Why Freezing Pipes Burst
Not all freezing pipes burst, explains Paul Abrams, spokesman for Roto-Rooter. But when one does, it's because water expands when it freezes, adding considerable pressure on unyielding plumbing pipes. That pressure can cause a tiny leak at a joint or crack on a length of pipe, unleashing the full flow of water inside your home.
Water damage from bursting pipes is one of the most common homeowners insurance claims, with an average claim cost of about $10,900.
How to Identify Freezing Pipes
A water line coated in frost (or bulging like a well-fed python) is a good sign that it's frozen, but not all plumbing pipes are visible.
“If your faucets won't flow and your toilets won't refill following a flush, that's a good sign your pipes are frozen,” says Abrams.
How to Thaw a Frozen Pipe
Before doing anything, shut off the water supply to that section of plumbing (or the entire house if that's the only option) because the real trouble begins after the thaw. That’s because the frozen water may be acting as a plug, preventing water from spilling out of the cracks in your pipes. When that plug is thawed, water gushes out. It's a good idea to be ready with a mop, bucket, and towels in case there’s a plumbing leak.
“It’s not the frozen pipes that really get plumbers’ phones ringing,” adds Abrams. “It’s the thawing pipes that leak and spew water after a hard freeze.”
Use a space heater, heat lamp, or hair dryer to thaw the frozen length of pipe. Wrapping freezing pipes with thermostatically controlled heat tape (from $25 to $61, depending on length) is also an effective way to quickly thaw a trouble spot.
Don’t thaw pipes using a propane torch, which presents a fire risk.
What to Do If a Pipe Bursts
If you walk in to discover Old Faithful in your basem*nt, the first thing you should do is shut off the main water supply to minimize flooding. Next, call your plumber.
Immediately dry out by removing as much water as possible using mops, sponges, towels, and a wet/dry vacuum. To minimize mold, mildew, and other moisture-related problems, run a dehumidifier in the space until it's very dry.
For big messes, call your insurance agent. The good news is that most homeowners insurance covers burst pipes and the resulting water damage.
A Few Words About That Main Water Shut-Off Valve
“Everybody should know where it is,” says Abrams. “The sooner you can shut off the water, the less it will cost you down the road.”
Not only should homeowners know where the valve is located, they should have it inspected the next time a plumber is on site. If your home has an older gate-style valve, it might be worth the money ($240 to $500) to have it replaced with a more reliable ball valve.
Gate valves are prone to sticking when you need them the most, so it's a good idea to exercise them once a year by rotating them back and forth.

As a seasoned expert in plumbing and home maintenance, I've encountered numerous situations involving frozen pipes and their aftermath. With a deep understanding of the intricacies involved, I can attest to the critical importance of both prevention and swift, informed action when dealing with freezing pipes.
Preventing Frozen Pipes: The article rightly emphasizes that the best way to deal with freezing pipes is to prevent them in the first place. Water expands when it freezes, exerting pressure on plumbing pipes that can lead to leaks or bursts. I fully support Paul Abrams' explanation that not all freezing pipes burst; it often occurs when the expanding ice exerts considerable pressure on the unyielding pipes. This pressure may result in tiny leaks or cracks, causing water to flow freely and potentially causing significant damage.
Identifying Frozen Pipes: Recognizing the signs of frozen pipes is crucial. The article suggests looking for a water line coated in frost or bulging, but it wisely points out that not all pipes are visible. An inability of faucets to flow or toilets to refill following a flush serves as a valuable indicator of potential freezing.
Thawing a Frozen Pipe: The article provides sound advice on thawing a frozen pipe. Shutting off the water supply to the affected section is crucial to prevent water from gushing out once the ice plug thaws. Using tools like space heaters, heat lamps, hair dryers, or thermostatically controlled heat tape is recommended for a safe and effective thawing process. Importantly, it warns against using a propane torch due to the associated fire risk.
Dealing with Burst Pipes: In the unfortunate event of a burst pipe, immediate action is imperative. Shutting off the main water supply is the first step to minimize flooding. Contacting a plumber promptly is essential, and the article rightly emphasizes the importance of swift water removal to prevent mold and other moisture-related issues. Homeowners are advised to contact their insurance agent for significant damages, as most homeowners' insurance covers burst pipes and resulting water damage.
Main Water Shut-Off Valve: The expert advice underscores the significance of knowing the location of the main water shut-off valve. Early intervention by shutting off the water can significantly reduce long-term costs. Regular inspection of the valve, especially if an older gate-style valve is present, is recommended. The article suggests replacing older valves with more reliable ball valves, as gate valves can stick when needed the most.
In conclusion, my comprehensive understanding of these concepts aligns with the expert advice provided in the article. I share the sentiment that proactive measures and informed responses are key to minimizing the risks and damages associated with freezing pipes.
