WINTERIZING PROCEDURES
Certain areas of your water system require
additional attention and disconnecting or
blowing out these lines may be required. Be sure
all water is drained from the system.
You can winterize the water and plumbing
system of your coach using one of the following
two methods – 1) Blow out waterlines using
compressed air or – 2) Fill waterlines with RV
water system antifreeze.
Further Information
Refer to the Water Heater manufacturer’s user
guide provided in your InfoCase for complete
winterizing procedures.
Method 1 – Blow Out Procedure
(Drain and purge waterlines using
compressed air)
1.
Level the Motorhome.
If the coach is not
level, there may be “low points” in waterlines
that can trap water in the lines and prevent it
from draining properly.
2.
Drain Fresh Water Tank and Waterlines.
Open all waterline drain valves and drain
fresh water tank. (See “Water System Drain
Valve Locations” chart at the end of this
section for locations of drain valves on your
model).
3.
Drain Exterior Shower/Wash Station.
Open exterior shower knobs and lay shower
head on ground as shown to drain any water
left in the shower line.
Also, place the tip of your finger into the city
water inlet and gently press the backflow
valve “button” in the center of the inlet to
drain any water trapped in the inlet line.
4.
If Equipped with Cold Water Filter:
Remove the filter canister from the Cold
Water Filtration System under the galley sink
and discard the filter cartridge.
After emptying the canister, remount it onto
the filter assembly and continue the Blow-Out
Procedure.
Drain Water Heater (with Tank)
