Understanding Backflow

Backflow occurs when water flows in the opposite direction of its intended path, potentially introducing contaminants into your clean water supply. This can happen due to:

Changes in water pressure

Backflow can occur when there are sudden drops in water pressure, causing contaminated water to reverse into your clean water supply.

Plumbing system failures

If your plumbing system fails or is improperly maintained, it can create conditions for backflow to occur.

Cross-connections between potable and non-potable water systems

Backflow often happens when there's a connection between clean water and sources like irrigation or sewage, allowing contaminants to enter the water supply.
