I wonder how he knew when to turn the compressor off. Pressure tanks can have variable water to air ratios. Where would THAT have been written down (and handed down) for the engineer to know? And yes, whatever that ratio is will push the last water out without the compressor but it needs to be on to maintain that initial setup.
