Reg Failures

[Teller]

Other than a free flow is there anything else that can stop a reg from working properly on a dive?

Water in a tank making it wet (and nasty) to breathe from.
Rust from tank clogging filter.
Faceplate falling off.
Mouthpiece comming off.
Exhaust valve not sealing properly.
Inhilation valve not sealing properly.
Demand lever breaking or dislodged.
Spring breaking in either 1st or 2nd stage.
Cracked/damaged 2nd stage.
Poor swage comes away from hose.
2nd stage comes unscrewed from hose.
J valve knocked down by mistake.
Tank valve not fully open.
.......these will not cause a ff.
Most other problems will result in ff.

Regulator hose fails...
O-ring extrudes.
Shop monkey forgot to screw the hose in tight enough to the first stage.
The second stage is cracked and causes major leakage of water on inhalation.
First Stage seat fails and causes freeflow.


I've personally seen all of these happen.. as well as others..

Misassembly resulting in parts changing position or falling apart due to improperly torqued connections.

All these items are under the tittle of poor maintainence/operator error.

I seem to remember a improperly installed poppet on a trip you were on that resulted in a complete failure to deliver air.... MK10B/G250 if I remember right. Unit just had come from service and the owner hadn't tested it in the dog water bowl (or anywhere else except at 95 feet deep.....).

To be more specific I am trying to understand how a reg can fail and not free flow. Many people say that a drawback to SM is that if one reg fails you just lost half of your gas however it is very easy to feather the valve on a cylinder in SM configuration if the reg free flows. So what I want to understand is how can my reg fail and not free flow with proper maintenance?
