Water flows downhill whenever it can. It will do so
even if it has to rise at first, provided its final level
is lower than its initial level and there is no air in
the connecting pipework. A system in which water
rises and then falls as it flows of its own accord
under gravity is called a siphon.

Manual and electric marine toilets flushed with sea
or river water require connections through the hull
below water level. If the toilet is installed below the
boat's waterline, the possibility of flooding the hull
through an open seacock must be prevented, not
only for the discharge pipe, but also for the inlet
pipe.
If no precautions are taken, a toilet below the
waterline is at risk of flooding at all times when the
discharge or inlet seacock is open (A).
A loop of pipe above water level (B) may prevent
flooding, but there remains a risk that a siphon will
be created by pumping the toilet, or when the boat
heels, or by wave action.
