SECTION 7 -
PLUMBING
NOTE: Model 35B is equipped with two sets of
Black and Gray Waste Tank Drain
Valves - one set is in the driver side
compartment ahead of rear axle, and
the other set is in the driver side
compartment behind the rear axle.
Therefore, Steps 4 and 5 must be
performed at each location.
4. Open the Black Waste Tank Drain Valve with
a quick pull and make sure there are no sags in
the hose. Move the hose gently about to
dislodge any waste and ensure complete
drainage. Close 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 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(s). 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.

Tank
The black water holding tank is equipped with
an internal spray head that allows you to rinse the

after dumping.

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

hydrant to the Black Waste Tank Flush Inlet
fitting in the water service center. (This inlet is
clearly marked separate from the City Water
inlet).
