Since 1990, the Florida Building Code has required that residential irrigation systems have a backflow preventer. The state requires that homeowners have their backflow preventers tested every two years by a certified backflow tester, and that water utilities submit annual reports on the compliance status of their customers. The City of St. Cloud Environmental Utilities Department has a Cross Connection Control Program in place, whereas all residential backflows connected to the City's water system are tested and maintained by the City of St. Cloud. Below are a few of the "Frequently Asked Questions", along with the types of devices and the "Standard Details" required by the City. For additional information with regards to backflow requirements, you may contact the City's Backflow Division at 407-957-7114.
