What Causes A Water Heater To Explode

4 Signs Your Water Heater is About to Explode

While we seldom consider it, our water heater is basically a gigantic time bomb that has the ability to explode, inflicting catastrophic damage and tearing your home apart if not properly maintained. When explosions go wrong, they may cause major property damage, as well as injuries and even death in some cases. Failures or explosions of water heaters can occur as a result of improper installation or service by unlicensed plumbers. If such negligent conduct result in injury to you or your family, or cause damage to your property, you should speak with a Houston water heater explosion attorney to see if you may be entitled to financial compensation.

Signs your Water Heater is about to Explode

Water heater explosions are extremely rare, but when they do occur, the consequences may be catastrophic. Do not wait for a disaster to strike. Here are some of the warning indications that your water heater will give you before it fails. It is customary for the pressure release valve to be situated on the side of the heater, towards the top. It opens when the pressure inside the tank reaches dangerously high levels, releasing water and allowing the pressure to return to normal levels. If the valve is leaking, it signifies that there is too much heat or pressure inside the tank, which causes it to malfunction.

Furthermore, if the valve is worn out or has been replaced several times, it indicates that it is unable to manage the pressure or heat in the tank and may eventually fail, resulting in an abnormally high level of pressure being trapped in the tank.

  • If you notice this smell, turn off the water heater immediately.
  • You may experience problems with your heater if it continues to make a popping or banging noise, similar to that created by a popcorn maker.
  • As a result, the burner must operate for a longer period of time to heat the water, raising the temperature within the tank.
  • Explosions can occur as a result of improperly placed heaters, heater controls, and gas connections.
  • Water heater explosions are preventable if you follow these guidelines.
  • Check that your heater’s pressure release valve is properly operational, and replace it if necessary. Maintain the temperature of your heater between 120 and 125 degrees at all times. Anything beyond this raises the internal temperature and causes scorching hot water to be released. At least once a year, ensure that your heater is maintained and cleaned out. Always check to see that your plumber is a licensed and experienced specialist.

Common Water Heater Injuries

Inspect and repair the pressure release valve on your heater if it is not functioning properly. Keep the temperature of your heater between 120 and 125 degrees at all times! Every degree over that raises the internal temperature and causes searing hot water to be released. Every year, make sure that your heater is maintained and cleaned out; Constantly check to see that your plumber is a properly licensed specialist.

Carbon MonoxideWater Heaters

Carbon monoxide poisoning is another possible hazard associated with a faulty water heater. The possibility of carbon monoxide poisoning from a water heater when it is neglected, inadequately fitted, or poorly vented should not be underestimated. Without a working carbon monoxide detector placed nearby, carbon monoxide can be unnoticed for long periods of time. When a carbon monoxide leak occurs, anyone who is home may endure headaches, dizziness, nausea, disorientation, and, in the worst case scenario, death if they do not get to fresh air as soon as possible.

Legal Help for a Water Heater Malfunction

For those who live in a rented house, you may be able to recover compensation if your landlord has been irresponsible in maintaining the water heater in your residence. It is also possible that malfunctioning water heaters might result in a product liability case if they were constructed wrongly, which could be pursued in court. Immediately consult with a Houston water heater explosion attorney if you have been hurt or have suffered property loss as a consequence of a failed water heater. A third party may have been negligent in their actions, and you may be entitled to compensation for your damages.

An explosion in a hot water heater can cause significant property damage, personal harm, and even death. Fortunately, there are very apparent prevention measures and warning indicators that should be kept in mind at all times. The information in this page will provide you with all of the information you need to know about preventing an explosion of this nature, as well as what to do if one does occur.

Water Heater Explosion Causes

An explosion caused by a water heater has the potential to utterly demolish your residence. Water heaters rely on both high pressure and high temperatures to function properly. The most common cause of a water heater explosion is when one (or both) of these parameters reach unsafe levels that cannot be handled by safety measures such as the temperature and pressure relief valves. Extremely high temperatures can cause a buildup of gas within a water heater, which can result in an explosion in one frequent scenario.

  • It continues to accumulate until the tank is essentially transformed into a nuclear weapon.
  • Anyone who is in close proximity to the water heater will very certainly be hit by a combination of searing hot water and debris, not to mention the enormous power with which these explosions occur.
  • Everyone, including those who are not in the same room as the water heater, is at risk of death or serious harm.
  • Obviously, this is detrimental to the structural stability of your home, as you may understand.
  • Watch the video below to see how severe it can be.

Both of these issues affect the structural integrity and functionality of the heater, resulting in water gushing out of the unit, causing damage to your property and the possibility of serious injury.

