NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste Tank
Drain Valve until the black tank is
drained and Black Waste Tank Drain
Valve closed to avoid 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. 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.
6. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV supply
centers.
7. Rinse sewage drain hose thoroughly with
water before stowing.
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 and be routed out the
bottom of the compartment while the motorhome
is parked and connected to an on-site sewage
hook-up.
• 1st - Pull Black
Waste Tank
Drain Valve to
drain Black
Water
(sewage)
Tank, then
close.
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.
NOTE: Always keep sewage drain outlet capped
while sewage connection is not in use.
