Backflow Prevention for Lawn Sprinkler Systems

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

• All sprinkler systems in Fort Collins must be equipped with an approved backflow preventer.
• To ensure compliance with City regulations, have a certified tester check your backflow preventer at least every three years.
• 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 piping and protect your backflow preventer from freezing.
