How to Prevent Frozen Pipes During an Oklahoma Ice Storm
Oklahoma's hard freezes and ice storms can burst pipes and flood a home in minutes. Here's how to protect your plumbing before, during, and after a deep freeze — plus what to do if a pipe freezes.
Oklahoma winters have a way of lulling you into complacency and then dropping a brutal Arctic blast or ice storm on the metro with little warning. When temperatures plunge into the teens and single digits, unprotected pipes can freeze, and a frozen pipe is a burst pipe waiting to happen. A single break can release hundreds of gallons of water into your home in a matter of hours. The good news: most frozen-pipe disasters are preventable with a little preparation. Here’s the complete playbook.
Why pipes burst (it’s not what most people think)
It’s a common misconception that a frozen pipe bursts at the spot where the ice forms. In reality, the danger comes from pressure. As water freezes and expands, it pushes water ahead of it, building enormous pressure between the ice blockage and a closed faucet downstream. That trapped pressure is what ruptures the pipe — often at a point away from the actual ice. This is why simply letting faucets drip during a freeze is so effective: an open faucet relieves the pressure that does the damage.
Which pipes are most at risk
Not all pipes face equal danger. The most vulnerable are those exposed to the cold or running through unheated spaces:
- Pipes in unheated areas — garages, attics, crawl spaces, and exterior walls.
- Outdoor hose bibs and any irrigation or pool supply lines.
- Pipes under sinks on exterior walls, especially in kitchens and bathrooms.
- Plumbing in vacant or rarely used parts of the house.
Homes across the metro — from older Edmond homes with original plumbing to newer builds with long runs through unconditioned attics — all have their own weak points. Knowing yours is half the battle.
Before the freeze: prepare now
The best time to protect your pipes is before the cold arrives, ideally well before the first hard freeze of the season.
Insulate exposed pipes. Foam pipe insulation sleeves are inexpensive and easy to install on accessible pipes in garages, crawl spaces, and attics. Pay special attention to any pipe you can feel cold air reaching.
Disconnect and drain outdoor hoses. A connected hose traps water in the bib and the pipe behind it, creating a freeze point right at your exterior wall. Disconnect every hose, drain it, and store it. Consider insulated covers for the hose bibs themselves.
Seal cold-air leaks. Cold air finds pipes through gaps around the foundation, in the rim joist, and where utility lines enter the house. Sealing these drafts with caulk or foam keeps frigid air away from vulnerable plumbing.
Know where your main shutoff is. This is the single most important thing on this list. If a pipe does burst, the speed at which you can shut off the water determines whether you’re dealing with a mop-up or a renovation. Find your main shutoff valve now, make sure it turns freely, and make sure everyone in the house knows where it is. The American Red Cross winter guidance is a helpful general resource for cold-weather home readiness.
During a hard freeze: active protection
When the forecast calls for a deep freeze or ice storm, take these steps:
Let faucets drip. Open both hot and cold taps to a slow trickle on faucets served by vulnerable pipes — especially those on exterior walls and farthest from where water enters your home. Moving water is much harder to freeze, and the open faucet relieves pressure. The small water cost is trivial compared to a burst pipe.
Open cabinet doors. Open the cabinet doors under sinks, particularly on exterior walls, so your home’s warm air can reach the plumbing. If you have young children or pets, move any hazardous cleaners out first.
Keep the heat on and consistent. Don’t set the thermostat back at night during a hard freeze, and never turn the heat off when leaving — even on a trip. Keep the house at a steady, reasonable temperature so interior pipes stay warm. If you’re traveling, leave the heat no lower than 55°F.
Open interior doors. Let heat circulate to every room, including those you don’t use often, so no section of plumbing gets isolated in the cold.
If a pipe freezes but hasn’t burst
If you turn on a faucet and only a trickle (or nothing) comes out during a freeze, you likely have a frozen pipe. Act quickly, because a frozen pipe can burst as it continues to freeze:
- Keep the faucet open. As you thaw the pipe, running water helps melt the ice and relieves pressure.
- Apply gentle heat to the frozen section — a hair dryer, a space heater kept a safe distance away, or towels soaked in warm water. Start near the faucet and work toward the cold section.
- Never use an open flame. A blowtorch or propane heater is a fire risk and can damage the pipe.
- If you can’t locate or reach the frozen section, or if a pipe has already burst, shut off your main water valve and call a professional.
If a pipe bursts
Shut off the main water valve immediately — this is why finding it in advance matters so much. Then shut off the electricity to any affected area if water is near outlets or your panel, open faucets to drain the system, and call for emergency service. The faster the water is off, the less damage you’ll face.
This is exactly the kind of call we answer around the clock. A burst pipe at 2 a.m. during an ice storm doesn’t wait for business hours, and neither do we — a real person answers, and we get to you fast.
After the freeze: check for trouble
Once temperatures climb back up, walk your home and look for signs of damage that may have happened during the freeze: damp spots on ceilings or walls, reduced water pressure, or water stains near vulnerable pipes. Sometimes a pipe cracks during a freeze but only begins leaking once it thaws and water flows again. Catching it early limits the damage.
Frequently asked questions
At what temperature do pipes freeze? Pipes are generally at risk when the outside temperature drops to about 20°F or below, though exposed or poorly insulated pipes can freeze sooner. The longer the cold lasts, the greater the risk.
Should I leave faucets dripping all winter? No — only during hard freezes when temperatures are at or below freezing for an extended period. A slow trickle on vulnerable faucets during those events is the goal, not a constant all-season drip.
Does letting a faucet drip really prevent freezing? It helps significantly. The moving water resists freezing, and more importantly, the open faucet relieves the internal pressure that actually causes pipes to burst.
How much does a burst pipe cost to fix? The pipe repair itself is often modest; the expensive part is the water damage to floors, walls, and belongings. That’s why prevention and a fast shutoff matter so much — they keep a small problem from becoming a large one.
My pipes froze once — does that mean they’ll freeze again? Likely yes, unless you address the underlying exposure. A pipe that froze has a weak point in its protection. We can help identify it and recommend insulation, sealing, or rerouting to prevent a repeat.
