Yes, the bottom of a hot water heater is one of the most common areas to rust out and fail. Because heavy mineral sediment and moisture settle at the bottom of the storage tank, and because heat is applied directly to the lower tank base by burners or lower elements, corrosive chemical reactions concentrate heavily in this zone. Once the sacrificial anode rod is depleted, the bottom steel walls corrode through, resulting in unrepairable leaks and structural failure. Verification: Inspect the base of your water heater tank regularly for rust streaks or dampness.
