for tank capacities for your model.
Flushing your Black Water Holding
Tank
The black water holding tank is equipped with
an internal spray head that allows you to rinse the
inside of the tank with a shower of clean water
after dumping.
1. Dump your black water holding tank in the
usual manner at approved sewage disposal
station.
2. Leave black water dump valve open while
flushing tank.
3. Attach a garden hose from a city water
hydrant to the Flushing System 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 dump valves.
Using On-Site Sewer Hook-Ups
The drain hose may remain attached to the
dump outlet and be routed out the flip-down
hatch in the bottom of the compartment while the
motor home is parked and connected to an on-site
sewage hook-up.
The center outlet section may be swiveled
downward for better hose alignment and
drainage.
NOTE: Always keep service access passage
closed while utility connection is not in
use.
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.
Holding Tank Level Indicators
See Systems Monitor Panel in Section 4–
Appliances for further information on the
monitor panel and checking tank levels.
See Specifications in Section 1–Introduction

WATERLINE & TANK DRAIN
VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system.
To Drain Tanks and Waterlines:
The waterline and tank drain valves are
located in an exterior compartment. Turn the
valves as indicated on the label provided,
according to the type of valve installed.
Drain valve locations are listed in the Water
