5 Signs Your Heater Needs Repair
Don’t wait until you have no hot water at all. Catching these signs early can save you from a complete system failure:
- Cold Water: The most obvious sign—a complete lack of hot water, or water that only stays warm for a short time.
- Rust-Colored Water: Sediment and corrosion inside the tank is breaking down and mixing with your hot water supply.
- Rumbling or Knocking Sounds: Loud noises from the tank are often caused by excessive mineral scale or sediment buildup.
- Sulphur Odor: A "rotten egg" smell usually indicates a high concentration of bacteria inside the tank.
- Small Leaks: Even a slow drip from the tank base or fittings needs immediate attention to prevent major failure.
