15. Pour about one cup of RV antifreeze down
each drain for the galley sink, lavatory sink,
and shower/tub. This fills the drain trap pipes
to prevent holding tank odors from entering
the coach during storage.
NOTE: It is not necessary to add antifreeze to
the toilet since the flush valve will be
closed.
Do not add automotive antifreeze or
caustic chemicals such as bleach or
laundry detergents into the toilet bowl or
holding tanks. Although these products
may have a deodorizing effect, they may
damage plastic and rubber parts in the
system.
16. Empty the water pump strainer filter bowl to
avoid water freezing and cracking the filter
bowl. See "Water Pump" previously in this
section.
