Your water heater is one of the most essential systems in your home, but it’s easy to forget about it until something goes wrong. Whether you’re dealing with cold showers or rising energy bills, your water heater may be trying to tell you it’s time for a replacement.
At ServiceOne, we help homeowners in Omaha, Dubuque, and surrounding areas stay ahead of costly repairs by spotting early warning signs. If you’re noticing strange noises, inconsistent temperatures, or leaks, they could be signs your water heater is going out.
Here are five key indicators that your water heater may be on its way out:
1. Inconsistent Water Temperature
If you’re constantly adjusting the faucet just to get warm water, or your hot water runs out quicker than it used to, it may be more than just a minor inconvenience. Fluctuating water temperatures often signal a failing heating element or thermostat. While some of these issues can be repaired, repeated problems are a strong sign that your system is nearing the end of its lifespan.
2. Rusty Water or Rust Around the Tank
Brown or rusty water coming from your hot water tap could be a sign of corrosion inside the water heater tank. This is especially concerning if the water looks fine when running cold. Additionally, if you notice rust or corrosion around the tank or at the pipe connections, it's time to act. Once corrosion starts, there's no reversing it, and your water heater could fail suddenly, potentially causing leaks or flooding. This is one of the more visible signs your water heater is going out and shouldn’t be ignored.
3. Strange Noises Coming from the Tank
A little noise is normal, but if your water heater is rumbling, popping, or making banging sounds, it’s likely due to sediment buildup. Over time, minerals from hard water settle at the bottom of the tank and harden. This makes your water heater work harder, reducing efficiency and putting strain on the system. These sounds are more than just annoying—they're often a warning that your water heater is nearing failure.
4. Leaks or Pooled Water Around the Tank
Any moisture around the base of your water heater should be taken seriously. Leaks may come from a crack in the tank or from loose connections, but either way, they shouldn’t be ignored. Water damage from a leaking tank can lead to costly repairs to flooring, walls, and personal belongings. If you’re seeing puddles or drips near your unit, it could be one of the clearest signs your water heater is going out.
5. Age of the Water Heater
Most traditional tank water heaters last about 8–12 years. If your unit is over a decade old and you’re starting to notice any of the above issues, it may be more cost-effective to replace it than to repair it. Newer models are more energy-efficient, which means you'll also save money on utility bills in the long run.
