Common Causes of Water Heater Breakdowns

Water heaters are not immune to breakdowns, and recognizing the common causes can help prevent and quickly address issues. 

Some typical causes of water heater malfunctions include:

• Sediment accumulation: Minerals from hard water settle at the bottom of the tank, forming sediment that can reduce efficiency and speed up corrosion.
• Corrosion: Water heaters have anode rods to prevent rust, but once these rods are depleted, the tank can start to corrode, leading to leaks or system failure.
• Thermostat issues: A malfunctioning thermostat can lead to water that’s too hot or too cold, as it fails to regulate the temperature accurately.
• Heating element failures: The heating elements can burn out in electric water heaters, resulting in a complete loss of hot water.
• High water pressure: Excessively high pressure can strain your water heater, leading to premature wear and possible tank rupture.
• Age: Water heaters typically have a lifespan of 8-12 years. As they age, components wear out, and efficiency declines, leading to more frequent repairs and potential breakdowns.
• Improper maintenance: Neglecting regular maintenance, such as flushing the tank and checking the pressure relief valve, can lead to problems that may cause the unit to fail.
• Gas line issues: Leaks or valve failures in gas water heaters can disrupt service and pose serious safety risks.
