Although water heaters work hard, many people do not think much about them until something goes wrong. There are plenty of potential issues, and one that people ask about is whether a water heater can explode. While it is possible for one to explode, it is an uncommon occurrence. You can prevent a water heater explosion by monitoring your unit’s performance and keeping up with regular maintenance. This guide will explain how explosions can happen, how to prevent them and how to identify signs of danger.
Why Would a Water Heater Explode?
An explosion can happen if too much pressure builds up in the tank. Pressure can build up because of excessive overheating. Also, there is a temperature and pressure relief valve, which can function incorrectly and cause pressure buildup. The tank may explode if the pressure reaches an extreme level and has nowhere to escape. If a tank does explode, there is enough force from the pressure that it can cause serious damage and can injure anyone nearby. With gas-powered water heaters, there is also a risk of gas line issues. A gas leak can happen and cause an explosion if it ignites. However, explosions can happen to gas and electric water heaters.
Signs of Water Heater Explosion Risks
It is important to watch for signs of explosion risks regularly. Also, have a professional inspect the unit as often as recommended by the manufacturer or a licensed plumber. These are some danger signs.
T&P Valve Problems
Water heaters can handle some pressure, which the T&P valve usually helps regulate. However, a failing thermostat or valve can cause the pressure to rise to unsafe levels. The T&P valve can develop a leak. If this happens, call a plumber immediately.
Sediment Buildup
Sediment collects in the tank over time because of minerals in the water. That buildup causes the unit to work harder, and the resulting overheating can cause an explosion. Sediment collects at the bottom of the tank and traps water below it. As the tank heats up, it creates steam. You may hear rumbling and popping sounds when this happens. A plumber can recommend what to do if your unit has significant sediment buildup.
Overheating Unit
If the water that comes out is scalding, your unit could be overheating. Also, it may overheat if the thermostat is malfunctioning. Overheating is more likely to happen when the temperature is not within an ideal range. Most experts recommend keeping the setting at 120 degrees Fahrenheit in most cases. It should not exceed 140 degrees.
Corrosion or Rust
Rust and corrosion weaken the tank and can cause leaks over time. Also, they may cause it to burst. If you see rust in the water or outside the tank, it is damaged enough that you need to call a plumber.
Gas Smell
A gas leak near a gas-powered water heater can cause a serious explosion. If the gas is close enough to an ignition source, an explosion may happen. Although gas does not have an odor, utility companies add a substance to it that smells unpleasant. This makes it easier to detect a leak. You may notice a smell that resembles rotten eggs or sulfur if there is a gas leak. Evacuate your home immediately if you notice this smell, and stay out of the house until the gas company or a professional can assess the situation.
How To Prevent a Water Heater Explosion
Fortunately, most explosions that happen are preventable. If you prioritize maintenance and monitoring, you can keep your home and family safer. These are some ways you can reduce explosion risks.
Flush the Tank
Flush the tank every year. This helps prevent excessive sediment buildup, which reduces the risk of overheating. Also, it minimizes annoying noises. Flushing the tank involves several steps. If you do not feel comfortable doing this yourself, call a professional for assistance.
Monitor the Temperature
Always keep the temperature set within the range recommended earlier. If it exceeds 140 degrees, turn it down. Be sure to follow the correct safety steps if you need to adjust it. The steps differ for gas and electric units.
Test the T&P Valve Often
If you check this valve often, you can ensure that it functions correctly. Look for leaks or other signs of problems. A functioning T&P valve will release pressure when it gets too high.
Schedule Routine Maintenance
A licensed plumber should inspect your unit annually. If it needs any repairs, the plumber can tell you. Also, a plumber can tell you when your unit needs to be replaced.
