Discharge into the drinking water system occurs when water is no longer used. Backflow occurs by accident or due to poor connections to pipes or "faulty junctions".

A faulty junction is a connection between a drinking water system and any other source of water, and may occur in the following places:

  • Secondary water supply (pond water)
  • Cooling towers
  • Sprinkler systems
  • Boiler systems
  • Laboratory equipment (medical and industrial)
  • Lawn sprinkler systems
  • Solar water heaters
  • pools
  • Water recirculation devices
  • Environmentally friendly or environmentally friendly building systems
  • Treatment tanks

Why is repression a problem?

When backflows occur, contaminants such as chemicals, pathogens, and non-drinking water can be sucked into the city's water system, contaminating drinking water.

This dangerous dangerous situation can be avoided by properly installing a backflow preventer. The facility is relatively inexpensive and protects the drinking water supply.
