above ground swimming pool pump?
Answers:
It's rare, but has happened to me on a couple installations, that the impellor wasn't threaded all the way down on the shaft.
It shouldn't matter what method you use for going from lo to hi or vice versa. You can acutally, just go either way instantly and not stop as you are doing.
My hunch on this, is that he's giving you the same pump, that someone is not doing anymore than tightening the impellor down, until the shaft spins, and not holding the shaft and continuing to spin it, to compress the spring in the shaft seal. That'll do it everytime. Even on lo speed, with it not snugged in, it'll travel a good 1/4 inch and come to one helluva abrupt halt, splitting the impellor shaft.
Get the guy to bench test it at his shop or threaten to stick it you know where. I doubt his techies are up to the job.
