Waste Water System - Winnebago Minni Winni Owner's Manual

If you should experience a sewer odor, pour
approximately 1 cup of water down each sink and
shower drain in the coach.

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 sewage drain hose from rear bumper
storage.
2. Remove dust cap from sewage drain outlet
and connect sewer hose. Be sure it is firmly
attached.
NOTE: The sewage drain outlet on your coach
may swivel downward (depending on
model) when necessary to avoid bends in
the sewage 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 sewage drain hose into
disposal opening.
1st - Pull Black Waste Tank Drain
valve to drain black water (sewage)
tank - then close.
2nd - Pull Gray Waste
Tank Drain valve to
drain gray water (sink/
shower) tank - then
close.
NOTE: Black and Gray tank valve positions may
be reversed depending on floorplan and
tank 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 is 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 and stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
