Your water heater works quietly in the background every single day — until it doesn’t. When a water heater fails unexpectedly, it can mean cold showers, water damage from a burst tank, or a flooded utility room. The good news? Most water heaters give warning signs well before they fail completely.

Here are five signs Salem-area homeowners should watch for, and what to do when you spot them.

1. Your Water Heater Is Over 10 Years Old

Most traditional tank water heaters are designed to last 8–12 years. If yours is approaching or past that range, it’s time to start planning for a replacement — even if it’s still working.

💡 Pro TipYou can find your water heater's age by looking at the serial number on the unit. The first two digits typically represent the year of manufacture.

2. Rusty or Discolored Hot Water

If you’re noticing orange, brown, or reddish water coming from your hot tap (but not the cold), the inside of your water heater tank is likely corroding. This is a serious warning sign — rust in the tank usually means failure is imminent.

3. Rumbling, Popping, or Banging Sounds

As water heaters age, sediment builds up at the bottom of the tank. When it heats up, it makes loud noises. This buildup:

  • Forces the unit to work harder and use more energy
  • Causes micro-fractures and leaks over time
  • Dramatically shortens the remaining lifespan of the tank
⚠️ When to Act FastIf you hear loud banging combined with visible water around the base of the unit, call a plumber immediately.

4. Water Pooling Around the Base of the Tank

Even a small amount of moisture around your water heater warrants a closer look. A cracked tank cannot be repaired and the unit will need to be replaced.

5. Rising Energy Bills Without Explanation

An aging water heater has to work much harder to heat the same amount of water. A new high-efficiency unit can cut water heating costs by 20–30%.

What’s the Right Replacement for Your Home?

  • Traditional tank water heaters — most affordable upfront, great for larger households
  • Tankless (on-demand) water heaters — energy-efficient, endless hot water, higher upfront cost
  • Heat pump water heaters — highly efficient, best for garages or utility rooms
