As discussed as to at what temperature do pipes freeze we know that water freezes at 32 degrees fahrenheit and therefore pipes that are installed outdoors have a much bigger chance of freezing as soon as it passes the 32 degrees fahrenheit mark.
Water pipes freezing in attic.
Water inside the pipes can still freeze.
You can also wrap pipes in heat tape or heat cables with a thermostat control.
Surprisingly both hot and cold pipes can be at risk.
Insulate pipes located in the attic and crawl space using pipe insulation even if the climate where you live does not often have hard freeze conditions.
Otherwise a cold water line run a long distance through a hot attic can take several.
Because water always flows downward freezing attic pipes that rupture are especially damaging to the living spaces below.
Because the reality is if you end up with a burst pipe in your attic due to freezing the amount of water damage is going to be extensive.
Within minutes water will travel throughout your attic down your wall cavities and through your ceiling.
But exposed plumbing in areas such as crawl spaces attics and garages may be at risk.
It can potentially flood every floor of your home within a few minutes.
There are number of steps you can can take when learning how to keep pipes from freezing in the first place.
Because most attics are unconditioned a hard freeze that plunges attic temperatures into the mid 20s for any length of time can cause a burst pipe.
