<strong>Gemini</strong> 105Mc Owner’s <strong>Manual</strong><br />
Fresh Water System<br />
The <strong>Gemini</strong> has (2) two 30 gallon fresh water polypropylene<br />
tanks located under each of the aft cabin<br />
bunks. There are (2) two 1 ½” fresh water fills on<br />
the aft coaming for each tank. Each fill also has a<br />
½” tank vent built into the cap. When filling the<br />
tanks, the fill line is located just under the vent<br />
line. Take care not to overfill the tanks. If the<br />
tanks are overfilled, they will leak through the inspection<br />
port on top of the tanks. If when filling<br />
the tanks you discover the water backing up in the<br />
fill line, it’s likely there’s water in the vent line.<br />
To clear the vent line, detach the vent tube from<br />
the tank (loosen hose clamp and work hose off<br />
barb), and blow air through the line to clear it.<br />
When using these water fills, push a hose all the<br />
way into the hole to avoid spraying water into the<br />
vent at the top of the fill. A 1’ section of garden<br />
hose with a stopcock on one end makes filling the<br />
tanks an easy job. Insert the flexible end into the<br />
fill and the connect the stopcock end to the water<br />
hose.<br />
Cold Water System: Coming from each tank is a<br />
draw hose which meet at the tank selector “Y”<br />
valve located in the port aft cabin. Continuing<br />
from the “Y” valve, the water travels back under<br />
the aft port bunk through to a strainer and then to<br />
the Flojet pump. The pressure pump is primarily<br />
used for showering and has a non-return valve inside<br />
the pump to maintain pressure in the system.<br />
From the pump, the water travels to (2) two “T”<br />
connectors. The first “T” connects to the cold water<br />
line for the head. The second “T” connects to<br />
the galley cold water line and the (6) six gallon<br />
water heater.<br />
The cold water line to the galley travels through a<br />
tiptoe foot pump located on the floor beneath the<br />
sink and then to the faucet. Caution: When using<br />
the foot pump, make sure that the cold water knob<br />
on the faucet is in the “open” position to avoid<br />
undue pressure in the line which could damage the<br />
pump and/or faucet.<br />
The water tanks are constructed of ABS plastic, and<br />
the hoses are designed as taste free. Theoretically<br />
these materials do not impart a taste into the water.<br />
Additives are available to help reduce the taste<br />
of plastic in the water. After water is stored for<br />
long periods, chlorine may be necessary to make<br />
the water useable. For occasional use, bottled water<br />
is good for drinking and the tank water will do<br />
for washing.<br />
Hot Water System: The (6) six gallon hot water<br />
heater is heated from the engine cooling water or<br />
from the 110 volt electric water heater. Hot water<br />
travels out of the heater to a “T” connector which<br />
Plumbing, Head, & Water Systems<br />
splits the line to both the head and galley. The pressure<br />
pump must be “on” to use hot water.<br />
There is a red handled valve in the front end of the<br />
engine compartment that is used to shut off the hot<br />
water going to the water heater tank. When the<br />
handle is pointing down, the engine is not heating<br />
the water. When the handle is horizontal, the water<br />
in the tank is being heated.<br />
When on shore power, a switch on the main 110V<br />
panel turns on a 110V electric element in the tank,<br />
which heats the water.<br />
Caution: Do not operate the hot water heater on<br />
110v without water in the heater tank—otherwise<br />
you will likely burn out the heating element. To fill<br />
the heater tank, turn on a hot water faucet until<br />
water comes out, indicating the tank is full. Just as<br />
important is to make sure you do not run out of water<br />
in your 30 gallon tanks resulting in an empty hot<br />
water tank.<br />
Pressure Water Pump<br />
The water pressure pump is situated under the port<br />
aft bunk. <strong>Gemini</strong> comes with a Flojet pressure pump<br />
for fresh water. The main reason for pressure water<br />
is to use the shower and hot water. The pressure<br />
pump has a non-return valve that keeps the pressure<br />
in the line. The pump has a pressure switch that<br />
switches the pump on when the pressure drops to 15<br />
psi and off when the pressure reaches 25 psi. If the<br />
pump cycles on and off every few seconds, first<br />
check for a leak in the system. It also could be that<br />
for some reason the non-return valve in the pump is<br />
not holding pressure. If so, disassemble the pump<br />
and clean the debris out of the valves.<br />
The pressure pump should be turned off when not<br />
needed because even in a perfect system it will<br />
come on and off periodically wasting battery power.<br />
Galley Toe Tip Pump<br />
There is a Whale foot pump in the floor beside the<br />
galley. This pump does not have a diaphragm. Instead,<br />
the pump is like a bicycle type pump that can<br />
take pressure. This pump is in the line direct from<br />
the pressure pump to the cold faucet in the galley.<br />
This pump can only be used when the pressure pump<br />
is not in use. The purpose of this pump is to conserve<br />
battery power and water and to be able to get water<br />
from the tanks if the pressure pump does not work.<br />
Turn 90º and press to lock in the down position.<br />
Reverse the procedure to enable the pump.<br />
