WINTERIZING PROCEDURE

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.
Method 1 – Blow Out Procedure
(Drain and purge waterlines using
compressedair)
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 end of this section
for locations of drain valves on your model).
3. Drain Exterior Shower/Wash Station (if
equipped).
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.
