What Is Backflow?

Backflow happens when water flows the wrong way in a plumbing system, which can let contaminated water get into the clean water supply.

Backflow conditions may occur because of:

  • Sudden pressure changes
  • Water main breaks
  • Back siphonage
  • Back pressure conditions
  • Plumbing system failures
  • Irrigation system cross-connections

Without proper backflow prevention devices, contaminated water from:

  • Irrigation systems
  • Commercial equipment
  • Chemical systems
  • Boilers
  • Fire sprinkler systems
  • Industrial plumbing systems

This water could flow back into the drinking water supply.

Backflow prevention devices block unclean water from getting into the drinking water supply, lowering the risk of illness and plumbing damage.
