I had heard stories about these flags, and now I can confirm that they do exist:
Conditions: +3 F with a -9 wind chill.
According to a friend of mine, the fire hydrant base is colored according to the fire department and the top indicates the water pressure. I’m sure this varies from location to location though.
- Class AA (>1500 gpm) light blue
- Class A (1000-1499 gpm) green
- Class B (500-999 gpm) orange
- Class C (0-499 gpm) red (a.k.a. find a better hydrant)
colors/pressures
I have an even better solution. With the hydrant snorkel, it marks the hydrant (with pressure color) and you can hook to the hydrant and turn it on without digging out the hydrant.

Good idea Ed. In fact, I have already installed hydrant snorkels on all the fire hydrant I have ever seen over the last two decades, so no worries.
