Richard J. Hanak:
When water is pumped into a water tower, a pump provides the force to raise the water from a lower potential to a higher potential. In that last sentence the word ‘raise’ means ‘moved farther from the center of the earth.’

Not in the vernacular.
"Raise" would mean to follow the line of the plumb bob, but if you were to continue the line of the plumb bob, it might miss the center of the Earth by tens of kilometers, depending upon latitude. So, raising something is to move at an angle to the line to the center of the Earth.

Also, what does your model predict about the tidally induced shape of an object that is not rotating (or is tidally locked with its companion)?

Is that two different questions? If an object is tidally locked to its companion, it will be rotating, once per revolution.
That was the point that I made earlier, and I think Richard went back and fixed that up.