Note: A Water Heater Gas Explosion Is Something Different

Gas from a water heater (or any other source, actually) can explode when it has filled the room and a spark (typically from the pilot light, although it might also be caused by anything as simple as a lighter) ignites it. As a result, the explosive force itself does not come from within the tank in this situation. However, it can still be quite lethal in some cases. Such explosions often demolish entire homes and kill all of the people inside. These explosions occur as a result of a malfunctioning thermocouple in your water heater, which is relevant to this article.

Water Heater Explosion Statistics

In spite of the fact that reliable hot water heater explosion data are difficult to come by, they happen frequently enough that you read about them in the news on a regular basis. Even though it is just February 2020 at the time of writing, there are already multiple news pieces from 2020 that chronicle similar instances. It occurred in Russia, California, Illinois, and Alaska, to mention a few places where it occurred. Aside from being widespread, such explosions are also common enough to require significant investments and research into possible remedies.

Let’s take a look at some of the most prevalent warning indicators to see if they might help you become more attentive.

Water Heater Explosion Warning Signs

Water heater explosion warning indicators to look out for include a leaky pressure relief valve, which is one of the most common. For whatever cause, a leak of this nature indicates that the valve is unable to effectively handle the pressure within the tank and must be replaced. As you recall, this is one of the most prevalent causes of major tank explosions, and it is also one of the most dangerous.

A Consistent Popping Noise

Water heaters in Phoenix are particularly vulnerable to silt buildup. Arizona’s water is very hard, which means it has a high concentration of silt. If you do not have a water softener installed, this sediment will accumulate in your tank and compromise the structural integrity of the tank. The popping sound is the result of water seeking to escape from beneath the sediment layer of the sediment layer. When the coating has grown to this thickness, it indicates that the heating element will have to work more than usual to attain the necessary temperature.

It is possible for an explosion to occur when an excessive temperature and incorrect pressure relief valve performance are coupled.

The Pressure Relief Valve is Constantly Open

Especially prone to silt buildup in Phoenix are water heaters. Arizona’s water is very hard, which means that it includes a high concentration of sediments. Without a water softener installed, this sediment will accumulate in your tank, compromising the structural integrity of the vessel. The popping sound is the result of water seeking to escape from beneath the silt layer of the lake. When the coating has grown to this thickness, it indicates that the heating element will have to work more than usual to attain the required temperature.

It is also possible for this debris to block your temperature and pressure relief valves. Excessive temperature mixed with poor pressure relief valve operation might result in an explosion when these conditions are present.

A Leaking Tank

Water heaters in Phoenix are particularly prone to silt buildup. The water in Arizona is very hard, which means it has a high concentration of silt. Without a water softener installed, this sediment would accumulate in your tank, compromising its structural integrity. The popping sound is caused by water seeking to escape from behind the sediment layer. A coating this thick indicates that the heating element must work extremely hard to attain the specified temperature. This silt can also block the temperature and pressure relief valves in your home or office.

How to Prevent a Water Heater Explosion

Consider the following scenario: you’ve seen one of the aforementioned warning flags. What happens next? Well, for starters, if you fear an explosion is impending, you should turn off the water heater’s electrical and/or gas supply pipes. Follow the directions in your unit’s handbook for the proper procedure to be followed when completely turning off the heater. Once you’ve done so (which should help to mitigate some of the impending dangers of an explosion), contact a professional for assistance.

Attempting to fix your water heater on your own may end in numerous deadly situations (such as this one, in which a family lost their father as well as their house), and many of these incidents are preventable.

Water Heater Explosions: What NOT To Do

Additionally, avoid performing the following tasks on your own if you have a water heater that you are concerned can rupture:

  • Insisting on using tape to cover a puncture in your tank will simply raise the pressure in your tank and the chance of an explosion
  • More than a year has passed without you getting your water heater tested
  • Having untrained or untrustworthy professionals operate on your water heater for a lengthy period of time
  • Leaving any problem unaddressed for an extended period of time

In fact, explosions caused by water heaters are not simply a myth; they occur on a regular basis. Water heater explosion causes, warning signals, and prevention measures were all discussed in detail in this piece, which can be found here. You should now be fully informed about what to do if you fear your water heater is ready to blow up or otherwise malfunction.

Signs Your Water Heater Is Going to Explode in Your Home

The occurrence of a domestic water heater explosion, while rare, can occur and can be fatal. Explosions are possible with both gas and electric tank water heaters, and are more likely to occur with ones that have been neglected. When you recognize the warning indications of a potential water heater explosion, you may contact a plumbing company promptly to prevent a disaster from occurring.

