black water (sewage) tank, then close.

drain gray water (sink/shower), then close.
*Model 59K
NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste
Tank Drain valve until the black tank is
drained and dump 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 stores.
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.
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.
