How often should I flush my water heater?

We recommend flushing your water heater annually to remove sediment buildup that can reduce efficiency and shorten its lifespan. However, the optimal frequency depends on several factors:

• Water hardness: Homes with hard water (high mineral content) should flush more frequently, potentially every 6 months, as mineral buildup occurs more rapidly.
• Tank size and household usage: Smaller tanks or homes with higher hot water usage may need more frequent flushing.
• Water heater age: Older units often benefit from more frequent maintenance to extend their remaining service life.
• Signs indicating needed maintenance: Rumbling/popping sounds from the tank, decreasing hot water capacity, or visible sediment in hot water are all signs your water heater needs immediate flushing.

Professional flushing not only removes sediment but also provides an opportunity to inspect the anode rod, pressure relief valve, and other components critical to your water heater's operation and safety.
