cross-connection
Unauthorized plumbing junction
A cross-connection is a physical link between two otherwise separate systems, especially in plumbing where a potable water supply connects to a non-potable source, creating contamination risk.
The term extends to any unauthorized or inadvertent connection between systems that should remain isolated, such as electrical circuits or communication networks.
The inspector found a cross-connection between the irrigation system and the drinking water line.
Backflow preventers are commonly installed to protect against hazards from cross-connections.
