Backflow happens when water pressure changes and pulls dirty water into the clean supply. This can introduce pesticides, chemicals, sewage, and bacteria into drinking water.
Common causes of backflow include:
✅ Burst pipes
✅ Hydrant use by firefighters
✅ Sudden drops in water pressure
✅ Incorrect plumbing connections
Without a proper backflow prevention system, your business risks health code violations, legal fines, and customer safety concerns.
Backflow Prevention Devices: How They Work
To stop contamination, backflow preventers are installed on commercial water lines. These devices allow clean water to flow in one direction while blocking anything from coming back.
There are two main types of backflow preventers:
🔹 Reduced Pressure Zone (RPZ) Valve – Used in high-risk areas like restaurants and industrial sites.
🔹 Double Check Valve (DCV) Assembly – Common in commercial buildings with fire sprinkler systems.
Without these devices, your business could be at risk of spreading contaminated water through faucets, dishwashers, and ice machines.
