Tools/Supplies Required
Never use AUTOMOTIVE type antifreezes when
winterizing the System. This may result in serious
injury or death.
Only plumbing antifreeze, consisting primarily of
propylene glycol with no ethanol or other alcohols,
rated for -58
o
F (-50
o
C), may be used to winterize
the System. The use of less-expensive ‘non-
propylene glycol based’ plumbing or RV antifreezes
may damage the System’s internal components
voiding all warranties . This may also result in
serious injury or death.
Plumbing antifreeze containing propylene glycol
will provide protection of the System against
freezing to -40
o F (-40 o C) as long as the proportion
of antifreeze to water is correct. This procedure
only protects the System from freezing and does
not protect the rest of the household water
distribution system.
Propylene glycol based antifreeze is available at
most hardware stores.
WARNING!
All valves

Prefilter can be stored in the System for the winter in
Step 7.
