We have found the most efficient means to convey this important information to our engine companies is to paint the hydrant tops and caps using standardized color codes. These colors give us a reasonably accurate picture as to how the hydrant should perform.

2025年1月26日 · Each color represents a different flow rate, typically measured in gallons per minute (GPM).
