I don't want to re-ignite the flaming that started on this topic, but I am curious. Do any CFD engines carry hard suction? Beyond that, are CFD engine operators trained in drafting? I know that there's a small tanker at the 18's at Lunken, but does it carry a dump tank? Or, does it operate in nurse mode with an engine? Going one step further, what is the typical booster tank size on CFD engines?
Are there even any large areas in CFD's response area without easy access to hydrants? The only places that come to mind are the interstates - for large truck fires.
Thanks.

Engine 7 carries 2 sections of hard suction.The water tanker also has 2 sections. E-18's house had, until recently, a dozen or so sections of hard suction. During the flood of '97, E-3 carried 2 sections.
Also I remember that part of the contingency plan for the big earthquake was for E-3 to draft water from the public landing & pump into 5" hose, which was to be laid up from the river thru downtown.
The CFD water tanker is unreliable in an emergency operation. The inside is rusted so bad that when you open the discharge valves, the intake screen of the pumper you're supplying gets completely clogged with rust.
Here's a question that an old CFD engineer, promoted to lieutenant, used to sharpshoot us youngsters with: How can you draft without using hard suction? Clue: You have to have an older style pumper.

Whistleblower, I doubt this is the technique you're thinking of, but one option would be to "jet" water into a length of 5" or other large diameter soft suction. You'd have to have a static source, e.g. pond, dump tank, etc. that's at nearly the same level as your engine. You'd run an 1 3/4" so that it discharged into the 5" - straight down the length of the hose. It will pull a fair bit of water along with it. I've used this technique to go from one dump tank to another - don't know how far it would work.
Do the engines that carry hard suction also carry strainers? I'd hate to think of drafting out of the river without one.

I'm curious to know how you draft without hard suction too! So, when do we get the answer?
Also, why does only Engine 7 carry hard sleeves? If it has to do with the possibility of pump from the beautiful Ohio, shouldn't Engines 3, 14, 17, 37, 50, etc. being carrying it?
Can anyone tell me when the last time CFD did draft at a fire was?

Sorry to keep anyone guessing about how to draft without using hard suction. I was out of the country for awhile.
Remember the clue: You have to have an old style pumper. That would be one with a booster reel, with 1" hose.
You start by removing the nozzle from the booster line & sticking the open butt into whatever you're drafting from. Then engage the pumps with the transmission in reverse. Attach a line to the intake & theoretically you'll have water!
It's the same principle as backflushing which we have to do every time we use the CF&D's Water tanker.
Someone asked "why don't all the CFD engines that run along the Ohio River carry hard suction?"
I really don't think they need to carry it, just have it in quarters for use during floods. Every Company should be issued 2 sections & they could throw them up in the hose bed if needed.
I haven't seen a strainer in a long time. You're right. That should be part of the equipment.
I'm sure there have been incidences where the CFD has drafted water for an actual fire within the last 30 years. The only story that I can recall of such an event, was the story I heard from my father. He remembered a fire at the brick apartment building in the 2500 block of Hackberry. This was during the 1937 flood. Dad told me that they (CFD) relayed water all the way from the river, up the hill, to that building! I think Dad said it was a 3 Alarm.

Whistleblower, Hmmm, never would have thought of that. I bet that drafting through 1-200' of 1" booster line wouldn't get you much water. This might be one of the times when calling a department that drafts regularly might be a good choice, especially in an area far from the river that had a water main break.

You're right. The application was never intended to be a practical evolution, just something for wannabe engineers.
