If the drain system does get clogged:
Use a hand-operated probe to loosen stubborn
accumulations. Seriously clogged P-traps may
require disassembly. Be careful not to over-
tighten when reassembling.
Do not use harsh household drain cleaners.
Do not use motorized drain augers.
Sometimes the holding tank valve will get
clogged. In this case, a hand-operated auger
may be necessary. Be ready to close the valve
quickly once the clog is cleared. If the seal gets
damaged, it is easily replaced.
WATER SYSTEM WINTERIZING
Read this section completely before performing
winterization.
If the motor home is to be stored unheated in
temperatures below freezing, the fresh water and
waste systems should be winterized. A detailed
storage and winterization procedure is outlined in the
26
"PREPARING THE MOTOR HOME FOR LONG TERM
STORAGE" section.
CAUTION: DRAINING THE WATER SYSTEM
ALONE WILL NOT PROVIDE ADEQUATE COLD
WEATHER PROTECTION. IF THE MOTOR HOME
IS TO BE UNHEATED DURING FREEZING
TEMPERATURES, CONSULT YOUR DEALER FOR
THE BEST WINTERIZING PROCEDURE FOR
YOUR CLIMATE. YOUR DEALER CAN WINTER-
IZE YOUR MOTOR HOME FOR YOU OR CAN
SUPPLY YOU WITH ONE OF THE SPECIAL ANTI-
FREEZES WHICH ARE SAFE AND APPROVED
FOR USE IN RV WATER SYSTEMS. FOLLOW THE
INSTRUCTIONS FURNISHED WITH THE
ANTIFREEZE.
WARNING: DO NOT USE AUTOMOTIVE OR
WINDSHIELD WASHER ANTIFREEZE IN THE
MOTOR HOME WATER SYSTEM. THESE COULD
BE HARMFUL IF SWALLOWED.
If the motor home is to be stored during freezing
temperatures, see "PREPARING THE MOTOR HOME
FOR LONG TERM STORAGE" section of this manual.
