Water Heater Warning Signs: Repair or Replace?

A typical tank water heater lasts roughly 8 to 12 years. Knowing the warning signs helps you replace it on your schedule instead of after it floods the basement.

Rumbling or popping from the tank

Sediment builds up on the bottom of the tank and traps water that boils and pops. It lowers efficiency and stresses the tank. Flushing can help on a younger unit.

Rusty or discolored hot water

If only the hot side is rusty, the tank or its anode rod may be corroding. That is often a sign the heater is near the end of its life.

Water around the base

A leak from fittings or the relief valve may be repairable. A leak from the tank itself cannot be repaired, and the tank needs to be replaced soon.

Not enough hot water

A failed heating element or thermostat on electric units, or a burner or thermocouple problem on gas units, is often repairable. Persistent shortages in an older heater can mean it is time to replace.

Repair or replace?

As a rule of thumb, repair a young heater with a simple part failure, and replace one that is leaking from the tank, is over ten years old or needs repeated repairs. Ask for both options and their costs.
