Flushing Your Black Waste Holding
Tank
The black waste 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 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 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 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 and be routed out the flip-
down hatch in the bottom of the compartment
while the motorhome 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.
When using a sewer hook-up, keep the Black
and Gray Waste Tank Drain 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 sewage drain
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 sewage drain 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
See

WATERLINE AND TANK DRAIN
VALVES
The waterline and tank drain valves are used
to drain water from the water tank and the water
supply lines when preparing the motorhome for
storage or when sanitizing the water system.
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.