Factors Leading to Water Heater Explosions

High internal temperatures and pressure can also lead to the explosion of a water heater. In order to keep levels from reaching too high, units are fitted with safety devices. If such mechanisms fail, an explosion may occur. When the temperature of the water heater is set too high, thermal expansion of the water causes the pressure inside the tank to rise to dangerously high levels. The sediment that has accumulated at the bottom of the tank acts as an insulator, causing temperatures to rise over a safe threshold.

Other component flaws can result in elevated temperatures and, as a result, elevated atmospheric pressure.

Gas leaks can increase the likelihood of a hot water heater exploding and the likelihood of a fire erupting.

Signs Your Water Heater Is Going to Explode

When the temperature and pressure grow above a certain point, the system emits a series of warning signals. If you see any of the following indicators that your water heater is about to blow up, contact an emergency plumbing repair agency immediately.

Leaking Temperature and Pressure Relief Valve

The T P valve is responsible for controlling the temperature and pressure within the hot water heater tank. When this valve leaks, it indicates that the component is unable to withstand the interior tank’s pressure. Deficiencies in the T P valve are a major contributing factor to water heater explosions.

Always Open T P Valve

It opens when internal pressure reaches a specified set point, which allows thermal expansion to be relieved and pressure to be reduced when the T P valve is operating as intended. The valve also opens when the temperature of the water reaches a high set point, enabling cold water to enter the tank and mix with the hot water, lowering the temperature of the water. In either case, the valve closes as soon as the troublesome conditions have been alleviated. A constant open state of the T P valve shows that there is a continuous problem with internal pressure and water temperature, which might result in an explosion if the valve fails.

Popping Noises

Sediment from the water supply accumulates at the bottom of the water heater when tanks are not properly maintained and cleaning is not conducted on a regular basis. Thick layers of silt act as an effective barrier between the water and the heating components, and temperatures rise as a result of the heating elements’ inability to successfully heat the water supply. Popping happens as a result of the boiling of water trapped below the sediment and up against the heating source. A bursting sound indicates the presence of silt as well as the possibility of overheating as a result of the conditions described above.

Brown Water

Sediment from the water supply accumulates at the bottom of the water heater when tanks are not maintained and flushing is not conducted on a regular basis. Thick layers of silt act as an effective barrier between the water and the heating components, and temperatures rise as a result of the heating elements’ inability to successfully heat the supply of water. Popping happens as a result of the boiling of water trapped below the sediment and up against the heating elements. Because of the above-mentioned parameters, a popping sound indicates the presence of silt and the possibility of overheating.

Rotten Egg Odor

Another indicator that your water heater may have burst is the stench of rotten eggs surrounding it, which suggests that there is a gas leak in the area.

Gas leaks can occur as a result of improper installation, broken gas lines, and other system problems, among other reasons. The pilot light on the water heater has the potential to ignite the gas, resulting in a violent explosion and fire.

Protect Your Household: Watch for Signs Your Water Heater Might Explode

An explosion in a water heater might be quite dangerous. A hot water heater tank that explodes as a result of this catastrophic system failure has the potential to inflict substantial damage to the home and its plumbing system, as well as hurt or kill anyone who are inside the house. Stay alert for symptoms that your water heater is about to burst, and contact your plumber right away if you suspect a leak or other emergency plumbing repair. For after-hours emergency assistance, call Grove HeatingCooling.

3 Things That Can Cause Your Water Heater to Burst – Plumbing Today

Consider the following scenario: you’re sitting at home when, all of a sudden, your ceiling falls in, causing water to pour out everywhere. What is the root of the problem? It is not a storm; rather, it is the result of a ruptured water heater. If you want to see what a ruptured water heater can do to your house, watch this 1-minute video. According to the Insurance Institute for Business and Home Safety (IBHS), this calamity is one of the top five causes of home water damage, resulting in an average loss of $4,444 per event after the deductible has been paid.

But do you think that will happen to you?

  1. Rust is corroding the tank due to sediment buildup. Internal pressure that is excessive

We’ll go through each of these concerns in further detail, as well as how you might avoid them in the future.

1) Sediment build-up

The problem is that sediment (minerals from your hard water) accumulates at the bottom of your water heater’s tank over time. This mineral coating acts as an insulator between the water and the burner, causing it to have to run longer to heat the water, causing it to overheat and degrade the tank’s structural integrity. Bradford White is the photographer that captured this image. If any of the following apply to you, you have this problem: There is a popping and pounding sound coming from your water heater.

It’s similar to the way boiling water raises the rim of a saucepan.

