Why is it that FDNY uses hard suction hoses to hook up to hydrants and in New jersey we use 5in and 4in hoses to hook up to hydrants?

Why do you use six small diameter soft suctions connections? Or are these only for the old units? There's no way I can see that you could utilize the of 2000gpm of the new pumpers with such small lines to the hydrant. I'm also assuming that's why you have 6 inch drafting connections so you can use and test the pumps at full capacity as required by NFPA.mac8146 said:In FDNY we use 10 foot soft suction 4 1/2 fitting 3" diameter hose size, 50 foot 3 1/2 fitting with 3" diameter or the 35 foot 4 1/2 fitting with 5" diameter yellow hose. That is basically all that is available. The old hard suctions are being phased out and newer pumpers carry 3 6" soft suctions for drafting only, with all the above for hydrants.
mac8146 said:OK clarification, the hydrant connections mentioned are 10 foot 35 foot and 50 foot soft suctions, the hard suctions were used for both hydrants and drafting. The hard suctions were required to be used by second alarm companies or greater to get max flow from hydrants. These hard suctions were used when drafting from rivers ponds lakes or whatever source used. The newer rigs dont have the old traditional hard suctions. The drafting suctions of today are 6" and not compatible with hydrants 4 1/2 threads. I hope i have cleared this up.

mac8146 said:Yes it is 4 1/2 threads with 3 1/2 soft hose.
I asked the same question quite awhile ago and never got an answer. There's no way they will get the entire rated flow of 2000gpm from the new engines with that size of supply hose.HAZ-MAT 1 said:Why so small? ???mac8146 said:Yes it is 4 1/2 threads with 3 1/2 soft hose.
