SECTION 7 –
PLUMBING
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 provided in your InfoCase for
complete operating, care, and maintenance
information.
DRAINAGE SYSTEM (P-TRAPS)
Ensure there is an adequate amount of water in
the drainage system p-traps to avoid sewer odor
from entering your motorhome.
If you should experience a sewer odor, pour
approximately 1 cup of water down each sink and
shower drain in the motorhome.
Washer/Dryer
–If Equipped
In addition to pouring water down sink and
shower drains, also run a wash cycle to ensure
there is an adequate amount of water in the
washer p-trap.
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
7-8
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
1. Remove sewage drain hose from water
service center.
2. Remove dust cap from sewage drain outlet
and connect sewage drain hose. Be sure it is
firmly attached.
