In a place like Key West, where sea level and water usage present unique challenges, having a functioning backflow prevention system is critical, especially when combined with annual backflow testing in South Florida.
At Gary’s Plumbing & Fire, we’re certified in backflow prevention testing and installation throughout the Florida Keys. Here’s how to choose the right system and why it matters.
What Is Backflow and Why Should You Care?
Backflow occurs when water flows in the opposite direction — as explained in our guide on what to expect during a professional backflow test in the Florida Keys. This can be caused by:
- Changes in water pressure
- Broken water mains
- Improper irrigation setups
- Fire hydrant use nearby
In Monroe County, backflow prevention devices are required for commercial properties and most multi-family residences.
Types of Backflow Prevention Devices
- Double Check Valve Assemblies (DCVA)
Common for fire lines and some residential systems. Compact and affordable. - Reduced Pressure Zone Assemblies (RPZ)
Offers maximum protection. Ideal for properties with higher contamination risk. - Pressure Vacuum Breakers (PVB)
Often used for lawn irrigation systems.
