Top 5 Signs Your Water Heater Is About to Fail (And What to Do About It)

Your water heater doesn’t usually go out without warning—but if you know what to look for, you can catch a problem before it becomes a cold shower emergency.

Here are 5 signs your water heater might be ready to retire:

1. Inconsistent Water Temperature

If your water goes from hot to cold within minutes (or never really gets hot), it may be a failing heating element or sediment buildup in the tank.

2. Strange Noises

Hearing banging, popping, or rumbling? That’s usually caused by hardened sediment heating up and rattling around. It reduces efficiency and shortens your heater’s life.

3. Rusty or Discolored Water

Brown or red-tinted water from your hot taps can signal corrosion in your water heater tank—especially if it only affects the hot water.

4. Leaks Around the Base

Even small drips or puddles near the bottom of your tank are red flags. Over time, pressure or corrosion can cause tiny cracks to form and worsen.

5. Age (8+ Years Old)

Most standard water heaters last 8–12 years. If yours is pushing past its prime, it might be time to start planning a replacement—before it forces your hand.
