Update: reality merely has too few instructions. The *right* details for each situation are too numerous to document. Senior maintenance guy came this morning and fixed plumbing issue in 5 minutes where assistant who tried yesterday struggled for 2 hours and still messed it up.

Trick was, a replacement valve had to be inserted into pipe in a half-open position so it slides in smoothly. Junior guy tried to jam it in full-open and damaged it. Sort of detail you’d either guess by insight, figure out trial-and-error, or see done right in apprentice mode.

I submit there is too much of this sort of detail to document in training manuals or books/videos. Too detailed to document. Kinda like too cheap to meter.

incidentally, one of my little desk 'toys' is a shower valve that I replaced many years ago and just sort of stuck around. it shuttles back and forth along its axis such that when you flush a toilet the pressure drop doesn't scald you. also, great for fidgeting
