Hello, my name is Andrew Etchen. I am a master plumber and the owner of
Andrew Etchen Plumber's Service, Inc. located in Livonia, Michigan since 2001.
Freezing temperatures can cause significant damage to water piping and fixtures.
Over the years we find that there are two common situations that result in
freeze damage. First, is where a building or home with recently added
or installed plumbing in walls or ceilings. Completed remodeling projects or alterations
installed without adequate protection against freezing are disasters waiting to
happen. If this applies to you, you should worry, or at least be highly concerned
and aware that prolonged freezing temperatures could cause those new pipes to freeze
and burst, causing significant damage. The second situation is where a home
or building is now occupied by new owners or tenants. Not realizing that
certain plumbing plumbing pipes and equipment can be exposed to freezing temperatures
often get a quick and costly lesson.
Everybody is busy, and people are sometimes caught off guard when the freezing
temperatures arrive. Recently, we were called out to a school in Southfield,
Michigan where the backflow preventer for the lawn sprinklers had frozen and burst.
This device is typically installed outside and needs to be winterized
in the fall. Blowing out the lawn sprinklers had not been scheduled
yet, and then the temperature, unexpectedly dropped way below freezing for several
days, causing the device to freeze and burst. They were unaware of the situation
until warmer temperatures began to thaw the frozen pressure vacuum breaker and
water was spraying everywhere.

We replaced the destroyed device with a new Wilkins model # 720 (stock photo).
