Using Non-Toxic Antifreeze
If you choose to fill the water lines with antifreeze, you will need 5 gallons of FDA RV non toxic antifreeze.
1. Drain the fresh water tank by opening the fresh water tank drain valve.
2. Drain the low point drain valves.
3. Let all the water drain.
4. Turn the water pump on and allow it to run so all the water is cleared out of the water pump and fresh
water tank. Turn the water pump off.
5. Remove water heater drain plug and open pressure relief valve.
6. After the water is drained, move water heater bypass valves to bypass position. Replace the water heater
drain plug and close the pressure relief valve.
7. Close the low point drain valves.
8. Close the fresh water tank shut off valve and open the winterization valve.
9. Insert the winterization hose into the antifreeze container.
10. Turn on the water pump and sequentially open each faucet individually until a small amount of
antifreeze is present. Close the faucets. Do not forget the exterior faucet (if equipped).
11. Open the shower faucets and flush toilet to allow a small amount of antifreeze to run into the holding
tanks.
12. Use a soft cloth to wipe out the sinks and shower to protect surface from antifreeze stains.
13. Turn water pump off.
14. Disconnect the hose and store.
WARNING:
Use only non-toxic RV antifreeze that is
specifically made for potable water systems.
Automotive antifreeze, if ingested, can
cause blindness, deafness, or death. It is
recommended that this procedure be done
by a qualified RV service technician familiar
with motorhomes, such as the authorized
selling dealer.
De-Winterization:
For de-winterization, open the fresh water tank
shut off valve and close the winterization valve.
Close low point drains. Fill the fresh water tank
with water. Turn on the water pump and operate all
faucets, one at a time, until clear water is present. If
applicable, install a new water filter. Fill the water
heater with water.
