[C320-list] Shower Sump

[Bob Borelli]

Mark,  on my boat there is one seacock for the sump pump drain.   The shower water goes from floor sump thru hose to PAR pump screwed into 1/4" plywood panel glued to hull thru hose to a its sea valve.  Located behind the head vanity in the space behind aft stateroom drawers & closet, sea valve by vanity obvd sea valve & head suction sea valve.  Total 3 valves thru hull.

Suggestion is tee into vanity sink drain hose above sea valve with check valve above the tee.

Fiddler’s Green was built before shower sump pumps were included and I would like to add one.  Currently, the shower drains directly into the bilge and the main bilge pump pumps it overboard.  My bilge has had oil in it before and, due to the hull liner, it is difficult to remove all residual oil from the boat, so I don’t like pumping even the slightest amount overboard.

I’ve measured and have room for the smaller Rule 800 GPH unit, and I would like to know where the factory-installed units discharge.  Does the hose run all the way back to the stern like the main bilge pump?  Any other installation issues?

Thanks!
