[C320-list] fresh water leak

[JPMESA at aol.com]

We have a fresh water leak somewhere, and so far haven't been able to  locate 
it. It pools in the furthest aft bilge section and under  the sink/cabinet 
area. (We removed  the teak/holly sole).  None  of the lines or connections 
(including the hot water heater and pressure  pump) under the sink & cabinet 
drawers are leaking.  We removed the  cabinet/drawers to clearly see all the lines 
and connections.  The forward  tank doesn’t seem to be leaking. Are there any 
connections not easily viewable  to the aft tank?  Do the water lines ever 
chafe through or crack in funny  areas and need replacing??  Any ideas???
