Winterization
Valve 1
• Open each hot and cold water faucet handle in
the coach one at a time until antifreeze
solution just begins to flow from the faucet;
then close.
When Done Adding RV Antifreeze:
• Turn water pump switch off.
• Turn the Winterization Valve 2 to Normal.
This will stop the flow from the suction tube
and revert the tank line flow to the pump.
• Replace the protective cap onto the end of the
suction tube to keep out insects and debris
when not in use.
Dump and Clean Holding Tanks:
• Completely drain the sewage and waste water
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 dump outlet and sewer hose.
• Flush the sewage tank using the Black Waste
Tank Flush Inlet.
• Close dump valves and refit the dust cap onto
the drain outlet.
Final Steps for "Blow-out" or
"Water System Antifreeze"
Procedure
1. Close all drain valves and faucets to avoid
contamination by dirt or insects. Reinstall
water heater drain plug and close P-T relief
valve.
2. Pour about one cup of non-toxic RV antifreeze
into the kitchen sink drain, bathroom sink
drain and shower drain. This prevents any
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.
