Question What causes a diaphragm to break like this?

Took my reg in for services, got this pic back [sad regulator noises]. What causes a diaphragm to break like this?

Could be sheer age but is far more likely the result of a clumsy, knuckle-walking tech, during a previous servicing, with a pointy o-ring remover and nothing to lose . . .

That’s kinda what I came up with, but the reg is only a year old and this is its first services.

If it was breathing before you brought it in I'd push for a good explanation as to what happened.

if you know it was working and holding a seal before you took it in, it got torn during servicing. You can see the point on the left where the tears start from.

Yep.

thanks all, this shop came pretty highly recommended, but we’re still working through a bit of a language barrier. This puts some context to why he said he’d lend me his personal reg for some training dives I have to do in a couple weeks.

I've done that. Using an improper tool to try to remove a tight second stage cover. You stick both handle ends of pliers in opposing holes, then a screw driver on the top of the pliers and twist and try not to push the pliers down too far. I learn stuff the hard way.

There is no way the reg worked adequately before service with a major tear in it like that.

If it's a SP reg I'm going with it being punctured while someone was trying to remove face plate pin.
