What type of backflow prevention device is commonly used in Florida?

In Florida, the type of backflow prevention device that is commonly used is the reduced pressure backflow prevention device. This device is specifically designed to protect potable water supplies from contamination due to backflow, which can occur when there is a drop in pressure in the water supply system, causing non-potable water to siphon back into the potable supply.

The reduced pressure design distinguishes itself by incorporating two check valves, which work together to minimize the potential for backflow while maintaining a pressure differential. This is especially important in areas where irrigation systems are prevalent, as these systems can inadvertently allow contaminants to enter the drinking water supply. The design is effective in situations where there is a higher risk of contamination, such as in commercial settings or environments with complex plumbing systems.

While other devices, such as double-check valves and vacuum breakers, can also serve to prevent backflow, they may not be as universally applicable across varied landscape irrigation needs or as effective in high-risk situations as the reduced pressure backflow prevention device. This makes the reduced pressure device a standard choice for compliance and safety within Florida's water regulations.
