Fill Drainage System P-Traps
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.
Dump and Clean Holding Tanks
16. Completely drain the waste water holding
tanks at an approved waste disposal site.
Drain the sewage (black) tank first so the
following waste water can rinse any waste
solids from the dump outlet and sewage drain
hose.
17. Close waste tank drain valves and refit the
dust cap onto the sewage drain outlet.
This will inhibit rust formation on valve shafts
and prevent entry and contamination by
airborne debris, insects, and rodents.
Your drainage and fresh water systems are
now winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
To Winterize the Waste Pump
• Ensure that black and gray holding tanks are
completely empty.
• Pour 2 gallons of RV antifreeze down the
toilet.
• Open Black Waste Tank Drain valve.
• Open Sewage Drain Hose valve.
• Press and Hold the Waste Pump switch for
approximately 5-10 seconds to get antifreeze
into the pump.
• Close Black Waste Tank Drain and Sewage
Drain Hose valves.
