Refilled with (non-distilled) bottled water and went on to go thru the whole 4-day event, and then drove all the way back home, with no issues. Car and water pump are still fine today....

Not to put too fine a point on it, but you stated that with " 'just' (sic. only)distilled water you can drive the car safely". That was the basis of my disagreement.

Your friend has added bottled water to the system, but it wasn't completely dry from your description, nor would I expect it to be from just a failed cap. So, while diluted, I suspect there was still sufficient coolant in the car to lube the pump, etc.