2) Rust corroding the tank

The issue is that your water heater is built of steel, which is mostly composed of iron. This means that over time, the water will corrode the tank’s metal walls. In the case of your water heater, a “sacrificial” anode rod serves as a rust prevention element on the inside. During the rusting process, this 3-5 foot rod takes the place of the tank (thus the term “sacrificial anode rod”). However, as soon as that rod begins to weaken, your water heater will begin to corrode and fail. If you notice that your hot tap water has a brown or rusty tint, you have this problem.

A new anode rod should be replaced once every 4-5 years, or even sooner if you have a water softener installed in your home. Check out this video to learn how to repair an anode rod properly.

3) Too much internal pressure

What happens to a balloon if you pump enough air into it is the mystery here. POP! The same problem occurs with water heaters. If there is an excessive buildup of pressure in the tank, it will ultimately leak and rupture. And if the pressure becomes unbearable, the tank will actually burst, transforming into a hybrid of a bomb and a rocket. Kaboom! Source:MythBusters Fortunately, your water heater avoids this problem from occurring by utilizing its T P (temperature and pressure) pressure release valve.

  • Bradford White is the source of this information.
  • If your water heater’s T P valve continually opening to discharge water, you may be experiencing this problem.
  • Preventative measures include: A build-up of pressure in the tank occurs when you set the temperature too high (140-145 degrees).
  • If you go any higher than that, you will not only raise the pressure in the tank, but you will also increase your chances of getting scalded.
  • The tank’s valve can be found on either the top or side of the tank.
  • ).

The best way to prevent water heater bursts

While you can easily perform all of these maintenance procedures on your own, it’s easy to forget about them. As a result, the most effective strategy to prevent your water heater from exploding is to call a plumber to do annual maintenance on it. As a result, you may enjoy the peace of mind you desire without having to worry about the upkeep. We can assist you if your water heater has not had expert maintenance performed in the last year or longer.

Even the spanking newAO Smith, which is far safer than traditional boilers, is not without flaws. Here’s everything you need to know about the dangers of water heater explosions, including how to avoid them.

Can a Water Heater Explode?

Your water heater has a limited lifespan during which it will be subjected to a great deal of strain. Water heaters that are not properly maintained or replaced on a regular basis, as well as those that are not properly maintained or replaced on a regular basis, have a considerably higher probability of exploding.

When a heater fails, or even worse, explodes, it can cause significant water damage to your property.

What Causes a Water Heater Explosion?

There are a variety of potential reasons of a heater explosion, but pressure is the most serious danger to be aware of. A faulty T P valve, excessive sediment, or a faulty anode rod are all potential hazards that might result in a pressure explosion. Another probable reason is a gas leak, which poses a significant fire hazard and should be investigated immediately.

Signs Your Water Heater is Going to Explode

Depending on who is to blame, you may experience a variety of symptoms. In the case of a sulfur or rotten egg odor coming from outside the tank, it is almost probably a gas leak, whereas a sulfur odor coming from your faucets indicates a colony of bacteria within the tank. As with pings in the pipes, brown water can also indicate rust or silt accumulation in the system.

How to Prevent a Water Heater Explosion

Proper maintenance, as well as replacing the water heater when faults or leaks begin to develop on a regular basis, are both effective techniques to avoid a catastrophic explosion. There are a few simple techniques to keep your heater in good working order, and none of them necessitate the use of a plumber, unless you decide you want one. A water heater should be properly checked at least once each year, unless symptoms are discovered, and periodic maintenance should be performed at that time to ensure that the heater is operating at top performance levels.

T P Check

Water heaters have a temperature and pressure relief valve (also known as a temperature and pressure relief valve or TPR or T P), which is often situated at the top or high on one of the sides of the unit. Testing the valve twice a year is simple and takes only a few minutes. Simply place a bucket beneath the valve, dress in clothing that will protect you from any scorching water that may splash on you, and turn the valve switch up for around five seconds. During the inspection, it should be capable of releasing water.

Temperature Check

The temptation to leave the thermostat at its maximum setting is strong, but doing so can actually reduce the lifespan of both your water heater and the temperature control valve. The temperature should be set around 130 degrees in the majority of situations, with no temperature setting greater than 140 degrees. As a result of the increased pressure created by hot water, the TPR valve may be forced to operate more often, eventually wearing it down and gushing hot water all over the floor.

Anode Check

In your tank’s water, the anode is a corrosive agent that draws corrosive agents that attract the anode. This causes the rod to corrode and degrade rather than the water heater’s walls. When the tank’s walls become too thin and finally burst, the possibility of an explosion increases significantly. You should inspect the anode once a year and replace it if necessary. Remember that there are various different types of anode rods available, so you may want to consider investing in the rod that best meets your household’s needs.

