What Causes Backflow?

Typically, pressure differential keeps clean water flowing from the local water agency to your home, and then wastewater from your home to your local sewage system. But when pressure increases at the receiving end of the system (back siphonage) or decreases at the source (back pressure), it can cause the water to reverse direction. Your wastewater can enter the general water supply, or your wastewater can flow back into your home.

Water flow can reverse by:

  • Boilers, sprinklers, or power washing tools
  • A broken water main
  • Firefighting siphoning off a large quantity of water
