This is a training scenario for how we get a large amount of water to your apparatus' pump - greater than 500 gpm.
Locally we call this a big fire hookup. I think in other localities you might refer to it as hooking up solid, or making big water.
I wanted to share this training scenario with you. Hope you enjoy it!
The biggest issue here is knowing your hydrants. If the hydrant is a red cap 0-499 gpm hydrant no matter how many lines you hook to it you won't get more than 499 pgm out of the hydrant.
I am a big fan of marking hydrants by color coding the hydrant caps. My current FD carries 2 - 2 1/2 inch hydrant gates in our hydrant bag and tap each hydrant with LDH and then put the gates on the remaining discharges.
I agree, thanks for pointing that out!
The recommendation for hydrant color coding is found in NFPA 291: Recommended Practices for Fire Flow Testing and Marking of Hydrants, you will find the color coding requirements in 22.214.171.124
A summary of hydrant classifications are:
Class AA - Light Blue - 1,500 GPM or greater
Class A - Green - 1,000 - 1,499 GPM
Class B - Orange - 500 - 999 GPM
Class C - Red - 499 GPM or less
