It is a glitch related more to the pumps than to other things.

Pumps have a problem (or not) - the outlet drops a little more than the Inlet took. And there's other problem - when draining huge amount (like the ocean itself) of water, the Inlet Pump takes water but the water level does not get lower. This is actually used a lot to build obsidian generators. So I'll explain to you what happened:

The inlet pump that was taking water from the ocean took some water and sent to the Outlet pump but did not lower the ocean level (because of the glitch i've already told you above), and therefore the Outlet Pump received infinite water and just dropped them infinitely, until it got submerged or stopped receiving signal.
