sewage back-up into gray tank. Gray
water also rinses any black water solids
from the sewage drain hose.
5. Open the Gray Waste Tank Drain valve
(located beneath driver side rear
compartment). Press and Hold the Waste
Pump switch (located in the water service
center). Release the Waste Pump switch and
close the Gray Waste Tank Drain valve as
soon as the tank is empty.
NOTE: Sound of Waste Pump will change
significantly when tank is empty.
6. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV stores.
7. 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.
Using On-Site Sewer Hook-Ups
The sewer 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
sewer hose and drain in the normal manner.
NOTE: Always keep sewage drain outlet
capped while sewage connection is not in use.
