What is a primary concern with cross connections?

Cross connections are direct links between a potable water supply and a source of contamination. The primary concern with cross connections is the risk of contamination, which can occur when non-potable substances, such as chemicals, sewage, or other pollutants, enter the drinking water supply. This can lead to serious health hazards for individuals consuming the contaminated water, potentially causing illness or the spread of disease.

Proper backflow prevention measures are critical in plumbing systems to ensure that potable water remains safe for consumption. Regulations and guidelines typically emphasize the necessity of identifying and eliminating cross connections to protect public health and prevent contamination incidents. This concern over contamination extends not just to individual health but also to the integrity of community water systems.
