is it just me or does it seem that alot of todays younger guys are not choosing the proper line for the task at hand i know alot of departments mine included has sops on when to deploy the big line are people not wanting to waste the time with putting a 2 1/2" line in service
Look at this video Vic posted. They saved half of that house is a 1 1/2" hose line. If you watch the whole video they show the shots of the rear of the house from after. There was a lot saved there due to the quick and aggressive tactics.
It can be done if you know what you are doing. I volunteer at this department(Prince George's County, MD) and work full time in DC. We are very efficient with out 1 1/2" hose lines. We know what we are doing because we pull them literally every day. I pull a line for every box alarm and usually run several every tour. It may not work for you, but it does for some people.
