How can I effectively flush out a water heater to maintain its performance and efficiency?

To effectively flush out a water heater and maintain its performance and efficiency, follow these steps: Turn off the power or gas supply to the heater, connect a hose to the drain valve at the bottom of the tank, open the valve to drain the water, flush out any sediment by letting water run through the tank, close the valve, refill the tank, and turn the power or gas supply back on. Repeat this process annually to keep your water heater working well.
