NOTE: Sound of Waste Pump will change
significantly when tank is empty.
7. Open the Rear Black Waste Tank Drain Valve
(located in the water service center). Move the
hose gently about to dislodge any waste and
ensure complete drainage. Close Rear Black
Waste Tank Drain Valve as soon as tank is
empty.
NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste Tank
Drain Valve until the black tanks are
drained and dump valves closed to avoid
sewage back-up into gray tank. Gray
water also rinses any black water solids
from the sewage drain hose.
8. Open the Gray Waste Tank Drain Valve
(located in the water service center). 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.
9. Add an odor control chemical to the sewage
holding tanks through both toilets. These
chemicals are available at most RV stores.
10. 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 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 valves are
