Inspect your T&P valve – Traditional storage tank style water heaters have a T&P (temperature and pressure) valve that releases excess pressure and keeps your water heater from becoming a bomb. Test it regularly – it should release some water when you flip the lever and then go back into place.
Pressure is often a critical factor in causing a water heater to explode. If the pressure builds up within the unit to an unbearable level, an explosion can occur. Additionally, a water heater can explode due to a fire. If the unit or the area around it catches fire, it can lead to a catastrophic explosion.
According to the Insurance Institute for Business & Home Safety, the average storage-type water heater only lasts about 10 years. By the 9-year mark, more than 40 percent have burst, and just 6 years after setting up your new model, there's still a 15 percent chance it will explode all over your basement.
A water heater explosion can cause significant damage to your home, and thankfully, most homeowners insurance policies do cover such events. However, the coverage may be subject to certain conditions, such as proper maintenance and adherence to safety codes.
Hot water heater replacement is typically excluded from your homeowners insurance coverage unless it breaks as a result of a covered peril, such as a house fire or hurricane. Because of this, it's often recommended to purchase extended warranties on expensive home appliances that you hope to last a long time.
Typically covered: losses caused by water abruptly leaking from a pipe inside the home, frozen/burst pipe if reasonable care is used to maintain heat in the home, water backing-up through a sewer or drain (with Back-up of Sewer or Drain endorsement) and water damage to your home caused by ice dams.
Warning Signs Your Water Heater Needs Replacement
A completely drained and non-functioning tank. Faulty pressure relief valve. Loud rumbling or banging noises. Rotten egg smells indicating potential gas leak.
What Is Causing a Popping Sound in My Water Heater? Minerals and other particles in your water supply can cause sediment and scale buildup. The popping noise comes from boiling water beneath the sediment. While the noise is not dangerous, excessive sediment can result in several problems for your water heater.
Popping Noise
Another sign of a potential explosion waiting to happen in your water heater would be those frequent popping noises you hear as sediment buildup settles to the bottom of the tank. The sediment blocks the heating element, creating a barrier between the heat source and the water in the tank.
An exploding water heater can cause catastrophic damage, not only to your plumbing and to your home, but can also be deadly. The sheer force of the released pressure from within the tank and the shards of shredded metal and gallons of scalding hot water suggest disaster for anyone close to the tank when it pops.
Thanks to modern safety features and regulations, water heater explosions are rare. In 2022, 108 incidents involving hot water heaters were reported to the United States Consumer Product Safety Commission.
While today's water heaters are better designed than older models, they still require regular maintenance in order to prolong their lives. With regular inspection, draining, and flushing, you can expect a gas water heater to last anywhere from 8-12 years and an electric water heater to last anywhere from 10-15 years.
Bad Thermostats
The thermostat's role is to regulate the water temperature inside the tank. If a thermostat is malfunctioning, it can cause the water heater to overheat, leading to a circuit overload and tripping the breaker.
Should you drain your hot water heater every year? Yes, but that's really just the bare minimum. You should really drain and flush your water heater twice-per-year: once in the spring, and then again in the fall. The reason why comes back to what a water heater is flushing out: minerals and sediment.
Knocking, banging, or popping sounds can mean sediment buildup, water hammer, or heat trap issues. Inconsistent water temperatures or a lack of hot water.
When this happens, you can usually solve the problem by flushing the water tank out. However, if banging, cracking, popping, or rumbling noises persist, you should call a technician, as you may be experiencing a more complicated and dangerous issue in the tank, potentially requiring you to replace your whole system.
This doesn't happen often, but if the pressure inside the container builds to a certain level, the heater might explode. If you're wondering what causes too much pressure in a hot water heater, we have covered all you need to know. You may have also noticed that your water heater sounds like a tea kettle when it's on.
However, electric water heaters can explode and cause fires, too.
Some common reasons for claim denials include: Insufficient evidence or information: The burden of proof falls on the injured party. State Farm might deny your claim if it believes you have insufficient evidence to prove how the car accident occurred or the severity of your damages.
Negligence. Your water damage insurance claim can be denied if you've failed to perform proper maintenance. For instance, if a pipe freezes and bursts because you didn't properly heat your home or your water heater explodes because it wasn't maintained regularly, your claim may be denied.
Insurers, like State Farm or GEICO, do not have a fixed number of claims that automatically lead to policy cancellation. This is more likely to happen if you have three or more claims, a record of DUI, at-fault car accidents with high bodily injury and property damage costs and other traffic violations.
