The Dangers Of A Faulty Expansion Tank

A failing water heater expansion tank can lead to numerous dangerous situations, including:

  • Failed Parts – A failing thermal expansion tank can lead to other critical parts failing. These parts can include the flu, the tank itself, the fittings, and the connectors.
  • Collapsed Flu – If a failed thermal expansion tank has caused the flu system to collapse or fail, it can expose everyone in your building to poisonous gases such as carbon monoxide (CO).
