¿Qué es la conexión cruzada?
Las conexiones cruzadas existen siempre que el sistema de agua potable está o podría estar conectado a cualquier fuente no potable (artefactos o equipos de plomería utilizados en cualquier sistema de plomería). Los contaminantes o los contaminantes pueden ingresar al sistema de agua potable a través de una conexión cruzada incontrolada cuando se produce un reflujo.
Where are Cross-Connections Found?
Cross-connections are found in all plumbing systems. It is important that each cross-connection be identified and evaluated as to the type of back-flow protection required to protect the drinking water supply. Some plumbing fixtures have built-in back-flow protection in the form of a physical air gap. However, most cross connections will need to be controlled through the installation of an approved mechanical back-flow prevention device or assembly. Some common cross-connections found in plumbing and water systems include:
-Wash basins & service sinks
-Hose bibs
-Irrigation sprinkler systems
-Auxiliary water supplies
-Swimming pools/hot tubs
-Photo developing equipment
-Solar heat systems
-Boilers
-Fire sprinkler systems
-Water re-circulating systems
