Piping shall extend at least 2 inches beyond the last nozzle in each branch line in marine systems to prevent clogging.

Explanation:
In marine clean agent piping, extending the last branch line beyond the final nozzle by a short stub helps prevent clogging by giving a small clearance for flushing, inspection, and potential debris to be kept away from the nozzle exit. Two inches is the minimum specified because it provides enough length for cleaning and purging without altering the nozzle’s discharge characteristics. A shorter extension, like one inch, may not reliably prevent buildup, while longer extensions (three or four inches) aren’t required by the standard and add unnecessary length.
