The hole appears to be right over one of the ballast water tanks, so the pumping was most likely removing ballast water (and the copious quantities from the deck flooding that would have gone down the hole also) ...
Only trouble with that answer is that the fins run on nitrogen gas..

New picture
Think of it like this -- the only way a three-engine burn makes sense is by bringing three engines to full thrust for just a few seconds, at a very low altitude (like less than a km) to brake from terminal velocity to zero. If it was possible to do a hoverslam and save fuel by doing a late, low-altitude single-engine burn at up to full thrust, they could have done that -- and I imagine that would use less fuel than starting up three engines.

N2 cold gas thrusters are used for nudges and maneuvering outside the atmosphere . GridFins use open hydraulic system which dumps into Merlin engine fuel cycle.

Thank you for the nomination of most negative, but I must decline the honor, as on the field of SX negativity, there is no way I can hold a candle to either Ed Kyle or Jim in that regard - they both beat me cold.

Since when is being evenhanded or skeptical counted as being negative.
