Here are the common risk factors that might lead to a water heater explosion -
1. Sediment Buildup
Over time, sediments like calcium and magnesium build up in the bottom of the water heater. This layer of mineral deposits insulates the heating element - which causes it to work harder. Ultimately, it will lead to overheating.
As a result, energy efficiency decreases, and the water heater must expend more effort to reach the desired temperature. Persistent overheating due to sediment accumulation can lead to pressure buildup, putting the tank at a higher risk of ruptures or even explosions if left unchecked.
2. Faulty Pressure Relief Valve
Water heaters have pressure relief valves. The pressure relief valve releases water if the pressure becomes too high. When this valve malfunctions or becomes clogged, it may fail to release the excess pressure. Thus causing the pressure to rise to a dangerous level. If left unchecked, the pressure builds up and causes an explosion.
A faulty pressure relief valve can fail to release excess pressure. This allows dangerous levels of pressure to accumulate. Regular testing of the pressure relief valve ensures it functions correctly, as even a minor malfunction can compromise the entire safety system of the water heater.
3. Thermostat Malfunction
A water heater’s thermostat regulates water temperature and prevents overheating. Also, the thermostat alerts the electronic ignition to shut down when the temperature of the water heater reaches the desired set temperature.
When the thermostat malfunctions - it turns your water heater into a ticking time bomb. This causes the water to reach unsafe temperatures - which increases the internal pressure significantly. The increase in the temperature and pressure increases the risk of burns from scalding water. When it cannot be managed, the excess pressure can cause the heater to burst.
4. Age Of The Water Heater
Older water heaters are more prone to wear and tear - which makes them more susceptible to malfunctions and safety issues. Over time, pressure relief valves, thermostats, and other heating elements degrade.
If you are not regularly maintaining them, the older units can accumulate substantial sediment buildup - which might cause component failure. This significantly raises the risk of overheating and pressure buildup - ultimately leading to a water heater explosion.

Warning Signs Of Potentially Damaged Water Heater
Here are some of the warning signs that say - “YOUR WATER HEATER IS DAMAGED!”
1. Popping, Banging, And Rumbling Noises
When there is sediment buildup in your tank - there are usually some odd noises, such as - popping, banging, or rumbling. As the water heats, trapped bubbles form around these mineral deposits, causing sounds as they try to escape.
If you’re continuously hearing unusual sounds from your unit - don’t wait! Consider calling a professional water heater repair to identify and address any potential risks related to the water heater.
2. Leaking Water
When you see water pooling near the water heater - know that water is leaking from your unit. This is a concerning sign of potential structural damage or tank failure. Small leaks might indicate weakened joints or valves - which can be fixed with small repairs. However, larger and continuous leaks could signal significant structural problems, which could lead to a blast.
Hence, it is advisable to address leaks promptly with professional repairs. This can prevent catastrophic failures and improve the heater’s longevity and safety. Emergency plumbers can help you fix your unit.
3. Rusty or Discolored Water
When you see rusty or discolored water - it is usually a sign of corrosion in your water heater. When sediments build up, they can corrode the internal parts of the water heater. This weakens the tank’s structural integrity.
Rust, another word for corrosion, of course, affects water quality. At the same time, it can also lead to the tank being weakened. If not addressed on priority, it can cause an explosion.
4. Irregular Water Temperature
When you notice fluctuating water temperature - it means your thermostat is malfunctioning. In addition, it can also signal other internal issues, such as - pipe issues, problems with dip tubes, faulty temperature knobs.
Out of everything - if the thermostat is not working well-meaning, if it fails to regulate heat properly, the water may get too hot or not hot enough. This results in an increase in the risk of scalds or system strain. If you notice inconsistent temperatures, scheduling water heater installation or repairs is essential to restore efficient, safe heating.

Expert Tip: How You Can Prevent Water Heater Explosion?
Here’s how you can prevent water heater explosion -
1. Regular Maintenance
It is advised to conduct bi-annual maintenance service to help spot early warning signs of water heater issues. Some common issues like sediment buildup or failing components can easily be detected during these inspections. Hence, this can prevent any water heater-related damage.
You can also perform basic maintenance by flushing the tank every six months. This helps remove sediment - which reduces the overworking and overheating of the water heater. This, in turn, reduces the risk of water heater explosion. Moreover, regular upkeep ensures your unit is serving you longer.
2. Check the Pressure Relief Valve
The pressure relief valve also needs to be checked every now and then to ensure it is functioning optimally. Check pressure relief valve is easy. All you need to do is - turn off the heater and place a bucket under the discharge pipe.
Next, lift the valve lever. If water flows out, the valve is functional. Once done, release the lever, and it should stop the flow. This simple test helps verify the valve’s ability to release excess pressure, a key safety feature. If you are unaware that the task seems too difficult for you - call a professional!
3. Set Temperature Appropriately
The water heater’s thermostat should be set between 120°F and 140°F - as per the US Department Of Energy. This prevents overheating and excessive pressure buildup. This temperature range is considered safe for household use. It reduces the risk of scalding and minimizing strain on the heater.
First, read the manufacturer’s instructions - it has all the information on how you can adjust the temperature. However, not all water heaters have an easy setup. In fact, several electric and gas water heaters have temperature controls hidden behind the access panel.
4. Replace Aging Units
Water heaters older than 10 - 15 years are more prone to malfunctions and safety risks. When you notice that your water heater has served you more than 10 years - it is time to replace it before you are left with an emergency decision.
Replacing outdated units with modern models reduces accident risks. That’s not all! It also incorporates improved safety features and energy efficiency. Hence, it is advisable to invest in a new water heater that offers long-term benefits and aligns with best practices for household safety.
5. Invest in a Thermal Expansion Tank
A thermal expansion tank absorbs excess pressure caused by water expansion in systems with high water pressure. It is a secondary tank that can help homeowners effectively reduce strain on the main water heater. This minimizes the risk of leaks or explosions.
If you are residing in an area where there is a fluctuating water pressure, expansion tanks are your best friend when ensuring safety.
There is a common question that every homeowner asks - you may have as well!
6. What Should I Do In Case Of A Water Heater Emergency?
Well, the answer is simple! The first thing you need to do is - turn off the water heater’s power (electricity or gas) and close the cold water valve to stop flow. This reduces pressure and risk.
Next, if you have a gas water heater - and you can smell a strange smell coming from the area where your water heater is - evacuate the area IMMEDIATELY. Once you are sure you and your family are away from danger - contact a licensed plumber for water heater repair to assess and repair the heater.
Takeaway
Regular maintenance, immediate inspections, and monitoring for warning signs are very important to keep water heaters safe and functional. If you hear strange noises, leaks, or inconsistent temperatures - never ignore them. They’re signals to act before minor issues escalate.
Early monitoring can help prevent several issues - from minor to hazardous! Though it is quite rare - water heater explosions are preventable. All you need to do is stay aware of your surroundings and ensure you are getting your water heater checked every year or bi-yearly.