Gas Check

If you notice the smell of sulfur near a gas water heater, it is critical that you turn it off immediately. This has the potential to create a significant fire danger and explosive risk. Keep the gas off until the leak has been identified and corrected. Professional assistance is suggested, however if you’ve limited the problem down to a malfunctioning gas control valve or its connection, the controls are fully on the outside of the tank and may be accessed without opening the tank. It is rather simple to replace a faulty gas control valve as a result of this.

This odorless gas can induce a variety of symptoms, including dizziness and difficulty concentrating, among others. Because too much carbon monoxide can be fatal, it is recommended to have a carbon monoxide detector near the water heater in case CO2 gas escapes.

Regular Flushing

Over time, silt can build up in the tank, causing the water temperature to become uneven and the tank pressure to rise, among other things. Flushing out the tank on a yearly basis can significantly lessen these risks while also allowing your anode to operate more efficiently. The procedure takes longer than the other maintenance jobs on this list, but the benefits are typically tangible and tangible results may often be felt.

Install Water Heater Above Floor Level

It is preferable to have a gas water heater built 18 inches above the ground level, however this is not always practicable in all situations. For the simple reason that a variety of liquids, including gasoline, paint thinner, lacquer, brake cleaner, contact cement, and other dangerous products, may all be kept together in the same space (ie: garage). If these materials are utilized in close proximity to a water heater or if they are not properly sealed, the fumes can reach the gas control valve and cause an explosion.

When is the last time you were concerned about your water heater exploding? Learn about the warning signs of a water heater explosion and what you can do to avoid an explosion from occurring to alleviate your anxieties of experiencing one. An explosion in a water heater tank occurs when an excessive amount of pressure builds up inside of the water heater tank. Because tankless water heaters do not have a storage tank, they are less likely to burst than traditional gas water heaters, conventional electric water heaters, and heat pump water heaters that employ storage tanks.

Water Heater Explosions

Explosions caused by water heaters cause significant damage. In reality, there are several news tales about people who have died as a result of water heater explosions. Because of the tremendous tragedy that may result from a water heater explosion, it is critical for every homeowner to understand what causes water heater explosions and how to avoid them.

What Causes Water Heater Explosions?

When water heaters are in use, they generate pressure. When the temperature goes too high or the water pressure is too high, water heaters produce greater pressure. If the pressure in the water heater rises to dangerous levels, the water heater will release the pressure by opening the pressure relief valve on the water heater. If the pressure relief valve fails to operate properly, the pressure will not be released automatically, which might result in an explosion. Additionally, if the pilot light comes into touch with gas via a gas leak or combustible substance, an explosion may ensue.

Gas water heaters are somewhat more at danger than electric water heaters as a result of this, although electric water heaters are also susceptible to explosion. Many gas water heaters are mounted on water heater platforms that are 18″ above the ground to reduce the likelihood of an explosion.

Water Heater Explosion Warning Signs

Some of the warning indications that your water heater may be about to blow up are:

  • Noises coming from the pressure valve
  • Leaking at the pressure valve
  • Sulfur smell

Popping/Whistling Noises

While your water heater is operating, silt that has accumulated in the bottom of the tank can shake around, generating popping sounds as the sediment moves about. As silt accumulates, it has the potential to harm the thermostat, causing it to work harder, or to damage the pressure relief valve. Whistling noises are considerably more frightening since they are unpredictable. The whistling is caused by excessive use of the pressure relief valve, which indicates that it is required to open and release excess pressure on a frequent basis.

Leaking at the Pressure Relief Valve

Pressure might cause the valve to become overworked and leak as a result of excessive strain. In addition, leaks might develop over time as a result of normal wear and use. If the pressure relief valve has to be opened and closed on a regular basis, you may see visible leaks around the valve’s perimeter. When the valve is opened, water will be allowed to flow, giving the impression of a leak. Before concluding that the valve requires replacement, look for signs of a leak at the connection.

Sulfur Smell

As a safety measure, gas contains a chemical that when exposed to oxygen, emits the smell of rotten eggs or sulfur, which will reach your nostrils when there is an explosion or leak of natural gas. This may become exceedingly hazardous because if the gas comes into contact with the pilot flame of many gas water heaters, the water heater will explode, resulting in serious injury or death.

News Coverage of Exploding Electric Water Heater

In this tale of an electric water heater that encounters too much pressure buildup due to overheating and explodes out of the house like a rocket, impacting 300 feet away, you can see the terrible results of a water heater bursting inside the home. When people hear about incidents like these, they begin to wonder if a water heater explosion may be fatal. This is extremely unusual, and fortunately no one was injured.

MythBusters Exploding Water Heater

To demonstrate how violent an explosion may be, Adam and Jamie from the award-winning television show Mythbusters decide to put the myth of exploding water heaters to the test for themselves.

