You
can prevent frozen pipes.
Frozen pipes aren't just an inconvenience. An
average of a quarter-million families have
their homes ruined and their lives disrupted
each winter…all because of water pipes that
freeze and burst.
A 1/8 inch crack in a pipe
can spill up to 250 gallons of water a day,
wrecking floors, furniture and keepsakes. Both
plastic (PVC) and copper pipes may burst.
By taking a few precautions,
you can save yourself money and aggravation
frozen pipes cause.
Here are a few simple steps
to protect your home:
Insulate
pipes in your home's crawl spaces and attic.
These exposed pipes are most susceptible to
freezing. Remember: The more insulation you
use, the better protected your pipes will be.
Heat
tape or thermostatically-
controlled heat cables can be used to wrap
pipes. Be sure to use products approved by an
independent testing organization, such as
Underwriters Laboratories Inc., and only for
the use intended (exterior or interior).
Closely follow all manufacturers' installation
and operation instructions.
Seal
leaks that allow cold air inside, near where
pipes are located. Look for air leaks around
electrical wiring, dryer vents and pipes. Use
caulk or insulation to keep the cold out and
the heat in. With severe cold, a tiny opening
can let in enough cold air to cause a pipe to
freeze.
Disconnect
garden hoses and, if practical, use an indoor
valve to shut off and drain water from pipes
leading to outside faucets. This reduces the
chance of freezing in the short span of pipe
just inside the house.
A
trickle of hot and cold water might
be all it takes to keep your pipes from
freezing. Let warm water drip overnight,
preferably from a faucet on an outside wall.
Open
cabinet doors to allow heat to get to
uninsulated pipes under sinks and appliances
near exterior walls.
Set
the thermostat in your house no lower than 55
degrees (12 degrees Celsius).
Ask
a friend or neighbor to check your house daily
to make sure it's warm enough to prevent
freezing, or…
Shut
off and drain the water system. Be
aware that if you have a fire protection
sprinkler system in your house, it will be
deactivated when you shut off the water.
Don't
take chances If you turn on your
faucets and nothing comes out, leave the
faucets turned on and call a plumber. If you
detect that your water pipes have frozen and
burst, turn off the water at the main shut-off
valve in the house; leave the water faucets
turned on. (Make sure everyone in your family
knows where the water shut-off valve is and
how to open and close it.)
Never
try to thaw a pipe with a torch or other open
flame. Water damage is preferable to burning
down your house. You may be able to thaw a
frozen pipe with the warm air from a hair
dryer. Start by warming the pipe as close to
the faucet as possible, working toward the
coldest section of pipe.
