- A failed HP hose will take a while to empty
the tank because there's a pinhole sized
orifice in the first stage just behind the
HP port. A failed LP hose, on the other hand,
will empty your tank in very short order. I
ran an experiment a while back on both cases.
IIRC, I removed the HP hose from the first
stage, and the tank dropped 150 PSI/minute.
I removed the LP hose, and it dropped 1500
PSI/minute (and wanted to take off across
the driveway).
- I've had two tank/valve O-rings extrude in my
truck, and one of the divers for my boat turned
up with one a couple of weeks ago. None of
these happened in the water, but they could.
- I've recently started diving the long hose on
open circuit, and, if nothing else, for the
first time, I don't have that darn octopus
flopping around, in the way, coming out of the
holder and dragging on the reef. And having
had to donate air a couple of times (to stupid
divers whom I don't dive with any more), I'd
much prefered to have had the long hose to
give them.
- I'm NOT a DIR divers, just steal portions of
their rig.
