Why do water heaters explode and what are the potential causes behind this dangerous occurrence?

Water heaters can explode due to a buildup of pressure caused by overheating or a malfunctioning pressure relief valve. Other potential causes include sediment buildup, a faulty thermostat, or a gas leak. When the pressure inside the water heater exceeds safe levels, it can lead to an explosion, posing a serious safety risk. Regular maintenance and proper installation can help prevent these dangerous occurrences.
