Sediment buildup causing rumbling and slow recovery
Why it happens here
Mirror Lakes water is hard, so calcium and magnesium settle at the bottom of the tank every time it heats. Over three to four years, that layer insulates the water from the burner or element. The tank works harder, makes noise, and recovers slowly.
Our approach
We flush the tank through the drain valve with a pressure gauge, pull the lower element if needed, and clear the sediment. We also check the anode rod and replace it if it is more than half gone. This restores efficiency and quiets the tank.
