After each use, drain the pipes by shutting off the water with the main T-valve in
front of the tank. Then open all faucets. Prop them open with a piece of wood. No
water, no freezing!
•
If you’re storing the water
trailer, make sure you drain
all
the water remaining inside.
Park the trailer on a slight
incline so that the water is tilt-
ed toward the drain plug. When
the water stops draining, don’t
assume it’s all gone. Open the
manhole cover and check.
Next, open all the faucets
and the main T-valve. That pre-
vents a vacuum in the pipes and
lets all the water drain.

Water expands as it
freezes. That means
the water pipes on
your trailer could
burst if you don’t
take care of ‘em.
Follow these tips…
•
Place the water
trailer in a shelter,
especially if the tem-
perature is below
0°F. A warm tent or
other shelter that has
a field range or other
heater in use is best.
At the very least,
keep the trailer cov-
ered with canvas.
•
Always keep the manhole and filler covers tightly
closed. That helps keep the cold air out.
man, that tent
heater’s gonna
feel
mighty
good
tonight!
c-can I
c-come,
t-t-too?
Keep manhole cover
tightly closed
Shut off water with T-valve…
…or pipes may burst
Put trailer on incline when draining water
Add
cold
to
water
and you get
ice.
That’s great if you
need a few ice cubes
for your tea, but it
can be
disastrous
for your water
trailer.
