Hi Bob,
I'm afraid that's not a realistic proposition. There is a fair amount
of iron in this well and those passages are probably packed with hard
scale. Considering the amount of time and effort to remove the switch,
it's cheaper to buy even the more expensive commercial model, than to
take it off and replace it again when the first fix fails. If I lived in
a 3rd world country and the nearest replacement was months away, I would
definitely do this. However, as it hasn't failed completely yet, right
now I just need some info on the capability of the standard switch
versus the commercial version.

Thanks,

Jim

PS Yes, I even have a genuine points file, but I suspect after one pass
over those industrial grade contacts which carry 230 volts, they'd be
useless. Filing points on breaker sets only worked when there were no
replacements handy, it usually led to a faster demise of said breaker
points.

The SquareD pressure switch for my well pump is becoming flaky, either
sticking on or not coming back on. I checked Grainger for a replacement
and it appears that the current switch is a commercial job SquareD 9013
GSG2, 30-50 cut off. This switch sells for 56 bucks at Graingers, while
a standard model (FSG2) with the same spec is only about 18 dollars.
This pump and well is now used primarily for home use, although in the
past it was used for some irrigation. Do I really need the expensive
commercial model or will I be OK with the standard model.

You could try removing the old switch and cleaning the passages that allow
the pressure into the switch. You can also clean the contacts by filing them
lightly with a fine, thin file (some fingernail files would work) or
sandpaper.
