How to deal with frozen pipes like a pro

One of the biggest issues with cold weather is it can freeze things, like the water in your pipes. When this happens, it can create a domino effect of cascading troubles, with each being more costly than the last.

Fortunately, our DIY expert, Beth Allen, founder of HIP Chicks (Home Improvement Project Chicks), can help you out if your pipes freeze this winter. Even better, she has tips to keep your pipes from icing up at all.

Which pipes are most vulnerable to freezing?

As soon as the air temperature drops to 32 degrees (or lower), water will freeze. Allen said that while the inside of your home should never drop below 32 degrees, unless you lose power or fuel, that does not mean your pipes are protected. Pipes in the crawl space are at risk of freezing, as are the pipes in the basement of an old or uninsulated home. Also, some pipes, such as the kitchen pipes, may run up an exterior wall, which makes them vulnerable to freezing as well. Additionally, any plumbing that runs through the attic or a garage is at greater risk of freezing. Lastly, Allen warned not to forget about outdoor hoses, swimming pool supply lines, and water sprinkler lines.

What problems do frozen pipes cause?

The most obvious problem with frozen pipes is they burst and create a leak. If this happens where the pipes are visible, at least you can see there is a leak, know precisely where it is and have access to fix it. A bigger problem is a pipe bursting inside of a wall. The leak may go undetected until you have major damage. This can include rotted wood, ruined walls and even a cracked foundation. It will also be hard to pinpoint and access a leak you cannot see.

The best defense against frozen pipes

Because frozen pipes can potentially cause so much costly damage, Allen said the best defense is to prevent them from freezing in the first place. Here are some ways you can do that:

What should you do if your pipes freeze?

If your pipes freeze, you have to learn how to safely thaw them because heating your pipes up too much can do more harm than good. And it can be dangerous. Allen said the best way to thaw frozen pipes is with a hair dryer. She added that it also helps to keep the faucets open so the water can begin moving again as it thaws, which will help melt more ice.

Allen cautioned you should never use an open flame, such as a blowtorch, or intense direct heat to thaw a frozen pipe. If you change the frozen water inside the pipe to steam, you might have an even bigger problem on your hands.

In a final word of advice, Allen said, “If there was any damage done to the pipe, you will find that out as soon as it is thawed because that’s when it will spring a leak. This is why it is important to know where your main water shut-off is and be certain that it works.”
