WASTE WATER SYSTEM
(HOLDING TANKS)
The drainage system is self-contained and
uses two separate holding tanks to contain the
waste water until it can be dumped at an appro-
priate waste water disposal site. This means you
can use the toilet, sinks and shower even in areas
where utility hookups are not available.
The main holding tank contains the sewage
from the toilet, and is commonly called the black
water tank. The second holding tank contains the
waste water from the galley sink, bathroom lava-
tory and shower, and is commonly called the grey
water tank.
The waste drain (sewer) hose has a handle and
valve as a sanitary convenience feature. The han-
dle makes the hose easier to carry when placing
into a dump site receptacle and when rinsing and
storing. The valve end reduces the chance of
dripping from the hose which could get onto
shoes or pants or inside the compartment.

DUMPING HOLDING TANKS

1. Attach the drain hose and place head of
sewer hose into disposal opening.
2. Unlock the hose handle and push it forward
to open the valve inside the hose head.
NOTE: Do not open the tank valves until the
hose valve is open. If you open the dump
valve before the hose valve, the hose will
fill with sewage and may clog in addition
to being difficult to move.

3. Open the sewage (black) tank valve with a
quick pull. OPEN ONE VALVE AT A
TIME. Move hose gently about to dislodge
any waste and to ensure complete drainage.
NOTE: Do not open the grey tank valve until the
black tank is drained and dump valve
closed to avoid sewage back-up into grey
tank. Grey water also rinses any black
water solids from the drain hose.
