A failing water heater doesn’t always go out with a dramatic splash—most of the time, it gives you warning signs first. The good news? Catching these signs early can mean the difference between a simple repair and a full system replacement.
At Radiant Plumbing & Air Conditioning, we’re here to help you determine whether your water heater is salvageable or if it’s time for an upgrade. Here’s what to watch for:
1. Rusty or Discolored Water
If your hot water looks rusty, murky, or has a strange tint, your water heater may be corroding from the inside. Once the tank begins to rust, there’s no way to reverse it—and it’s only a matter of time before a leak develops.
What to do: If you notice rust-colored water, especially from the hot water taps only, it’s time to call Radiant. We’ll assess whether the issue is inside the water heater or coming from your plumbing system.
2. Your System is Getting Old
Most water heaters last 8-12 years, depending on maintenance. If yours is getting up there in age, there are a few things you can do to extend its lifespan and avoid premature failure:
- Flush the Tank Regularly – Flushing removes sediment buildup that can cause inefficiency and overheating.
- Check & Replace the Anode Rod – This small but mighty component attracts corrosive elements, preventing them from attacking the tank. A fresh anode rod can significantly extend the life of your unit.
- Schedule Annual Maintenance – A professional inspection ensures your water heater is running safely and efficiently.
Not sure how old your water heater is? Check the manufacturer’s label or call Radiant, and we’ll help you figure it out.
3. Loud Noises Coming from the Tank
A water heater should hum quietly in the background, not rumble like an old truck. If you hear popping, banging, or cracking sounds, it’s likely due to sediment buildup at the bottom of the tank.
As sediment accumulates, it hardens and traps water underneath, causing steam bubbles to form and create these noises. Over time, this can lead to:
- Overheating (leading to more wear and tear)
- Reduced efficiency (higher energy bills)
- Cracks or leaks (which usually mean replacement)
What to do: If your water heater is making strange noises, don’t ignore it. A professional flush may solve the problem, but in some cases, replacement is the best option. Radiant can help you decide.
4. Water Leaks Around the Tank
A small leak might seem harmless, but it’s often a sign of a bigger issue. Once a water heater tank starts leaking, there’s no reliable way to repair it—it will only worsen over time.
What to do: If you spot moisture, pooling water, or rust stains near your unit, turn off the water supply and call Radiant immediately. A leaking water heater can quickly lead to water damage and costly repairs.
