I don't. A new ink goes in something clean that I want to use with the ink. Or maybe I'll just feel like testing whatever I'm using. The only time I suspect nib issues is when I get feathering. I use a 15x loupe to look for subtle ink properties and that's when I may notice the nib crushing or cutting the paper. I usually have a mix of pressure on my sample sheet and haven't noticed it affecting water resistance.

I've only run into one ink that confused me. River City Pen Company Triangle Pen Show Blue (later renamed Urban Ripple) was impervious to a spray of water that's wiped up. Water soaking into the paper over a few minutes erased the writing completely.
My current testing is a spray bottle squirt, wipe after 30 sec and see if it's legible. Then I soak the paper under the tap and check again for legibility.
@Unattributed
I've done durability tests, for lack of a better term. Based of methodology of an entomologist's lab notes methods and testing. My conclusion was that if an ink survives water, it does ok with other solvents.

@DadFather
Looks nice. Check the tine alignment and see if something needs a gentle nudge. Beyond that, I would leave it to pros.
@Unattributed
Like I said, he mentioned at least one paper. Listen to the video and there may be more.

Pretty sure sbrebrown mentions a paper but I didn't listen carefully enough to go find it.

I've had the tube in the section that the converter slides onto break. You could also try a cartridge or another converter.
@Paularhion
Is there ink behind the piston of the converter? If so, replace or, maybe, try greasing the piston.
