How can backflow be prevented?
  • Be aware of and eliminate cross-connections.
  • Maintain air-gaps. Do not submerge hoses or place them where they could become submerged.
  • Do not create a connection between an auxiliary water system (i.e., well, body of water, pond) and the water supply plumbing.
  • Use hose bib vacuum breakers on all fixtures (i.e., hose connections in the laundry room, outside, and on sinks).
  • Install approved, testable backflow prevention assemblies on commercial irrigation systems.
