PLUMBING
Fill Lines
5. Turn the Water Pump switch ON.
6. Open each hot and cold water faucet handle/
knob in the coach - one at a time each in turn
until antifreeze solution just begins to flow
from the faucet, then close.
Do not forget the exterior shower/wash station
knobs.
7. Press the toilet flush pedal and hold until
antifreeze begins flowing into the toilet.
Leave small amount of antifreeze that remains
in the bowl.
When Done Adding RV Antifreeze
8. Turn Water Pump switch OFF.
9. Turn Winterization Valve 2 to the “Normal”
position.
This will stop the flow from the Antifreeze
Siphon Tube and revert the tank line flow to
the water pump.
10. Replace the protective cap onto the end of the
Antifreeze Siphon Tube to keep out insects
and debris when not in use.
Drain Water Heater
11. Turn OFF the Water Heater power switch
before draining the water heater tank to avoid
damage to the heating element.
12. Drain the water heater by removing the plug
from the base of the water heater tank,
accessible from the outside of the coach
(requires socket and ratchet).
13. Open the Pressure-Temperature Relief valve
at the top right portion of the tank to prevent
air locking in the tank while draining.
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.
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.
