11. 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.
Dump and Clean Holding Tanks

holding tanks at an approved waste disposal
site. Drain the sewage tank first so the
following waste water can rinse any waste
solids from the sewage drain outlet and sewer
hose.

the sewage drain outlet.
This will inhibit rust formation on valve shafts
and prevent entry and contamination by
airborne debris, insects, and rodents.
