pipe at buttom of waterpump

I've got a 1997 c280 with a 104.941 6 cyl. engine.
I recently got a leak which appeared to be coming from a pipe at the bottom of the water pump which was neither connected to anything or plugged.
Is there a stopcock that goes in there or a hose which goes there?
Thanks to anyone who can help.

According to the WIS drawing, there should be a hose in there called the 'leak water pipe' (4a).

It is not clear, but it looks to me (from the added guide-line) that the lower end goes into the engine block.

Strange? Is this water pump designed to leak?
