and allows water remaining in the hose to drain
down. This is a normal function of the shower
valve assembly and is not a leak or defect.
If items are placed into the shower tub before
shower valve vacuum release is complete, they
may become wet.
EXTERIOR SHOWER/WASH
STATION
–If Equipped
The exterior wash station feature allows you
to do things such as rinse off sand or salt after a
swim, rinse off muddy boots, or bathe your pet
outside the coach. Some models may have a
water pump switch located near the shower
faucet for convenience.
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.
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.
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.
