SECTION 7 –
PLUMBING
1st - Pull Black
Waste Tank Drain
valve to drain
black water
(sewage) 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.

Sewage Drain
Outlet/Dust Cap
2nd - Pull Gray
Waste Tank Drain
valve to drain
gray water (sink/
shower) tank -
then close.
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.
Using On-Site Sewer Hook-Ups
The sewage drain hose may remain attached to
the dump outlet and be routed out the bottom of
the compartment while the motor home is parked
and connected to an on-site sewage hook-up.
NOTE: Always keep service access passage
closed while utility connection is 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.
Holding Tank Level Indicators
See "Systems Monitor Panel" in Section 4 -
Appliances for further information on the
monitor panel and checking tank levels.
See "Specifications" in Section 1 -
Introduction for tank capacities for your model.
WASTE WATER SYSTEM -
WASTE PUMP
(Holding Tanks)
(For coaches equipped with Waste
Pump feature only - Model 26Q)
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.
