See the toilet manufacturer's operation
information in your InfoCase for complete
operating, care, and maintenance information.

WASTE WATER SYSTEM

(Holding Tanks)
The drainage system is self-contained and
uses two separate holding tanks to contain the
waste water until it can be dumped at an
appropriate waste water disposal site. This means
you can use the toilet, sinks and shower even in
areas where utility hookups are not available.
The black water holding tank contains the
sewage from the toilet and may include bathroom
lavatory on some models. The gray water holding
tank contains the waste water from the galley
sink and shower, and may include bathroom
lavatory.
See Specifications in Section 1–Introduction
for tank capacities for your model.
Dumping Holding Tanks
1. Remove drain hose from water service center.
2. Remove dust cap from drain and connect
sewer hose. Be sure it is firmly attached.
NOTE:The dump valve drain outlet swivels
downward when necessary to avoid
bends in the drain hose which could trap
solids while dumping or to provide more
direct drainage while using on-site
sewer hook-ups.
3. Place the outlet end of sewer hose into
disposal opening.

Holding Tank Dump Valves (Typical)
NOTE: Black and Gray tank valve positions may
be reversed depending on floorplan and
tank location.
4. Open the black water valve (black handle)
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 water valve as soon as
tank is empty.
NOTE:DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the gray tank 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 drain
hose.
5. Open the gray water valve (gray handle). Be
sure there are no sags in the hose to ensure
complete drainage. Close gray water 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 R.V. stores.
7. Rinse sewer hose thoroughly with water and
stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
