What is the primary risk associated with backflow?

The primary risk associated with backflow is health hazards from contaminated water supply. Backflow occurs when water flows in the opposite direction from its intended flow, often due to a loss of pressure in the distribution system. This condition can lead to harmful contaminants, such as bacteria, chemicals, or other pollutants, entering the clean water supply.

When backflow occurs, it poses a significant health risk to consumers who may unwittingly consume contaminated water, potentially leading to serious illnesses or health complications. Protecting the integrity of the water supply is crucial, which is why backflow prevention devices and proper practices are essential in plumbing systems.

While increased operational costs, loss of water pressure, and damaged plumbing infrastructure are also concerns that can arise from backflow situations, they do not directly address the immediate and serious health implications that contaminated water can cause. Hence, the health hazards from contaminated water supply are considered the most critical risk associated with backflow.
