water heater.
