7. While the air is on, hold the spray nozzle (located right next to the
toilet) open until the water has quit running. Hold the toilet flush
pedal or handle down until the water has stopped running.
8. Unhook the air hose and close the city water connection.
9. Use 1 gallon of RV antifreeze to protect various water drain lines in
the motorhome. Pour 1 pint into both the kitchen and bath shower
drains. Pour 2 pints into the bath sink drain, with some of the
antifreeze going into grey tank to protect the drain valve. While
holding down the flush pedal, pour another 3½ pints into the toilet,
letting the antifreeze run into the black tank to protect the valve
located there. Pour the last pint of antifreeze into the toilet after you
releasing the flush pedal. Use a soft cloth to wipe out the sinks and
shower (after the antifreeze is poured in) to protect the surfaces
from stains.
10. Leave the low-point drains open until the motorhome is used again.
WARNING: When draining the low water drain lines and the
water heater be sure the water is not hot. Hot water from the
lines can burn or injure skin.
If filling the water lines with antifreeze is preferred, use 5 gallons of FDA
RV winterizing antifreeze.
1. Remove water filter cartridge and replace filter with diverter cap
(see WATER FILTER). Diverter cap comes with motor home and
will be stored inside. With diverter cap installed it will create a bypass
in water lines.
2. Drain the fresh water tank and lines by opening the tank drain valve and
the low point drain valves located in the outside water control service
compartment of the motorhome.
3. Let all the water drain. Turn the pump on and allow it to run so that all
the water is cleared out of the pump and lines. Turn the pump off.
4. Remove water heater drain plug and open pressure release valve
located in the outside water heater access compartment.
5. After the water is drained, move water heater bypass valve to BYPASS
setting located next to water heater. Replace the water heater drain plug
and close the pressure release valve.
6. Close the fresh water tank drain valve and the low point drain valves.
7. Close the water tank shut-off valve and open the winterization connection
valve.
8. Install a hose to the winterize connection and drop the other end of hose
into the anti-freeze container.
9. Turn ON the system water pump and operate each faucet individually until a
small amount of antifreeze is present.
10. Close the faucets.
