4. Open the Gray Waste Tank Drain valve. Be
sure there are no sags in the hose to ensure
complete drainage. Close Gray Waste Tank
Drain valve as soon as tank is empty.
5. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV stores.
6. Rinse sewage drain hose thoroughly with
water and stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
Flushing Your Black Waste Holding

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.

usual manner at an approved sewage disposal
station.
2. Leave Black Waste Tank Drain valve open
while flushing tank.

water to run for about three minutes.

and close Black Waste Tank Drain valve.
Using On-Site Sewer Hook-Ups
The sewage drain hose may remain attached to
the dump outlet and be routed out the bottom of
the compartment while the motorhome is parked
and connected to an on-site sewage hook-up.
WARNING
Service inlet access must be closed when
utility connections are 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.
