5. Turn the water pump on for
approximately 30-60 seconds and allow
it to run so that all the water is cleared
out of the water pump and water tank.
6. Turn the pump off.
7. Close hot and cold low point drain
valves, fresh water tank line drain
valve, and winterization valve.
8. Leave open fresh water
tank drain valve and
fresh water tank low
point drain valve.
9. Open the water
heater exterior access
panel. Open the high
temperature/pressure
relief valve to vent
water heater. Remove
water heater drain plug to allow
water heater to drain. When water has
finished draining, replace water heater
drain plug and close pressure relief
valve.
10. Locate bypass valve at back of the
water heater and move valve to
BYPASS position.
11. Connect an air hose
with regulator to the
City/Fresh Water Fill
connection. Position
the City/Fresh Water
Control lever to the
“City Water” position.
Set regulator to 40
PSI and turn on air
compressor.
DO NOT
exceed 40 PSI
in the water lines and faucets.
12. When water stops flowing from low
point drain valves, open all faucets
- including outside faucet and shower,
one at a time, until air comes out. This
will clear water from supply lines.
DO
NOT
forget to drain the shower faucet.
13. Hold toilet mechanism open (flush
toilet) until the water has stopped
running.
14. Shut off the air compressor and
disconnect the air hose.
15. One gallon of FDA approved RV
antifreeze is needed 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. This will protect
the P-traps with some of the antifreeze
going into grey tank to protect the
drain valve. Open the toilet bowl valve.
Pour another 3 pints into the toilet,
letting the antifreeze run into the black
tank to protect the valve located there.
If applicable, pour the last pint of
antifreeze into the washer/dryer drain
after the toilet bowl valve has been
closed.
16. Use a soft cloth to wipe out the sinks
and shower (after the antifreeze is
poured in) to protect the surfaces from
stains.
17. Open hot and cold low point drain
valves, fresh water tank line drain
valve, fresh water tank drain valve, and
fresh water tank low point drain valve
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.
WARNING:
Clean up antifreeze spills immediately to
prevent permanent staining.
Using Non-Toxic Antifreeze
Approximately five to eight gallons of FDA
approved antifreeze will be required to winterize
the motorhome.
WARNING:
It is recommended that a qualified
RV service technician familiar with
motorhomes, such as an authorized
dealer, do this procedure.
WARNING:
Use only specially designed, non-toxic
FDA Approved RV antifreeze for potable
water system. NEVER use automobile
engine antifreeze. If ingested, antitfreeze
can cause serious injury or death.
