Frozen Pipes in Columbia, MO: Emergency Prevention Guide

---

Key Takeaways:

• Vulnerable Pipes to Watch: Pipes in unheated areas, on exterior walls, under sinks, and outdoor spigots are most at risk of freezing.
• Prevention is Key: Insulate pipes, seal air leaks, disconnect outdoor hoses, and let faucets drip during extreme cold to avoid frozen pipes.
• Handle Frozen Pipes Safely: Open faucets, apply gentle heat (like a hairdryer), and check for leaks after thawing. Call a plumber if the pipe bursts or remains frozen.

There’s a special kind of quiet that comes with a mid-Missouri cold snap. It’s the silence right before you turn on the faucet, hoping to hear the familiar rush of water, and instead… nothing. Just a hollow sound from the pipes and a sinking feeling in your stomach. A frozen pipe is one of the most stressful and potentially destructive problems a homeowner can face during our harsh winters.

When water freezes, it expands with incredible force—enough to split a copper or plastic pipe wide open. A small crack can release hundreds of gallons of water once it thaws, causing devastating damage to your floors, walls, and belongings.

The good news is that you don’t have to cross your fingers and hope for the best. With a little preparation, you can protect your home and keep the water flowing all winter long. This guide is your emergency plan for preventing a frozen pipe disaster before it ever starts.

Why Your Pipes Are at Risk (And Which Ones to Watch)

Pipes don’t freeze uniformly throughout your house. The most vulnerable ones are those exposed to the biting cold, with little or no insulation to protect them. Think of them as the soldiers on the front lines of your home’s battle against winter.

The pipes most likely to freeze are:

• Pipes in unheated areas: This includes your attic, crawlspace, basement, and garage. These spaces often lack the warmth from your home’s heating system.
• Pipes on exterior walls: Even with insulation in the wall, pipes located on the “outside” of that insulation can get dangerously cold.
• Outdoor hose bibs (spigots): These are directly exposed to the elements and can freeze solid if not properly winterized.
• Pipes under kitchen and bathroom sinks: Especially when those sinks are on an outside wall, the cabinet doors can block the flow of warm air from the rest of the room.

When the forecast for Columbia calls for temperatures to dip below 20°F, these areas need your immediate attention.

Your Pre-Winter Prevention Checklist

An ounce of prevention is worth a truckload of cure, especially when it comes to plumbing. Taking these steps before the first deep freeze can save you a massive headache and expense.

1. Disconnect and Drain Outdoor Hoses

This is the easiest and most important step you can take. Leaving a hose connected to your spigot traps water inside the faucet. When that water freezes, it expands back into the pipe inside your wall, causing it to burst.

What to do:

• Disconnect all garden hoses from the outdoor faucets.
• Drain them completely before storing them for the winter.
• If you have an interior shut-off valve for your outdoor spigots, turn it off. Then, open the outdoor spigot to let any remaining water drain out.

2. Insulate, Insulate, Insulate

Think of pipe insulation as a winter coat for your plumbing. It’s a cheap and effective way to protect vulnerable pipes in unheated areas.

What to do:

• Get foam sleeves: You can find pre-slit foam pipe insulation at any hardware store. They are simple to cut to size and fit over your pipes.
• Target the trouble spots: Focus on pipes in your crawlspace, attic, and unheated basement. Pay special attention to any pipes running along exterior walls.
• Don’t forget the fittings: Use foam tape or zip ties to secure the insulation, especially around corners and T-fittings.

3. Seal Up Air Leaks

Cold air is the enemy. Even small cracks or openings near your pipes can let in enough frigid air to cause a freeze.

What to do:

• Inspect your foundation: Look for any cracks or holes where pipes or utility lines enter your house.
• Seal the gaps: Use caulk or expanding foam spray to seal these openings from the inside and outside. This not only protects your pipes but also improves your home’s energy efficiency.

Emergency Actions During a Deep Freeze

When the weather report predicts an arctic blast, it’s time to take some immediate defensive measures.

1. Let Your Faucets Drip

It might seem wasteful, but a dripping faucet is your single best defense against a frozen pipe. Moving water is much harder to freeze than stationary water. The slight trickle keeps water flowing through the system and relieves pressure build-up inside the pipes if ice does start to form.

What to do:

• Choose the faucet furthest from where the water enters your house.
• Turn on both the hot and cold lines to a slow, steady drip (about 5-10 drips per minute is plenty).
• This small investment in your water bill is nothing compared to the cost of a burst pipe repair.

2. Open Cabinet Doors

Remember those pipes under your kitchen and bathroom sinks? Open the cabinet doors to allow warm air from the room to circulate around them. It’s a simple trick that makes a huge difference.

3. Keep Your Home Warm

If you’re heading out of town during a cold spell, don’t be tempted to turn your thermostat all the way down. Keep your heat set to at least 55°F. This ensures that enough ambient warmth reaches the walls where your pipes are located.

What to Do If a Pipe Is Already Frozen

You turn on the tap and only a trickle—or nothing—comes out. Don’t panic. Here’s how to handle a frozen pipe safely.

Step 1: Locate the Frozen Area
The freeze is likely located in one of the vulnerable areas mentioned earlier. Start with the faucet that isn’t working and trace the pipe back to the wall. The frozen section may have frost on it or feel significantly colder than the rest of the pipe.

Step 2: Keep the Faucet Open
Turn on the faucet that the frozen pipe leads to. As you thaw the pipe, the open faucet will allow melting water to escape and relieve the pressure inside.

Step 3: Gently Apply Heat
This is where you need to be careful. Never use an open flame, like a propane torch or a candle, to thaw a pipe. It’s a serious fire hazard and can damage the pipe itself.

Safe thawing methods:

• A hairdryer: This is the best and safest tool. Start at the end of the freeze closest to the faucet and work your way back toward the blockage.
• An electric heating pad: Wrap it around the frozen section.
• Hot towels: Soak towels in hot water, wring them out, and wrap them around the pipe.

Keep applying gentle heat until full water pressure is restored.

Step 4: Check for Leaks
Once the pipe is thawed, carefully inspect it for any new drips, cracks, or bulges. The expansion from the ice may have damaged the pipe, even if it didn’t burst completely.

When to Call a Professional Plumber

Some situations are best left to the experts. You should call Brian Wear Plumbing immediately if:

• You can’t find the frozen pipe.
• The pipe has already burst. Shut off the main water supply to your house immediately and then call us.
• You aren’t comfortable trying to thaw the pipe yourself.
• The water doesn’t come back on after attempting to thaw it.
