[C320-list] Head Vented Loops

[Scott Thompson]

My sense is that "medicine" cabinet is one of the areas where things are 
very different between older and newer boats. A recent thread mentioned 
sliding doors to the cabinet, but on my boat there are no sliding doors 
and I have the two vented loops. And dimensions of the head compartment 
changed significantly at one time (perhaps more than once.) Can't really 
use the cabinet for anything that shouldn't get wet as a consequence of 
the vented loops, since there can be a lot of dampness if one of the 
duckbill valves leaks even a little bit.

BTW, the second vented loop is not just for the shower drain, but also 
for the reefer drain on "newer" boats such as my 1999. You choose one or 
the other with a Y valve under the head sink.  We never use the shower, 
but drain the reefer often.

My older boat does not have the shower sump and pump.  My shower drain dumps right into the bilge (I have no plans to use my shower, especially with this poor setup).
