Water heaters typically last 8–12 years for conventional tanks and longer for well-maintained tankless units. Recognizing the signs of failure early can prevent a cold shower (or a flooded basement).
Common Warning Signs
- Age: If the unit is over 10–12 years old and problems are increasing, replacement is often more economical than repeated repairs.
- Rusty or discolored water: Especially when it appears only from the hot side, this can indicate internal tank corrosion.
- Leaking from the tank: A leak at the base or from the tank body usually means the tank itself has failed and needs replacement.
- Strange noises: Popping, rumbling, or banging can signal sediment buildup that reduces efficiency and stresses the unit.
- Inconsistent or insufficient hot water: If recovery time is poor or you run out of hot water faster than before, the heating elements, thermostat, or tank may be failing.
- Higher energy bills: An aging unit often works harder and costs more to operate.
Repair vs. Replace
We evaluate the age, condition, and cost of parts versus a new efficient unit. In many East Lansing homes, upgrading to a modern high-efficiency tank or tankless system pays for itself over time through lower energy use and fewer service calls.
