My department uses 150' 1.75" preconnects on all apparatus and the Tower has an additional 150' 2.5" preconnect. Our Engine/Tanker also has a Skid Load (200' 3" to a gated wye then 150' of 1.5) for rural structure fires.

We use 1 3/4" preconnects. We did use a combo of 1 1/2" and 1 3/4" but the 1 1/2" was phased out.

You guys want everyone else to quote a source. I gave them to you - it's black and white in NFPA 72, Factory Mutual fire test reports, NIST reports, etc. You don't mention one source I can go to. Like I said, practice what you preach.
Let's see some sources. Give us some real sources that we can go to and that will verify what you say.
I gave you actual sources of the data. You don't even make mention of those sources and just start making unsubstantiated comments.
First, acknowledge the sources I quoted and either recognize their legitimacy or refute them with real data or some other source.
Second, if you are then going to make different claims - give us the source of your data/information.
There's a sign in the testing lab I work next to. It says "1 test is worth a 1000 expert opinions."
I'm not interested in your opinion of fire growth. If you've got real data or a recognized source, let's see it.

We have gone to using 2" almost exclusively. We have found that while the 1 3/4" is more manuverable, the knock down potential of the 2" with a nozzle setting of 150 gpm is quicker. We run both sizes on our engines and our quint.

Sources both NFPA Fire Protection Handbook and Almanac. Oh, and real life, everyone on this forum knows fires do not double every 30 seconds, it isn't true.

1.75" with a TFT auto nozzle is a very workable line. We use it on all attacks(except for that big fire that may happen once a year). We flow at 150psi as SOP. Some guys like a little less pressure, but 150psi feels just right for me.