How To Avoid A Hot Water Heater Explosion

Everyone, including homeowners, has a responsibility to take reasonable steps to avoid hot water heater explosions. These suggestions can assist you in preventing your water heater from accumulating enough pressure to cause it to explode.

Verify Safe Temperature

Check to see sure your hot water heater is producing hot water at the proper temperature for your needs. You want to keep the temperature of your domestic water heater at 120°F or below, in most instances. To check the temperature of your water heater, test the thermostat on your water heater.

It is necessary to troubleshoot the problem immediately if the water heater is producing water at a temperature higher than the temperature setting on the water heater. Failure to do so will result in a buildup of too much pressure in the water heater tank.

Install a Water Softener

Because hard water includes more minerals than soft water, it causes increased sediment accumulation in your water heater tank. Install a water softener in your main water line to limit the amount of sediment accumulation that can interfere with your water heater’s thermostat and cause it to become too hot, resulting in high pressure levels in your system.

Flush Water Heater Regularly

It is impossible to completely avoid mineral deposits in your water heater. As a result, you should flush your water heater on a regular basis to ensure that any silt in your tank is removed. You will need to follow the easy methods below in order to cleanse your water heater: Step one is to turn off the water heater’s power. Remove the electricity from the water heater by turning it off at the circuit box as a preventative measure. Step 2: Turn off the cold water valve. The cold water valve at the top of the water heater tank must be closed in order to prevent new water from being introduced into the water heater tank.

  • To empty the contents of the water heater tank, turn on the drain valve located at the bottom of the water heater tank.
  • Step Four: Shut off the drain valve.
  • Step 5: Turn on the cold water valve.
  • Check to see that no water is escaping via the drain valve.

Replace Water Heater Drain Valve

The majority of water heaters are equipped with plastic drain valves that do not endure for the whole life of the water heater and must be replaced. Drain valve replacement is required when you discover that the drain valve is beginning to leak at the connection. When it comes time to replace your drain valve, consider upgrading to a metal drain valve, which will last far longer.

Replace Water Heater After 10 – 15 Years

It is recommended that you replace your tank-style water heater every 10 to 15 years. The longer you continue to use the equipment over its projected life expectancy, the more harmful it will become. Replacement of your water heater as soon as possible is recommended to avoid problems that might cause damage to your entire home and perhaps lead someone to be seriously harmed.

Use Water Heaters Without Pilot Lights

Many homeowners prefer gas water heaters over electric water heaters and do not want to make the financial commitment to change to a tankless water heater system, which is more expensive. Many gas water heaters, on the other hand, still rely on a pilot light to ignite the gas burner.

When this open flame comes into touch with gas or other flammable substance, it may become extremely deadly. Fortunately, many gas water heaters now employ electronic ignition, which eliminates the need for a pilot light and thus eliminates the risk.

What Should You Do If Your Water Heater Explodes?

In the event that your water heater bursts, it will do a tremendous amount of damage. If you have a water heater explosion in your house, follow these simple procedures to prevent more damage.

Step One:Check on Family Members

The first and most important thing to do is to make sure that no one in your home needs medical treatment as a result of the explosion. An ambulance should be sent as soon as possible if someone need medical assistance. In the event of a fire or other risk as a result of the explosion, you must also contact the appropriate authorities. If everyone looks to be in good health, remove everyone from the house.

Step Two: Turn Off Power, Gas, and Water to Home

It is necessary to switch off the water, gas, and electricity to your home in order to avoid further risk or damage.

Step Three:Breathe and Assess the Situation

As soon as you are certain that everyone in your household has been saved from harm, you may take a deep breath and calmly survey the damage to your property.

Step Four:Call Your Insurance Company

As quickly as possible, contact your insurance carrier for assistance. Fortunately, most insurance companies enable you to make a claim at any time of day or night, so you shouldn’t have to wait until the following morning.

Step FIve:Restore Power, Gas, and Water

Once your home is safe, turn back on the electricity, gas, and water.

Step Six:Buy New Water Heater

Following your conversation with your insurance provider, you should begin looking for a replacement water heater. Consider switching to a tankless water heater that does not have the potential to explode in order to prevent another explosion from occurring.

7 Signs Your Water Heater Is Going to Explode

Because your water heater produces a large amount of hot water on a daily basis, it need regular maintenance to guarantee that it is in good working order. Water heaters, on the other hand, provide a number of threats and concerns, including flooding and leaks, with the most hazardous being the possibility of an explosion. If your appliance is not properly maintained, it has the potential to cause an explosive reaction. The following are indicators that your water heater is about to explode: leaking tank water, a defective pressure relief valve, hazy water, popping noises, and a lack of hot water in the faucet.

