Oh, thanks for the clarification! Yes, the springs... Good to know they won't fatigue.
DIY S600 "seat saver" ?

Push in purge button and turn it to the left, it takes pressure off seat. A push back turn to the right and it will re engage.
Merry Xmas, you're welcome

Thanks for that. Had no idea. Now I wish all my 2nds had this feature.

Which will be of no consequence to anyone anywhere ever

Understanding that moving parts of any apparatus (including springs) get fatigued, wouldn't the spring get a lot less fatigued by having it depressed (typically only once when setting the "seat saver") than the seat itself that is constantly being pushed on?
Well, one of my 45+ years old SP 109 had a spring failure 3 years ago (that is, after 42 years of intense usage)...
Fatigue takes a huge number of alternated compressions-relaxations for building up.
But for intensely used equipment (say, in diving centers), probably this can happen in 10-15 years of daily usage.

I guess that proves my point. If your spring failed after 45 or so years, depressing the spring for seat saving purposes would be justified to save the seat.

Indeed, I have heard of metal fatigue, but what I meant is that the conclusion to my question earlier seems to be that the springs in our regs are not really harmed by storing them with the purge depressed...
