Drainage System (P-Traps); Waste Water System - Winnebago Vista User Manual

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 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 (Model 35B is
equipped with four holding tanks - two black and
two gray) to contain the waste water until it can
be dumped at an appropriate waste water disposal
7-8
site. This means you can use the toilet(s), sinks,
and shower even in areas where utility hookups
are not available.
The black water holding tank(s) contains the
sewage from the toilet(s) 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.

Black and Gray Waste Tank Drain Valve positions may
be reversed, depending on floorplan and tank location
NOTE: The sewage drain outlet swivels
downward (on certain models) 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.
