16. Hold toilet mechanism open until the
water has stopped running.
17. Shut off the air compressor and
disconnect the air hose.
18. 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.
19. Use a soft cloth to wipe out the sinks
and shower (after the antifreeze is
poured in) to protect the surfaces from
stains.
20. Leave all 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.
NOTE
Clean up antifreeze spills immediately to
prevent permanent staining.
Using Non-Toxic Antifreeze
Approximately ve 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 specifically designed, non-toxic,
FDA Approved RV antifreeze for potable
water systems. NEVER use automobile
engine antifreeze. If ingested, antifreeze
can cause serious injury or death.
NOTE
Freeze damage is not covered under
warranty.
