Plumber with Pipe

How Cold Does It Have to Be for Pipes to Freeze?

While there’s plenty of plumbing maintenance for California homeowners to worry about during the winter, you might assume that frozen pipes would not be a major concern for homeowners in this state. However, this is not necessarily the case.

Information varies on how cold it has to be for pipes to freeze, but the freezing temperature of water is 32 degrees. So, theoretically, your pipes could freeze at any temperature lower than that. But for your pipes to literally freeze overnight, the temperature would probably have to drop to at least 20 degrees. The good part of this is that in California, even in the coldest months we rarely experience temperatures in the 20s and 30s for prolonged periods of time.

On the other hand, it’s key to remember that water expands as it freezes. This means that your pipes do not have to be frozen solid for them to become damaged. Think of it this way: if you leave a glass of water out overnight, and it freezes even part way by morning, that means the same thing can happen in your pipes. So during the chilliest months of the year, if your exterior pipes have any amount of frozen water in them, they can still burst from pressure if the water gets cold enough.

How to Stop Your Pipes from Freezing

Chances are it will be your outdoor pipes, such as the ones attached to sprinklers and pools, or the spigots around your house, that will be most vulnerable to freezing. Pipes in locations such as your garage, attic, or basement (though there aren’t many basements in Southern California) can also be at risk, and even some pipes under your kitchen and bathroom sinks can freeze if it gets too cold.

Fortunately, you can purchase products such as pipe sleeves to prevent your exterior pipes from freezing. You should also make sure your outside lines are turned off during the winter, and add insulation at points on your property where your pipes may be vulnerable.
