WATER SYSTEMS
Winterizing with antifreeze:
Ten gallons of FLA approved RV antifreeze will be required to winterize the
motorhome.
1. Empty and flush the holding tanks.
2. Remove the water filter element from the galley spigot and reassemble
with diverter cap.
3. Remove the drain plug from the front of the water heater. At the back
of the water heater, turn the water heater bypass valve to Bypass.
4. Open all faucets. In the water service compartment, open the low point
drains and drain valve for the fresh water tank. Operate the water pump
to clear water pump of water.
5. Close all faucets, drain valves and low point drains.
6. Pour the antifreeze into the fresh water tank using the fresh water
gravity fill.
7. Turn on the water pump and operate each faucet (hot and cold valves)
individually until a small amount of antifreeze is present.
8. Close off the faucets.
9. Open the shower faucets and toilet valve to allow a small amount of
antifreeze to run into the holding tanks.
10. Use a soft cloth to wipe out the sinks and shower to protect
surfaces from antifreeze stains.
11. Open the exterior faucet using the same procedure as the
interior faucets.
12. If the motorhome is equipped with an icemaker in the
refrigerator, remove the 3/4” fitting and flush antifreeze through the
water line.
13. Disconnect the power supply line affecting water pump
operation.
To de-winterize, drain and fill the fresh tank with water. Connect the power
supply line for the water pump. Install drain plug to water heater and switch bypass
valve to Normal Flow. Operate all faucets, one at a time, until clear water is
present.
WARNING: Use only specifically designed non-toxic RV antifreeze for
potable water systems. Automotive antifreeze, if ingested, can cause
blindness, deafness or death.
CAUTION: Discard the first two trays of ice from the icemaker. They
may contain contaminant.
WARNING: It is recommended that a qualified RV service
technician familiar with motorhomes, such as an authorized dealer, do
this procedure.
