<strong>Gemini</strong> 105Mc Owner’s <strong>Manual</strong><br />
Shower Sump Pump<br />
The shower in the <strong>Gemini</strong> is mounted to the wall<br />
with a door that can be opened to close off a separate<br />
area for showering and leave a dry area for<br />
clothes and towels.<br />
The shower water collects in the sump which is capable<br />
of holding (6) six gallons. To empty the sump<br />
press the switch on the wall below the sink. The<br />
pump is a Gulper 220 under the floor of the navigation<br />
station. This pump is self-priming and drains the<br />
grey water directly overboard. The pump is powerful<br />
enough to serve as a auxiliary bilge pump. Simply<br />
disconnect the shower hose and connect a second<br />
hose.<br />
Plumbing, Head, & Water Systems<br />
pointing right pumps overboard and pointing left<br />
pumps into the holding tank.) Below are all the possible<br />
valve configurations for the toilet:<br />
Overboard<br />
Toilet<br />
The toilet is a Raritan PHII, (Practical Sailor recommended).<br />
This is a marine toilet with a lever handle<br />
that gives a mechanical advantage making pumping<br />
the toilet easier. An electric motor can be added to<br />
pump the toilet; however this is not an option from<br />
the factory.<br />
The pump has a dial, which is turned counterclockwise<br />
to flush the toilet and clockwise to close the<br />
incoming water to pump the toilet dry. Caution:<br />
When sailing and pitching in rough water, always<br />
close this dial on the top of the toilet pump to stop<br />
water flooding back into the toilet and flooding the<br />
boat.<br />
A ¾” inlet seacock and 1½” outlet seacock are behind<br />
and below the toilet. With the handle to the<br />
left the ¾” inlet seacock is allowing water in from<br />
the sea. With it coming straight out it is closed and<br />
with the handle pointing to the right it is allowing<br />
fresh water to be pumped into the toilet from the<br />
sink. Pumping fresh water into the toilet is to prevent<br />
odor from the bacteria in seawater when the<br />
toilet is left for a long period of time.<br />
To use the fresh water flush, set the 3-way seacock<br />
located in a cabinet just outside the head, opposite<br />
the navigation station, to “Fresh Water Flush.” This<br />
seacock controls the drain from the sink and has<br />
three positions: Off, Overboard, and “Fresh Water<br />
Flush.” In order to pump fresh water from the sink<br />
into the toilet: fill the sink with water, turn the sink<br />
seacock to “Fresh Water Flush,” turn the 3/4” toilet<br />
seacock to the right, and pump the toilet flush handle<br />
until all the water from the sink has been sent<br />
through the system. You can add a small amount of<br />
bleach to the water to further clean the lines out.<br />
The Y valve behind the toilet directs the toilet water<br />
either overboard or into the holding tank. (The<br />
long end of the handle points to the hose in use; i.e.<br />

Holding Tank<br />
Into Holding Tank<br />
Gravity Drain Holding Tank<br />
The holding tank is located directly behind the toilet<br />
and is on the same level as the sail locker base. The<br />
holding tank is 18 gallons with a 1 ½" inlet at the top<br />
against the outside of the hull. The 1 ½" outlet is at<br />
the bottom against the outside hull. The vent is on<br />
the same side with a ½" hose going across the tank<br />
to a through hull fitting under the sink. The holding<br />
tank can be inspected visually through the Plexiglas<br />
bulkhead in the sail locker. It may be necessary to<br />
shine a flashlight behind the toilet from the other<br />
side of the tank to illuminate the fluid at the same<br />
time.<br />
In the top of the tank is a 4" inspection cover. The<br />
tank can be inspected by unscrewing the top shelf in<br />
the sail locker. The tank can be removed through the<br />
sail locker by cutting the marine sealant tabbing that<br />
holds the vertical Plexiglas wall below the shelf in<br />
the sail locker.<br />
