Winterizing and Preparing for Extreme Cold Weather
As cold weather
approaches there are some things that homeowners and associations should
consider to be proactive to avoid frozen pipes and potential water damage.
PREVENTING FROZEN PIPES
Every winter, homeowners suffer from the destruction,
frustration, and the financial burden caused by freezing and bursting water
pipes. Freezing can occur in any water pipe exposed to temperatures of 32ºF or
below. As freezing water expands, it generates enough pressure to burst pipes
and fixtures. When frozen pipes thaw, flooding can occur and cause extensive
damage. Pipes in garages, attics, crawl spaces, and unheated rooms are
particularly susceptible to freezing. Pipes in exterior walls may also freeze
when temperatures fall below freezing during severely cold weather.
During the winter, taking a few simple precautions, you can
avoid the frustration, destruction, and expenses caused by frozen pipes. Access
Management Group recommends you use this guide to help prevent frozen pipes and
protect your investment.
DID YOU KNOW?
An eighth-inch (three millimeter) crack in a pipe can leak
up to 250 gallons (946 liters) of water per day. Both plastic (PVC) and copper
pipes can burst.
BEFORE COLD WEATHER HITS
Know Where Your Shut-Off Valve Is – All responsible household members should know where the
home’s shut-off valve is located prior to needing it for an emergency. Every
home should be equipped with a shut-off valve. Generally a stop and drain valve
is located on the service line on your side of the water meter, near the house.
If you live in a condo or townhome, you may have a shut-off at your water
heater or where your water line enters your unit. Unfortunately, not all units
have a main shut-off. If you have one, locate it so you can shut off the water
if a break occurs.
Insulate Pipes and Faucets – If you have pipes in unheated areas, such as the garage or a crawl
space under the house, insulate them with items such as pipe wrap, foam
jackets, or heat tape. Insulating products are available at local hardware
stores or building supply retailers. Follow all manufacturers’ installation and
operation instructions. If you have questions, call a professional for help.
Simply insulating the pipes will help during a short cold spell but a long term
cold spell will ultimately cause the unheated pipe to freeze even if insulated.
If you are concerned about this potential, we recommend installing heat tape
under the insulation against the water pipe. Install insulated covers on your
exterior hose bibs. Again during extreme cold, these could still freeze due to
a lack of a heat source. Shut off hose bibs from the inside, if you have that
capability and if a cut off is available. This is the surest way to avoid these
from freezing. Remember to drain the line outside after turning off the valve.
Seal Off Air Leaks – With cold winter winds, a tiny opening can let in enough
cold air to freeze a pipe. Look for leaks around dryer vents, electrical
wiring, and pipes. Use caulk or insulation to keep the cold air out. Don’t
cover or block air vents from your water heater or furnace; proper ventilation
is important for those items.
WINTERIZING CHECKLIST
Shut Off and Drain Outdoor Irrigation
System
- Set the automatic irrigation controller to the “Off”
setting.
- Turn off water to the irrigation system at the stop and drain valve. Many
homes have separate stop and drain valves for the outdoor water supply. Make
sure the different valves are labeled so they are easy to identify.
- Drain all water out of any irrigation components that might freeze. Some
systems may drain automatically. The system may not drain completely based upon
how it is installed but draining as much water as possible is a positive
action.
- Disconnect garden hoses from hose bibs.
Shut Off and Drain Indoor Plumbing to
unheated buildings such as pool houses.
- Shut off water using the stop and drain valve. Use caution to
make sure this valve has been completely turned off. If this valve isn't closed
correctly, the water will continue to feed the building and/or flow out the
drain valve if the main valve is not properly closed.
- Drain all water out of the pipes by opening every faucet until
the water stops running. After the water has stopped, turn off the faucets. If
water does not stop, go check the stop and drain valve to make sure it’s shut
off all the way.
- Flush toilets.
- Pour biodegradable anti-freeze into all toilet bowls, toilet
tanks, and sinks to displace water in the drain pipes. Carefully follow
manufacturers’ instructions and always store in a child and pet proof location. RV antifreeze is the best product to use since
regular automobile antifreeze can damage toilet wax rings and other components
of the plumbing system.
- Open your hot water drain valve, usually located at the low point of your
hot water pipes. If you choose to drain your hot water tank, turn off the gas
or electric supply to the heater. If you do not turn off the water heater, it
will continue to try and heat the water and cause your heater to malfunction.
This will result in the potential for fire and total replacement of the water
heater.
- Not all buildings are designed to be totally drained and there
is a possibility that there could still be water left in the piping system that
could freeze. If you turn the water back on after winterization, check all
plumbing to ensure you do not have a broken pipe. If a pipe is broken, turn the
water back off and call a plumber or the AMG emergency line immediately.
ALTERNATIVE FREEZE PREVENTION
- Instead of draining your water system,
you may heat the building to avoid freezing pipes. However, leaving the
thermostat at 45 to 55 degrees does NOT always ensure that the pipes will not
freeze. Winter storms may cause power outages, which will cause some heating
systems to shut off, resulting in frozen pipes.If you are going to be away from your
home and it is the time of year that cold weather may be a concern, make sure you
leave your unit with the heat on.
- If you are in a Condominum or Townhome, your
unit not being heated may cause a water line break and now you have also
flooded your neighbors and cause thousands of dollars of damage to yourself,
others and the common association areas.
- Letting your water drip slightly is
also a method that can be used since moving water freezes slower than water
simply sitting in a water line.
- Open cabinet doors to allow heat to
flow easily around water pipes.
IF YOUR PIPES
FREEZE
If
you turn on the faucets and nothing comes out, call a plumber or the Access Management
Group Emergency Line immediately. The
AMG Emergency Line is our main line number at (770) 777-6890 and follow the
prompts. We can send personnel to your home to help evaluate the
situation.
Open all faucets in the house.
When water freezes, it expands by 1/5th its original volume.
By relieving pressure, due to the expanding water, you may avoid additional
pipe damage.

AFTER THE THAW
Once your pipes have thawed, it is
important that you carefully inspect your home for any signs of a leak. The
freezing of the pipes could have caused a pinhole leak, hairline break, or
large crack.
If the water lines are in an attic
space it would be wise to ensure the piping is covered with insulation and is
best if they are within the heated envelope of the unit. Ensure that if pipes
in these areas are repaired and the insulation is disturbed that the
insulation be placed back into its original configuration and not left
exposed to freeze another day.
