Your are correct. 2 men are able to advance 2.5 inch, if they know how do that..

when the nozzles is open, they put their knees on the floor, making a brake at the force vector produces by reaction force of water. if you are operating a 2,5 inch hose, you don't need movility, you need high volume of water.

Our county considers 3 on an engine company "staffed". I'm currently stationed at a rural fire company with 5 paid firemen on a shift. We staff the engine or engine tanker and an ambulance. When I arrived here a year ago, the attack engine had 2, 200' 1 3/4" crosslays with fog nozzles, and a 300' section of 2" with a fog nozzle off the back. I could not believe that we had no option on the engine to move big water in a fire attack. After getting the ok from all the Lt's at the station, my shift and I removed the 2" from the rear and replaced it with 300' 2 1/2" with a smooth bore nozzle. I believe that you need to have options for whatever situation you may be faced with. I agree that 2 1/2" is harder to advance and manage than 1 3/4" but if the fireman know how to handle it and you need more gpm's there is no replacing it!

Why not just use the 1-3/4" line for a big hit line using just one fireman and get a flow of at least 250 GPM. Its great for a under staffed first in unit that needs to get a big hit on a fire. Its easy ,pump 250 psi and sit on it.

True, you can push 250 GPM out of 1 3/4" and I understand what you're saying. But you can flow 400 GPM through 2 1/2" if you want too. I'm just saying it gives you more options to have a greater selection of hose sizes on the apparatus... It is easy to crank it up to 250 PSI for the engine operator. : )

My dept is 4 sq miles, we run 2 ALS/Rescue engines out of one house. We run in the neighborhood between 1400-1500 runs a year, fire and medical. Both engines are set up alike, 2-200ft 1.75 preconnects, 75ft. trashline on the bumper(1.75) A static bed with 400ft of 2.5 with 100ft of 1.5 on it sorta like a hotel pack. The 1.5 can be disconnected for a 2.5 line, we practice advancing stairs etc. In our area we have it all, 5 story high rise, 2 industrial parks, an enclosed shopping mall, you get the picture Brother. We operate 3, 7 person crews, if we are full, 1 company has 4 the other 3. Most of the time due to vacations, 3 per engine. We put our big line in service by getting where we need it, before we think about water in the line, it's a huge knock and very needed in certain situations.

Be Safe!

Let me rephrase that. When manpower is an issue and the 2-1/2" line could present a problem to use because of that, think about getting a high flow 1-3/4" line in service just to get started. By the way their are certain types of 1-3/4" hose that can get 350 gpm on a 200' line with an 1-3/8" tip.
