a things i just found:

|What is the one thing they didn't tell you about being a submariner?
|Your shit and anything that goes into a toilet will end up in a "Sanitary Tank". The shower/sink water goes into a separate tank. Over time these shit tanks that are 100's of gallons will need to be emptied. This is done one of two ways.
|You pump it overboard with a heinz pump. It is not reliable, slow, and loud.
|You pressurize the tank above sea pressure which can be over 350 psi and blow it overboard. It is faster and more reliable.
