A backflow preventer is a mechanical device that prevents used water from re-entering and potentially contaminating your drinking water. Not all backflow preventers sold locally are approved for use in Fort Collins. Please ask your supplier for information. Backflow preventers must be tested by certified testers for proper operation upon installation, repair, replacement and at least once every three years. All of the devices should be protected from freezing by installing a shut-off valve with a drain just above ground level to allow the piping to drain.
Higher flows can damage the meter.
Contact Fort Collins Utilities for information regarding flows for larger meters. All installation and system testing requirements must be followed. Upon request, Fort Collins Utilities will test backflow preventers installed by homeowners at the time of installation. Larger connections may be installed downstream of the assembly. Manufacturers of backflow preventers do not recommend blowing out a home irrigation system through the backflow preventer as this could cause damage.
