Signs Your Water Heater Is About to Fail

Water heaters rarely fail without warning. Watch for these five signs so you can replace it before it leaks.

Rusty or Discolored Hot Water

If your hot water runs brown or rusty but the cold is clear, corrosion inside the tank is the likely cause β€” and a corroding tank is on borrowed time.

Rumbling or Popping Sounds

Sediment builds up at the bottom of the tank over the years. When it hardens, you'll hear rumbling or popping as the burner heats through it. This makes the unit less efficient and shortens its life.

Water Pooling Around the Base

Any moisture around the base of the tank is a red flag. A small leak today often becomes a flooded utility room tomorrow.

Age and Inconsistent Temperatures

Most tank water heaters last 8–12 years. If yours is in that range and the hot water is running out faster or fluctuating, it's time to plan a replacement before it fails on its own schedule.
