SECTION 7 –
PLUMBING
1. Dump your black waste holding tank in the
usual manner at an 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 on the right sidewall. (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 garden 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 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.
Holding Tank Level Indicators

WASTE WATER SYSTEM
(MODEL 70KL)
(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 bathroom lavatory.
The gray water holding tank contains the waste
water from the galley sink and shower.
See “Specifications” in
Section 1 -
Introduction
for tank capacities for your model.
CAUTION
Keep drain valve closed to minimize the
presence of sewer gases.
Sewer gases can be present when RV is
connected to campground sewage
hookup. Can lead to illness or personal
injury.
Black Waste Tank Flush Inlet
(Located on right sidewall)
WARNING
Service inlet access must be closed when
utility connections are not in use.
