When you start talking about friction loss and stuff like that and water pressure, thats over my head, i will admit if i was the operator i would be what they call a lever puller, cause i dont know how to calculate friction loss.

And when they start lifting off the ground, throttle back, right? lol Nothing wrong with that. I have always heard that ballpark is just fine to get started and that no one can tell a difference of five to ten pounds of pressure. I guarantee that someone will tell you to increase or decrease when needed. The math comes into play on long and/or large incidents and who wants to be stuck on the pump panel then? But try to get into a CDPO class because you'll learn a whole lot, even if you do tend to forget the math. Thanks for having this group and replying to my discussion.

That's what I like about our '06 Silverfox.The pumps are electronically controlled. Put them in PSI mode and the truck just about pumps itself, pretty hard for even me to screw up!:)

Ours also have an electronic controller but like everything else, we have to still be vigilant. Ive seen it come close to cavitating and shoot the pressure up to 200 and things like that. It would be nice to have it totally automatic where only things like hose length and elevation would need to be entered. Im sure nozzles used will already be programmed. Im sure the future technology will make it foolproof. With manual overrides, of course.

I know Fire-Trucks now are like miles of wires, were as you take my stations original 1958 american-lefrance, it's nothing but the real deal of line, and levers, and the pump, LOL
