Backflow Prevention

  • All sprinkler systems must be equipped with an approved backflow preventer.

A properly installed and approved backflow preventer keeps water that may be contaminated with pesticides and fertilizers from re-entering your home through your sprinkler system.

  • All sprinkler systems must be equipped with an approved backflow preventer.
  • Have a certified tester check your backflow preventer at least every three years to ensure compliance with City of Fort Collins regulations.
  • Not all backflow preventers sold locally are approved for use in Fort Collins. Ask your supplier for information.
  • Install a shut-off valve with a drain just above ground level to drain the pipes and protect your backflow preventer from freezing.
