In addition to the colors specified by the NFPA, many municipalities rely on their own systems to communicate information to their local fire companies and water management organizations. For example, some utilities color-code the bonnet to indicate the size of the water main the hydrant is connected to. While Mueller Co.

Pitot pressure: Measured at the outlet (s) with the hydrant on, helps determine the actual flow rate and efficiency of the hydrant. Are fire hydrants color coded?

While they are traditionally red, these days they are also several other colors as well. These colors are significant and tell the fire department a lot about the hydrant. Discover the essential fire hydrant color code system that helps firefighters identify water flow capacity and sources during emergencies.
Understanding Fire Hydrant Color Codes The National Fire Protection Association (NFPA) provides a standard, NFPA 291, for color-coding fire hydrants. This system primarily uses the color of the hydrant's top or nozzle caps to indicate its water flow capacity in gallons per minute (GPM). Test hydrants annually to ensure proper functioning Any hydrant with a rating under 20 psi should be stenciled in black on the top and nozzle caps with the rated pressure.
