SECTION 7 –
PLUMBING
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.
NOTE: Always keep sewage drain outlet capped
while sewage connection is not in use.

WASTE WATER SYSTEM -
WASTE PUMP (MODEL 27Q)
(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 the
bathroom lavatory on some models. The gray
water holding tank contains the waste water from
the galley sink, shower, and may include
bathroom lavatory.
See “Specifications” in
Section 1–
Introduction
for tank capacities for your model.
Waste Pump
The 12-volt Waste Pump disposes gray
holding tank waste through a small diameter
sewer hose, which is then drained through the
main sewage drain outlet.
NOTE: If Waste Pump stalls, check breaker in
the load center. If problem persists,
remove end cap and manually turn pump
shaft (located on the end of the Waste
Pump) with a screwdriver.
Further Information
For further information and operating
cautions, see the Waste Pump operating
instructions included in your InfoCase.
