Why not just snug it up without the extra steps of shutting down and depressurizing? Maybe that's Tech 2 and Cave 2.Occasionally it’s very useful we’ve had a hose work loose like 600ft back in peacock swimming in and it just started leaking a bit. Stoped for a second shut the valve down and depressurized the reg snugged the hose up and carried on diving total non event.
This is stuff that is taught at the Tech 1 and Cave 1 level in gue.
