Explanation:

Understanding Cross-Connections


A cross-connection refers to a link between a potable water system and a nonpotable water system. This situation can create serious health risks, as it may allow contaminants from the nonpotable system to enter the drinking water supply.


For example, if a garden hose is submerged in a swimming pool, and the water pressure drops, contaminated water from the pool can be siphoned back into the drinking water system, leading to potential health hazards.


Cross-connections are particularly relevant in plumbing and water safety discussions, emphasizing the need for proper backflow prevention devices to keep drinking water free from pollutants.
