A/C raw water discharge

[starsailor]

Recently had a problem with my 2007 Tiara 4300 Sovran A/C raw water discharge.  Due to a blockage in the discharge line from the manifold/collector raw water was pushed back through the collector up through the Day Hatch drain.  I want to relocate the A/C overboard discharge.  I have been told that the later 4300/4500 drains are located in the swim platform rub rail.  Two 3/4 inch ball valves  just outboard of the A/C units.  Anyone with  2010 or later have this setup, if so could you confirm how this is setup or pictures would be even better.

Tiara has been no help, not their installed setup for this model year


Thanks in advance
