1. Dump your black water holding tank in the
usual manner at approved sewage disposal
station.
2. Leave Black Waste Tank Drain valve open
while flushing tank.
3. Attach a garden hose from a city water
hydrant to the Black Waste Tank Flush Inlet
fitting in the water service center. (This inlet is
clearly marked separate from the City Water
inlet).
4. Turn the water on to begin flushing. Allow
water to run for about three minutes.
5. Disconnect hose from flushing system and
close Black Waste Tank Drain valve.
Using On-Site Sewer Hook-Ups
The sewage drain hose may remain attached to
the sewage drain outlet and be routed out the
bottom of the compartment while the motorhome
is parked and connected to an on-site sewage
hook-up.
When using a sewer hook-up, keep the dump
valves closed until a tank becomes full or when
preparing to leave the site. This keeps the solids
in suspension, allowing them to be carried out
with the liquids when the dump valve is opened.
If the valve is left open, the liquids will drain off,
leaving solids in the tank. Should this
accidentally happen, disconnect the hose, fill the
tank about half full with water, and drive a few
miles to dislodge the solids. A few starts and
stops will aid in the process. Then reconnect the
hose and drain in the normal manner.
NOTE: Always keep sewage drain outlet capped
while sewage connection is not in use.

WASTE WATER SYSTEM
(WASTE PUMP)
(Holding Tanks)
-Model 35F only
The drainage system is self-contained and
uses three 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 toilets, sinks, and shower even in
areas where utility hookups are not available.
The two black water holding tanks contain the
sewage from the toilets. The gray water holding
tank typically contains the waste water from the
galley sink, shower, and bathroom lavatories.
See “Specifications” in
Section 1–
Introduction
for tank capacities for your model.
CAUTION
Do not use the tank flush valve unless the
fullway termination valve is in the open
position. May result in an unsanitary
condition leading to illness or personal
injury.
