CAUTION
Hot water can escape from tank causing
injury. Operate relief valve or remove
drain plug only when the tank water is
cold.
13. Open the Pressure-Temperature Relief valve
at the top right portion of the tank to prevent
air locking in the tank while draining.
Pressure Temperature Relief Valve
(Lift handle only when water heater is cold)
14. Reinstall the water heater drain plug and close
the Pressure-Temperature Relief valve when
drained.
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.

Shower Drain Pump

Press and Hold the Waste Pump switch for
approximately 5-10 seconds to get antifreeze
