All piping conveying non-potable water shall be permanently identified by a continuous _______________ coloring so that the piping is readily distinguishable from piping carrying potable water.

blue
green
purple
yellow

The correct answer is: purple

Piping conveying non-potable water must be clearly distinguished from piping carrying potable water to prevent any cross-connections or contamination. According to the Illinois Plumbing Code, non-potable water piping should be identified by a continuous purple coloring. Purple is the standard color used to designate non-potable water piping in plumbing systems. This helps plumbers and inspectors easily differentiate between potable and non-potable water systems, ensuring the safety and integrity of the water supply. The other options, such as blue, green, and yellow, are not suitable for identifying non-potable water piping according to Illinois Plumbing Code standards.
