SECTION 10
PLUMBING SYSTEMS
TOILET
The toilet in your motor home is very similar
to the household type, except that it is designed to
use only a small amount of water per flush. It
uses a high velocity jet of water, producing a
swirl effect, to efficiently cleanse the bowl.
1. Press the pedal down completely and hold
until bowl is clean. Release pedal slowly. A
small amount of water will remain in the
bowl.
2. To add more water to the bowl than the nor-
mal 2" automatic refill, press the pedal part-
way down and hold until desired amount has
been added. Release pedal slowly.
Please refer to the manufacturer's information
supplied with the toilet for further operating and
maintenance instructions.
Important "Don'ts"
• Don't use facial tissue or regular toilet tissue
in the RV toilet. These will not disintegrate
sufficiently and will often cling to the sides of
the holding tank. Toilet tissue made specifi-
cally for use in RV toilets and holding tanks
is available at most RV supply centers.
• Don't dispose of sanitary napkins or other
non-dissolving items in the toilet.
• Don't put automotive antifreeze or caustic
chemicals, such as laundry bleach or heavy
detergents into the toilet or holding tank.
These products may damage plastic or rubber
parts in the system.
Cleaning the Toilet
The toilet should be cleaned regularly for
maximum sanitation and operating efficiency. If
an odor is apparent from the toilet:
10-6
1. Clean the toilet bowl with a mild bathroom
cleaner. Do not allow cleaners to set in the
bowl for long periods of time to avoid dam-
aging the seals. Do not use caustic or abra-
sive cleaners because it may damage the
plastic surfaces.
2. Dump and rinse holding tank.
3. Add odor control chemical in amount speci-
fied after cleaning and every few days during
use.
4. Remove the water line from the base of the
toilet and clean the screen.
5. If the flush valve becomes stiff after
extended use, it may be lubricated with a sil-
icone spray.Turn the water pump off and
operate flush pedal to drain water from the
toilet bowl. Spray silicone lubricant onto
flush valve inside bowl and operate flush
pedal a few times to ensure free operation.
See winterizing procedures at the end of this
section to prepare the toilet for storage in freez-
ing conditions.
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
gray 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.
