Drain Traps & Auto Vents
Sinks, shower and clothes washer drains
incorporate a water trap (P-Trap) and auto vents
to prevent waste water holding tank odor from
entering the motorhome.
Drain Traps:
P-Traps are usually within 54" of a vent tee
and must contain water to block odors. During
storage water can evaporate and allow odor into
motorhome. If odor is detected, run water into
sinks, shower and clothes washer to fi ll P-Traps.
Auto Vents:
The auto vent is designed to assist in the
smooth fl ow of water in the drain without
creating a vacuum. If stuck in the open position
the auto vent can allow grey odors to enter the
motorhome. Some auto vents can double as
"clean outs" in the event the line needs to be
snaked out.

COLD WEATHER CONDITIONS

Extended use in below freezing (32° F/0° C)
weather will require operation of the Aqua-Hot
system to protect interior water lines, fi xtures,
water storage tanks and pumps. Exposed
drains may freeze quickly. If in doubt about
what temperature the motorhome will tolerate,
winterize with potable antifreeze.

Cold Weather Storage

If the motorhome is stored where freezing
temperatures may occur, drain the domestic
fresh water loop. Begin draining the fresh water
tank by opening the low point drain for the fresh
tank and allowing the water to drain.
NOTE:
Icemakers, water filters, water purifiers
and the Aqua-Hot all use domestic
water and should be drained and stored
in accordance with the manufacturer's
recommendation for winterization.

WINTERIZATION

Water, plumbing and sewer systems require
winterization when the motorhome is placed
in storage. The recommended method of
winterizing the motorhome is using air pressure
to remove liquids that may freeze and cause
damage to the various systems and appliances.
The lines can then be left empty or fi lled with an
FDA approved RV antifreeze. When plumbing
070152b
lines are drained, antifreeze is not necessary,
and the decision to use antifreeze is left to the
motorhome operator.
NOTE:
Use only FDA approved RV antifreeze
to winterize the water systems in the
motorhome. Appliances must also be
winterized. Refer to their respective
OEM manual for proper winterization
instructions.
