Brand new Scubapro MK25 sputtering

Who else finds the term "broken in" scary?
Ok, it could be just me.

Deleted my long post about, seats and pistons and whatnots 'setting in' first and 2nd stages etc, that's for another topic.

The word 'broken' does not sit well when talking about regulators with my OCD mind.
What broke?

Haha yeah I realize it is unsettling after I posted. I am unfamiliar with the inner workings of regulators so please disregard, I was just borrowing lingo from mechanics.

But my uneducated guess is that it was a combination of the water temperature, which resulted in a certain rigidity of the diaphragm along with my inhale rate which happened to hit the resonance frequency of the diaphragm just right

I agree, that sounds like an uneducated guess!

The more likely probability at this point is that there was nothing wrong to begin with.

I really doubt it had anything to do with water temperature. When 2nd stage diaphragms are installed, there is usually a friction ring which keeps the diaphragm from twisting a bit as the 2nd stage cover is installed, and helps to even out the pressure on the lip of the diaphragm by the cover. Occasionally this doesn’t work perfectly and you get some fluttering, although usually this is dampened in the water. I’ve done things like re-orient the diaphragm in the reg body a little, and use some back-and-forth movement when tightening the cover to help alleviate any rotational stress on the diaphragm. It really is a minor issue, although when you spend a lot of money on a regulator you expect it to work perfectly right from the start.

I’m glad it seems to be working now for you.
