How often should water heaters be flushed?

Flushing a water heater is an important maintenance task that helps to remove sediment and mineral buildup inside the tank, which can affect the efficiency and longevity of the appliance. Performing this maintenance annually is recommended because it helps ensure that the water heater operates efficiently, providing hot water at the desired temperature while preventing potential issues such as reduced capacity, increased energy costs, and premature failure of the unit.

Annual flushing allows homeowners to effectively manage sediment build-up, particularly in areas with hard water, where mineral deposits can accumulate more quickly. In addition to maintaining efficiency, this practice can help extend the lifespan of the water heater, potentially saving homeowners money on repairs or replacements in the long run.

While flushing more frequently may be beneficial in areas with exceptionally hard water, an annual schedule is generally sufficient for most households. Other options, such as flushing every two years or less frequently, could lead to more significant build-up, which could impair the unit’s performance and safety over time.
