Gray Water System
If installed, the gray water system is used in areas where
dumping the fresh water waste products overboard is
prohibited. Gray water originates from onboard sinks and
showers. With this system all the gray water is pumped
into the waste holding tank (65 gal. capacity) via the
shower sump pump system verses directly overboard. The
holding tank periodically needs be to be pumped out by
a marina pump out station through the "waste" fi tting on
the starboard deck. Use the waste water portion of the
monitoring panel at the ship's main control panel to check
waste water levels.
Head (Toilet) System
The onboard head system features a two toilet system
taking advantage of minimal water usage. Both feature
vitreous china bowls, minimal maintenance, easy cleaning
and a wall switch keyboard.
The toilets are powered by 12 volt DC electricity and are
each controlled by 30 amp breakers located at the ship's
main salon control panel.
Under normal conditions, the head system operates from
the onboard freshwater tank. If dockside water is being
used the toilets still draw water from the freshwater tank.
A Few Notations About The Head System:
• Only human waste and toilet paper should be put in
the toilet. Never fl ush foreign materials such as paper
towels, pre-moistened wipes, condoms, feminine
hygiene products, dental fl oss or household garbage
down the toilet.
• Always disconnect the dockside water system if boat
is left unattended to avoid property damage due to
leakage.
• Refi ll the toilet as soon as possible after emptying the
bowl to prevent objectionable odors.
• Use only RV-Marine toilet tissues that disintegrate
rapidly. Do not use household type tissues.
• If repairs are needed, use only a trained and qualifi ed
marine technician or electrician.
