Our fire apparatus currently have two or three cross-lays. They are 1-3/4 inch, two of them are 200 feet in length and a 150 feet. We have a couple of progressive firefighters wanting to convert one of the cross-lays to 2-1/2 inch 200 feet. We have flow tested 2-1/2 inch attached to the 1-3/4 inch connection and able to get 325 gpm out of it. Yes, we have a 2-1/2 inch preconnect off the rear but it seems like we (as a department) forget about using it early in a fire and rely to heavily on the 1-3/4 inch cross-lays.
I feel that we should change the cross-lay to include a 2-1/2 inch but we are having heavy opposition from many of the other officers and members of the department.
Wanting to know how many other fire departments out there are using the 2-1/2 inch cross-lay and the reasoning behind it?
