5 Signs Your Water Heater Needs Replacement

Your water heater is one of the hardest-working appliances in your home, providing hot water for showers, dishes, laundry, and more. But like all appliances, water heaters have a limited lifespan. Knowing when to replace yours can save you from unexpected breakdowns and potential water damage.

1. Age of Your Water Heater

Most traditional tank water heaters last 8-12 years, while tankless models can last up to 20 years. If your water heater is approaching or exceeding its expected lifespan, it's time to start planning for a replacement. You can find the age of your unit by checking the serial number on the manufacturer's label.

2. Rusty Water or Corrosion

If you notice rust-colored water coming from your hot water taps, or see corrosion on the tank or connections, your water heater may be deteriorating from the inside out. This is a serious warning sign that shouldn't be ignored, as it often precedes a tank failure and potential flooding.

3. Strange Noises

Rumbling, banging, or popping sounds from your water heater indicate sediment buildup at the bottom of the tank. As sediment accumulates and hardens over time, it makes your water heater work less efficiently and can cause damage to the tank itself.

4. Water Leaks Around the Unit

Any water pooling around your water heater is a red flag. While some leaks can be repaired, leaks from the tank itself usually mean it's time for a replacement. Small fractures in the tank will only get worse over time.

5. Inconsistent Water Temperature

If you're experiencing fluctuating water temperatures or can't get enough hot water for normal household use, your water heater may be failing. This could indicate heating element issues, thermostat problems, or general wear and tear.

Don't Wait for a Complete Failure

Replacing a water heater before it fails completely gives you time to research options, compare prices, and schedule installation at your convenience. Waiting for an emergency replacement often means higher costs and the inconvenience of being without hot water.
