What is a common cause of water heater failure?

Sediment buildup in the tank is a common cause of water heater failure due to the operational nature of water heaters. Over time, minerals and debris present in the water accumulate at the bottom of the tank. This buildup can insulate the water from the heating element, causing it to work harder to heat the water to the desired temperature. As a result, this additional strain can lead to overheating, decreased efficiency, and ultimately, premature failure of the unit.

Moreover, sediment can create a breeding ground for bacteria and can lead to rusting in both the tank and the connected plumbing fixtures. Regular maintenance, including flushing the tank to remove sediment, is crucial in extending the lifespan of a water heater and ensuring it operates efficiently.

While other factors, such as power surges, improper installation, and excessive temperature settings can contribute to water heater issues, they are less directly related to the operational degradation that sediment buildup can cause over time.
