a connection between the public drinking water supply and a non potable source which may affect the quality of the drinking water
a direct arrangement of a piping line which allows the potable water supply to be connected to a line which contains a contaminant
a link or channel that allows a nonpotable substance, such as wastewater, to come in contact with a potable water supply
a link or structural arrangement where potable water in a distribution system can be exposed to unwanted contaminants
a permanent or temporary piping arrangement which can allow your drinking water to contaminated if a backflow condition occurs
a physical connection between a potable (drinkable) water supply and a source of contamination or pollution
a physical interconnection between the drinking water and possible sources of contaminated water
a potential connection between a drinking water pipe and a polluted source
Situation whereby two separate water sources may combine due to improper plumbing configurations.
Any situation which allows contact between potable water and sewage or water which is not safe to drink.
Any actual or potential connection between a drinking (potable) water system and an unapproved water supply or other source of contamination.
Any actual or potential connection between a drinking water system and any other source or system through which it is possible to introduce any used water, industrial fluid, gas or substance other than intended for drinking water. Category: Public Works
A connection between a drinking (potable) water system and an unapproved water supply. For example, if you have a pump moving irrigation water from a pond and hook it into the drinking water system either to augment the sprinklers, or even just to supply potable water for the irrigation pump seal, a cross connection or mixing between the two water systems can occur. This mixing may lead to contamination of the drinking water system.
1. A physical connection through which the quality of processed water could be degraded.
"Cross connection" means any connection or arrangement, physical or otherwise, between a potable water supply system and any plumbing fixture, or tank, receptacle, equipment, or device through which it may be possible for nonpotable, used, unclean, polluted, or contaminated water or other substance to enter any part of such potable water system under any condition.
Line connecting two piping systems.
A direct link between a potable water system and a non-potable water system, which permits undesirable substances to be drawn into the potable water.
Any physical connection or arrangement between potable water and any source of contamination.
Any physical connection or arrangement between two otherwise separate piping systems, one of which contains potable water and the other either water of unknown or questionable safety or steam, gas, or chemical whereby there may be a flow from one system to the other, the direction of flow depending on the pressure differential between the two systems.
