SECTION 7 –
PLUMBING
7-8
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
specifically 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.
See winterizing instructions at the end of this
section to prepare the toilet for storage in freezing
conditions.
Further Information
See the toilet manufacturer’s operation
information in your InfoCase for complete
operating, care, and maintenance information.
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
appropriate waste water disposal site. This means
you can use the toilet, sinks and shower even in
areas where utility hookups are not available.
The black water holding tank contains the
sewage from the toilet and may include bathroom
lavatory on some models. The gray water holding
tank contains the waste water from the galley
sink and shower, and may include bathroom
lavatory.
See
Specifications
in Section 1–Introduction
for tank capacities for your model.
Dumping Holding Tanks
The waste drain (sewer) hose features a
convenient handle and valve nozzle for sanitary
handling and improved waste disposal.
1. Remove the dust cap from the drain outlet and
connect the sewage drain hose. Twist to lock
the hose end hooks onto the pegs on the drain
outlet. Be sure it is firmly attached.
NOTE: The dump valve drain outlet swivels
downward when necessary to avoid
bends in the drain hose which could trap
solids while dumping or to provide more
direct drainage while using on-site
sewer hook-ups.
2. Push the handle forward to open the hose end
valve, then extend the hose and place the
nozzle into the disposal opening.
NOTE: The hose end valve (handle) must be
opened before pulling the hose to the
disposal opening. If the valve is closed, a
vacuum will develop and prevent the
hose from expanding fully.
