In a place like Key West, where sea level and water usage present unique challenges, having a functioning backflow prevention system is critical for protecting public and private water supplies.
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 — allowing contaminated water to enter the clean water supply. 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.
Our licensed team can recommend the best device for your needs based on usage, risk, and compliance requirements. 💡 Learn more on our Plumbing Services page.
