Third, maybe I was doing something wrong, but neither me nor my buddy were able to 'crimp' the hose. And it certainly is not as easy as suggested to grab the house like you grab a hose normally. I tried for several seconds to reach it and it was moving too fast. Once my buddy got it, she tried to no avail to crimp it. I tried to both fold it over it and hold my thumb over the end. Air continued to escape at a rapid pace.
No, you weren't doing anything "wrong." Very few instructors teach hose crimping, and I doubt yours did.
But here's the procedure:
First, you have to get your hands on the hose - it's only flailing at the loose end; the other end is attached to the first stage and isn't moving, and that's where you grab it first, then move your hand along it until you have enough hose to work with.
Fold the hose back on itself and while holding the end of the hose against the hose with one hand, run your other hand down the doubled hose, like tightening a noose, until you have the doubled "end" in your hand. Squeeze
tightly to crimp. It is not easy and you have to squeeze hard, but you
can do it. I've had girls who had to use both hands when they got to the squeezing-to-crimp part, but they could do it.
The hose is stiff and it's got ~150 psi of air pressure in it (no way can you hold that back with a thumb) so crimping it is a
forceful maneuver, and , as I mentioned, you don't want to practice on a good hose as it's bad for it. As I said, very few instructors teach it, and I don't know any that have students actually do it because of the damage it does to the hose - they'd have to have a dedicated "sacrificial" hose to do it with. I talk about it, but rarely have the opportunity to let folks do it "hands on."
Please don't think I'm criticizing
you when I say you could have crimped the hose. You weren't trained to do it... You did what you were trained to do, that worked, and everybody's ok... and that's a good thing, a good bottom line.
