[quote name='phyrngn' post='127336' date='Jul 8 2007, 21:52 ']I was told at one time that DCFD Wagons had 550 feet of 1 3/4" preconnected (and from the looks of some of your pictures, it looks like it)...is this a backup line? What pressures do they pump? I was always told that you couldn't get better than about 100 GPM past 300 feet in 1 3/4" line...
Great shots of DCFD rigs...love to see the business end and how they are all set up. Thanks for sharing![/quote]
DCFD limits choices: one either pulls an 1 ½” or a 2 ½”. The longest preconnected hand line is the 350’ 1 ½” off the back step. The modus operandi for the first-due engine is speed in placing a line in service. A good company can stretch a 350’ and extend it with two “standpipe racks” to create a 550’ line very rapidly, while the larger lines or multiple lines are laid in (it’s happened on occasion and I’m guessing that’s where your 550’ number came from). DC uses 125-GPM CVFSS nozzles for 1 1/2". You can get the GPM in an exotic hose layout – just do the math and don’t exceed 300 PSI engine pressure.
