SECTION 7 –
PLUMBING
•
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.
Further Information
See the toilet manufacturer’s operation
information in your InfoCase for complete
operating, care and maintenance information.
See winterizing instructions at the end of this
section to prepare the toilet for storage in freezing
conditions.
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 coach.
If you should experience a sewer odor, pour
approximately 1 cup of water down each sink and
shower drain in the coach.
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
1. Remove sewage drain hose from rear bumper
storage.
2. Remove dust cap from sewage drain outlet
and connect sewer hose. Be sure it is firmly
attached.
NOTE: The sewage drain outlet on your coach
may swivel downward (depending on
model) when necessary to avoid bends in
the sewage drain hose, which could trap
solids while dumping or to provide more
direct drainage while using on-site
sewer hook-ups.
3. Place the outlet end of sewage drain hose into
disposal opening.
