A geyser bursting can cause a lot of damage and lead to expensive repairs. To avoid this kind of disaster, it’s important to know why a geyser might burst in the first place.
Here are some common reasons why geysers burst:
1. Too Much Pressure
If the pressure relief valve in the geyser gets blocked or stops working, pressure inside the tank can build up too much.
This valve is supposed to let out extra pressure, so if it fails, the pressure can make the tank burst.
2. Sediment Build-Up
Over time, minerals from the water can collect at the bottom of the geyser tank. This build-up acts like insulation, making it harder for the heating element to heat the water. As a result, the water can overheat, increasing the pressure inside the tank.
This added pressure weakens the tank and can eventually cause it to burst. Flushing the tank regularly can help remove sediment build-up, keeping the heating element efficient and preventing overheating.
3. Corrosion
Rust and corrosion can develop inside the tank, especially if the anode rod, which is designed to protect against corrosion, isn’t replaced regularly.
The anode rod attracts corrosive elements, preventing them from damaging the tank. However, if the rod gets too corroded, it can’t do its job, and the tank starts to rust. Corrosion weakens the tank, making it more likely to burst. Regularly inspecting and replacing the anode rod can help prevent this issue.
4. Faulty Thermostat
If the thermostat in the geyser isn’t working correctly, it can cause the water to get too hot. When the thermostat fails to regulate the temperature properly, the water can reach dangerously high temperatures, increasing the pressure inside the tank.
This heightened pressure can lead to a burst. Ensuring the thermostat is working properly and replacing it if necessary can help keep the water temperature in a safe range.
5. Manufacturing Defects
Sometimes, geyser tanks have weak points due to manufacturing defects or the use of poor-quality materials.
These defects might not be obvious at first but can cause the tank to fail under normal operating pressure, leading to a burst. Choosing a geyser from a reputable manufacturer and checking for any recall notices can help avoid this problem.
If you suspect a defect, consult with a professional to assess the tank.
6. High Water Pressure
If the water pressure entering the geyser is too high, it can stress the tank and its components beyond their capacity.
Over time, this excessive pressure can weaken the tank’s structure, making it more susceptible to bursting. Installing a pressure regulator on the main water line can help control the water pressure entering the geyser, reducing the risk of a burst.
7. Improper Installation
If the geyser isn’t installed correctly, it can put stress on the tank and its fittings. For example, if the pressure levels are set incorrectly or the mounting isn’t secure, it can lead to stress on the tank over time.
This stress can weaken the tank’s structure, increasing the likelihood of a burst. Ensuring that the geyser is installed correctly by a qualified technician can minimize the risk of problems due to improper installation.
8. Lack of Maintenance
Neglecting regular maintenance tasks like checking the pressure relief valve, inspecting the anode rod, and flushing the tank can increase the risk of a geyser burst.
Without proper maintenance, sediment can accumulate, corrosion can develop, and critical components can fail. Regular maintenance helps identify and address potential issues before they escalate, ensuring the continued safety and functionality of the geyser.
9. Old Age
Geysers have a limited lifespan, typically around 8 to 12 years. As they age, their components can deteriorate, and the tank’s structure may weaken, making it more prone to bursting.
It’s essential to monitor the condition of an older geyser closely and consider replacing it if signs of deterioration or increased risk of bursting are detected. Regular inspections can help determine when it’s time to replace an aging geyser.
Conclusion
Regular maintenance, proper installation, keeping an eye on water pressure, and replacing old geysers are all important. Make sure your pressure relief valves and TPR valves are working correctly. Do read these important geyser safety tips.
Taking these steps can protect your home and save you from costly repairs.