It will be discussed in this post what indicators you should look for to determine whether or not your appliance is at risk of exploding in the near future.

Being aware of these indications will allow you to take the required actions as soon as you see them, averting any potentially disastrous repercussions.

1. Leaking Tank Water

Does your unit appear to be sitting in a pool of water? Corrosion can cause cracks and fractures in the water tank’s walls and bottom. Warm water might escape from the water heater tank as a result of these cracks and fractures in the tank. This means that you need to get your leaky appliance repaired or replaced immediately. The water supply to your home should be shut off immediately if the leak is urgent. Please keep in mind that this is only a temporary solution for the time being. You must contact your plumber as soon as possible in order to get these leaks repaired.

2. Malfunctioning Temperature and Pressure Relief Valve (TPR)

If the TPR valve on your appliance is leaking, you must replace it as soon as possible. When the pressure or temperature in your device reaches dangerously high levels, the valve opens to prevent a potential explosion from occurring. Corrosion and rust can build up in the valve, causing it to stop operating completely. If a faulty TPR valve is not repaired in a timely manner, it can cause significant harm. In fact, it has the potential to cause the water to boil past its boiling point, converting to steam and causing the water tank to blow up.

Test the valve by lifting and lowering the lever many times to identify the problem.

If you notice that no water is coming out of the pipe, you should consider replacing the TPR valve with a new one.

3. Cloudy Water

Is the water that comes out of your appliance cloudy? Does the water have a metallic odor? The presence of musty-smelling water indicates that your equipment is malfunctioning. Mineral deposits travel throughout the appliance and contaminate the hot water that comes out of your faucet as a result. Their metallic flavor and odor are present as well as their presence. The deposits have the potential to harm faucets and clog parts that regulate water flow. The presence of orange or red colored water flowing out of the unit also shows that the pipes and tank have been rusted and need to be replaced.

It is important to understand that drinking rusty water will not cause any major health problems.

4. Popping Noise

You should immediately contact a plumbing professional if your water heater is making rumbling, popping, or cracking noises. Because of the hard water and mineral buildup in your water, the noises emanating from your appliance are caused by mineral accumulation. During the formation of a coating of minerals on the surface of the water heater, a distinct popping sound is heard coming from the appliance. This is an indication that your unit is experiencing difficulties. The popping sound is caused by air pockets in the sediment layer that are boiled together with the water in the water heater tank, resulting in the popping sound.

If flushing out the sediment does not resolve the issue, it is likely that your device is experiencing a significant malfunction.

It is critical for you to understand that the strange noises emanating from your appliance are worrying and indicate that your appliance is on the verge of cracking, leaking, or explode. The most cost-effective alternative is to replace your water heater tank before it produces a costly leak.

5. Rotten Egg Smell

If you have a gas-powered device and you notice a rotten egg or sulfur smell around the outside of your unit, you most likely have a gas leak in your home or business. Propane and natural gas have a foul odor that reminds some people of rotting eggs or sulfur. When you smell carbon monoxide gas, it’s most likely due to the presence of ethanethiol (ethyl mercaptan), which gas companies add to propane and natural gas in order to make the gas recognizable by scent. If you suspect that your unit has a gas leak, you should turn off the gas to the appliance and hire a plumber to inspect and make any necessary repairs.

6. Carbon Monoxide Poisoning

Carbon monoxide gas, on the other hand, is an odorless and colorless gas that cannot be detected or seen. It is extremely harmful, and only a specialized instrument can identify it. It is unfortunate that carbon monoxide may cause mortality as well as bodily harm and disease. We want you to understand that carbon monoxide leaks are not something that happens all the time. They occur as a result of negligence, faulty installation and handling, as well as a lack of air in your HVAC unit. Symptoms of carbon monoxide poisoning include:

  • Fainting, chest pain, confusion, breathing difficulties, vomiting, weakness, headache, blurred vision, and dizziness are all possible symptoms.

In the event that you suffer many of these symptoms, you should leave your home immediately and get some fresh air. Most essential, you should immediately contact an expert to inspect your water heater, as well as the quality of the air in your home and your plumbing.

7. No Hot Water

Do you obtain hot water from the faucet after a lengthy period of time? A water heater that isn’t producing enough hot water is an indication of a problem. The majority of typical water heaters contain a storage tank that holds between 30 and 50 gallons of water (113 liters to 189 liters). After being heated by an electric source, the water in the tank begins to gather minerals that are present in it. These minerals accumulate near the bottom of the tank. And over time, these mineral deposits accumulate in the water storage tank, where they act as a barrier between the burner and the water, reducing its efficiency.

