Replacing a water heater on your schedule costs less and is far less disruptive than replacing one after it empties itself onto the floor. Most units give warning first.
1. Hot water runs out faster than it used to
Usually sediment on the bottom of the tank or a failing lower heating element. Both are addressable, but on an older unit it is a signal the tank is aging.
2. Rumbling or popping during heating
That is water boiling beneath a sediment layer. It reduces efficiency and stresses the tank. A flush helps if it is caught early.
3. Rusty or metallic-smelling hot water
Often a spent anode rod. Once the anode is gone, the tank lining itself starts corroding and the clock is running.
4. Moisture around the base
Check whether it is a fitting or the tank body. Fittings can be repaired; a leaking tank cannot, and it should be replaced before it fails completely.
5. Age past ten years
Anchorage's cold incoming water makes heaters work harder than in milder climates. Past a decade, repair costs stop being good value.
6. Repeated pilot or element failures
One repair is normal. A pattern of them usually means the underlying problem is pressure, venting or scale — worth diagnosing properly rather than replacing the same part again.
