at my company im thinking about going to 2" hose on the highrise pack for less friction loss but easier to move around then 2 1/2, i was wondering if anyone is using it and how they feel about it, right now we are using 1 3/4,  thanks for your help.

your crazy if you want 2 inch on a high rise pack...in my opinion....how much friction are you actually losing that you want to do this...is it enough that is going to make a big enough difference for the little bit of extra strain on your guys running it

Buy a few sections of 2 inch and test out what you are saying.   Charge this line and drag it all through your station and engine room.  Then get some ben gay and tylenol and rerack your 1 3/4 and realize some things only look good on paper.

I will have to agree with you on the 2" or Duece and a half...  We are in the same boat of up grading from 1 3/4 to 2 1/2 w/ a smooth bore...  You can find tons of research already done on the net to support it...  There are alot of findings that stand pipes before 92 or 93 will not even get you enough pressure with a 1 3/4 line if needed...  There is a single roll you can do with the 2 1/2 that will fit on the back of your air pack...  Leaves your hands free to carry tools...  with four guys you 200 ft of hose....  I will see if I can find the link on how to roll it and post it in a few days...  There is a good video on U Tube on deploying it..  If set up right it will feed right through the door!  Best of luck...  Do a little research and it will speak for itself!

NFPA #14 states [I] “It is very important that fire departments choose an appropriate nozzle type for their standpipe fire-fighting operations. Combination Fog, Constant Pressure, (Automatic) type spray nozzles should not be used for standpipe operations because many of this type require a minimum of 100 psi of pressure at the nozzle inlet to produce a reasonably effective fire stream. In standpipe operations hose friction loss might prevent the delivery of 100 psi to the nozzle. In high-rise standpipe systems with pressure reducing hose valves, the fire department has little or no control over hose valve outlet pressure.” (NFPA #14, Standpipe and Hose Systems, A-5-7.)[I

2 1/2" line makes a great combination to this because it is a low pressure high volume line....

with proper technique, you can still get protection from a smoothbore nozzle.  you may obviously not have fog capabilities,  but you're technique in extinquishment will give you the protection you need.

If your first on scene I wouldn't use them as the initial resource.  Maybe get them deployed as a back-up and if your arrival is an additional resource.  (lets us know what you come-up with)