The higher the concentration of mineral deposits in the water, the harder your appliance needs to work to heat it.

It can also leak, resulting in a hefty water bill to cover the damage.

This problem may be resolved by cleansing your water tank on a yearly basis.

Main Causes of a Water Heater Explosion

A critical component in determining whether or not your water heater may burst is the amount of pressure that exists inside the appliance. If there is too much pressure in your appliance and it is not addressed promptly, an explosion will occur at some point. Water heaters are equipped with TPR valves, which allow steam or water to escape from the unit if the pressure or temperature becomes excessive.

You’ll avoid having your unit explode because of this. Additionally, combustible materials might enhance the likelihood of an explosion. When a water heater overheats owing to poor ventilation and is surrounded by combustible materials, it is in danger of exploding.

Some Useful Tips

In order to avoid your water heater bursting, there are a few things you should bear in mind.

  • Here are a few things to keep in mind in order to avoid your water heater exploding:


It is impossible to thoroughly clean your dishes and tableware without a water heater, which is why you must have one installed in your home. That is why it is critical that you maintain the condition of your water heater. A malfunctioning appliance may result in an explosion if not properly maintained. Water heaters, like any other equipment, require regular maintenance to ensure that they continue to operate properly for as long as feasible. It is possible that your appliance will fail if you check it and find rust and leaks in it.

Warning – Your Water Heater Can Explode

When you consider all of the advantages and services that water heaters provide, they are one of the greatest inventions of our time. A single water heater can provide all of the hot water you need for laundry, showers, dishwashers, and washers in your house! A tank-type water heater is the most common form of water heater seen in modern homes. Most commonly, a gas burner or electric coils are used to heat the water in this system. The tank’s purpose is to keep the water warm until another household utility wants hot water for a different purpose.

So, what causes these awful water heater explosions, and what can be done to avoid them in the future?

The signs of the water heater that is doomed for disaster

Installing a water heater incorrectly is often done by either the homeowners themselves or by engaging plumbers who are untrained and unethical in their work. Here are a few indicators of a faulty installation.

  • The fittings on the water heater’s top were soldered together. It is possible for the dip tube or other plastic pieces to melt if heat is given directly to the top of the water heater, resulting in substantial damage to the water heater. Faulty fitted controls can potentially result in an explosion, particularly if the gas connections are poorly connected or rusted.

Throughout the process of heating the water, pressure steadily builds up inside the storage tank. Normally, a pressure relief valve on your water heater would shut it off or relieve the pressure that has built up inside it. It is possible for your water heater to explode, though, if its temperature is set too high and pressure builds up more quickly than the pressure release valve can manage it. This safety valve automatically opens if the water temperature rises to 210 degrees Fahrenheit or if the pressure within the tank exceeds 50 pounds per square inch (lbs PSI).

  1. If the pressure relief valve is leaking, it indicates that something is wrong: either too much heat has built up inside the tank, or too much pressure has built up inside the tank.
  2. This has the potential to trigger an explosion.
  3. Did you aware that your water heater has to be serviced on a regular basis?
  4. If your home is linked to the city’s municipal water supply, the cold water that enters the water heater tank has a high concentration of contaminants that have been introduced into the system.

It is necessary to flush your water heater on a regular basis in order to remove all of the sediment that has accumulated inside of it. You should seek expert assistance if you are unable to do the task alone.

If your carbon monoxide detector continues to sound the alarm, there is a risk that there is an agas lineleak in the vicinity of your water heater, which might cause an explosion the next time the pilot light is turned on. A little igniting flare can cause a gas leak to erupt into a conflagration, resulting in severe injury or death. A carbon monoxide detector should be installed as soon as possible if one does not already exist. One day, it could just save your life. Steps to take to avoid a water heater explosion are outlined below.

There is no reason to be scared of your water heater; it is a dependable assistant in the home; nonetheless, in order to avoid any potential calamities, you should follow some simple guidelines.

  1. Your heaters and tanks should be maintained and serviced by a competent and experienced expert
  2. However, this is not always the case. Every two months, try to open the relief valve – it should be simple to do so
  3. And Every three years, it is a good idea to replace the temperature and pressure relief valve. Remove any paper, dirt, or dust that may have accumulated in the vicinity of the water heater. Also, clean the heater on the outside of the building. Provided your tank does not already have one, you should get one installed as soon as possible. Set the water heater or boiler to a temperature that does not exceed 180 degrees Fahrenheit. If at all possible, consider switching to a tankless water heater.

In order to have the peace of mind that your house water heater is a functional appliance rather than a potential bomb, contact a local, skilled, and dependable plumbing professional such as Downey Plumbing HeatingAir Conditioning to guarantee that you have that peace of mind.
