SEA COCK and plumbing diagrams:  We prepared diagrams and annotated photos showing the location of each through hull fitting.  A PDF copy of this manual can be viewed by clicking [here]. BILGE PUMPS.  The rules require "two permanently installed manual bilge pumps, one operable above, the other below deck. Each pump shall be operable with all cockpit seats, hatches and companionways shut and shall have  permanently installed discharge pipe(s) of sufficient capacity to accommodate simultaneously both pumps".   I installed a second Whale Gusher pump under the port side settee and ran the hose to a new overboard fitting next to the existing fitting.  We also converted the engine winterizing valve to a screened intake in the bilge.
