Understanding Backflow Prevention in Louisville

Backflow prevention is fundamentally about protecting Louisville’s water supply from contamination. When water pressure drops in the main supply lines—which can happen during water main breaks, fire hydrant use, or high demand periods—it creates conditions where water can flow backward from buildings and facilities into the public water system. This reverse flow can potentially carry chemicals, bacteria, and other contaminants into the drinking water supply, posing serious public health risks.

• Cross-Connection Hazards: Areas where potable water systems connect to non-potable sources, creating potential contamination points if backflow occurs.
• Backpressure Backflow: Occurs when downstream pressure exceeds supply pressure, forcing water backward through the system.
• Backsiphonage: Happens when negative pressure creates a vacuum effect, pulling potentially contaminated water back into the clean supply.
• Health Implications: Contamination can introduce pathogens, chemicals, and other hazardous substances into drinking water.
• Property Protection: Beyond public health, proper backflow prevention protects a facility’s internal plumbing systems from damage and contamination.
