Pipes are most likely to burst when exposed to below-freezing conditions for six hours or more, which can happen throughout winter and early spring. Burst pipes could lead to a disaster, bringing severe water damage to your home.
This finding was supported by a survey of 71 plumbers practic- ing in southern states, in which the consensus was that burst- pipe problems began to appear when temperatures fell into the teens. However, freezing incidents can occur when the tem- perature remains above 20 degrees F.
The optimal water pressure for most home water pipes is 40 to 45 psi. At the most, your water pressure should never exceed 60 psi. If it does, your water pipes are vulnerable to bursting.
So, the question is: just how cold does it have to be for pipes to burst? Your pipes are at risk of freezing any time temperatures drop below 32°F. However, it's much more common for pipes to freeze when temperatures dip below 20°F.
When water freezes, it expands, which can create pressure in your pipes and cause them to burst. So your pipes can potentially burst when temperatures drop below 32 degrees Fahrenheit. However, the time it will take for them to burst depends on just how cold it is and for how long.
Pipes are most likely to burst when exposed to below-freezing conditions for six hours or more, which can happen throughout winter and early spring. Burst pipes could lead to a disaster, bringing severe water damage to your home.

Pipes can freeze in as little as six to eight hours, meaning they can freeze overnight. If the outside temperature is below 32 degrees F and your pipes are unprotected, your chances for a frozen pipe increase.
The rule of the thumb is that it takes roughly 6-hours for water in your pipe to freeze after left in an unheated area. Meaning if you lose power at your home and the weather is reaching below freezing point, you have approximately 6-hours until the pipes will begin to freeze.
What temperature do pipes freeze in a house? We all know that freezing begins at 32° F or 0° C, but at what point do pipes freeze within our own homes? Temperatures only need to drop to about 20° F for a few hours to put exposed pipes at risk.
Water supply pipes in unheated interior areas like basements and crawl spaces, attics, garages, or kitchen cabinets.
