North Texas winters are deceptive. Discount Plumbing TX serves Wichita Falls and the surrounding 940 area, and freeze-related burst pipe calls are among the most common emergencies we handle. The city sits in a climate that swings from triple-digit summers to hard freezes that drop below 10°F — sometimes within days. Houses here are built primarily for heat, which means pipe runs that would be inside a conditioned wall in Minnesota are sitting in an uninsulated attic, an exterior wall cavity, or a garage in Wichita Falls.
When a hard freeze event hits — the kind that stalls over the region for three or four days — those pipes are exactly where burst pipe repair calls come from. This guide covers what actually happens to pipes in a freeze, which ones are most at risk in local homes, and the specific steps to protect them before the next cold event arrives.
Why Pipes Burst in a Freeze
The common explanation is that water expands when it freezes. That is true, but it is not the full picture of why pipes burst. What actually happens is this: when water in a pipe freezes, it creates an ice plug. The pressure that builds between the faucet and the ice plug — caused by water still flowing or sitting behind it — is what ruptures the pipe. The failure point is usually downstream of the freeze, not at the ice itself.
This matters for two reasons. First, a pipe can freeze without bursting if the pressure is allowed to equalize (which is why dripping faucets help). Second, the burst may not appear immediately. The pipe can crack during the freeze and not leak until it thaws — which is often the middle of the night, long after you thought the crisis had passed.
Which Pipes Are Most at Risk in Wichita Falls Homes
Not every pipe in your house carries equal freeze risk. In local homes, the highest-risk runs are predictable:
| Pipe Location | Freeze Risk | Why |
|---|---|---|
| Attic supply lines | High | Uninsulated, no heat source, extreme cold exposure from roof |
| Garage pipes (especially water heaters in garages) | High | Garage doors not airtight, temps track outdoor air closely |
| Exterior wall cavities | High | Insulation often on exterior side only, pipe exposed to cold |
| Outdoor hose bibs | Medium–High | Directly exposed; frost-free models fail if hose is still attached |
| Under-sink pipes on exterior walls | Medium | Cabinet door blocks heat from reaching pipes against exterior wall |
| Crawl space pipes (older homes) | Medium | Depends on whether crawl space is vented or enclosed |
| Interior supply lines, first floor | Low | Protected by conditioned space on multiple sides |
Older neighborhoods — Floral Heights, areas around downtown, streets near Midwestern State — tend to have more exposed runs than newer construction toward Southwest Parkway, where pipes are typically inside conditioned walls by design.
What Temperature Is Actually Dangerous
Pipes do not freeze at 32°F. They freeze when the sustained temperature inside the pipe space drops below 32°F for long enough for the water to lose heat. In practice, most burst events in this region happen when outdoor temps drop below 20°F and stay there for more than six hours. A single night at 28°F is usually survivable. Three nights at 12°F is not.
The danger in Wichita Falls is that freeze events often stall. The cold air mass sits. The structure of your house — walls, attic, garage — cools through progressively. A pipe that survived night one at 15°F may burst on night three because the surrounding structure has lost all its stored heat.
How to Protect Your Pipes: Step by Step
These steps are listed in order of importance. Do the high-priority ones first if a freeze is already incoming.
Know where your main shut-off valve is — and test it
If a pipe bursts while you are not home, or at 3 AM when you are asleep, the first thing you need to do is close the main. If you do not know where it is, or if the valve is stuck (common in older Wichita Falls homes), find a plumber to locate and service it before winter. A valve that takes two hands and ten minutes to close is not useful in an emergency.
Disconnect and drain all outdoor hoses
A hose left connected to an outdoor faucet traps water in the bib, defeating the frost-free design. Disconnect every hose, drain it, and store it before the first freeze. Frost-free hose bibs only work when empty — a connected hose fills them right back up.
Insulate exposed pipe runs in the attic, garage, and exterior walls
Foam pipe insulation is inexpensive and effective. Wrap any pipe you can reach in an attic, crawl space, or garage. Pay particular attention to supply lines within 12 inches of an exterior wall. Use foam tape at joints — gaps in insulation defeat the whole effort.
Let faucets drip during hard freeze events
Moving water freezes much more slowly than standing water. During events expected to drop below 20°F, open the faucets on your exterior walls to a slow drip — just enough to keep water moving. Focus on the faucets furthest from the water meter, as those have the longest runs. Hot and cold both.
Open cabinet doors under sinks on exterior walls
The cabinet under a kitchen or bathroom sink on an exterior wall acts as a cold box, blocking the warmth from the room. Open those doors during freeze events to let heated air circulate around the supply lines and drain.
Keep the thermostat at 55°F or above, even when away
If you leave town during a freeze event, do not turn the heat off. Keep it at a minimum of 55°F. The cost of running heat for a few days is a fraction of the cost of a single burst pipe and the resulting water damage.
Add heat tape to the highest-risk runs
Self-regulating heat tape plugged into an outdoor outlet is the most effective protection for attic supply lines and garage water heaters. It draws power only when the temperature around it drops — efficient and reliable. Have a plumber or electrician install it properly; the plug connection is where failures usually happen if done wrong.
Seal gaps in exterior walls where pipes enter
Cold air follows the same path water does. Gaps around pipe penetrations in exterior walls — typically sealed with spray foam or caulk — allow cold air to track directly to the pipe. Inspect these in the fall and reseal any that have cracked or pulled away.
What to Do If a Pipe Freezes (But Has Not Burst Yet)
If you turn on a faucet and get nothing, or a trickle, during a freeze event, you likely have a frozen pipe. Here is what to do — and what not to do:
Do:
- Open the faucet so pressure can escape as the ice melts
- Apply gentle heat — a hair dryer on low, a heating pad wrapped around the pipe, or warm towels — starting at the faucet end and working back toward the cold section
- Keep the main shut-off accessible in case the pipe has already cracked and you just cannot see it yet
Do not:
- Use an open flame, propane torch, or heat gun — these can damage pipe, melt solder joints, and start fires in wall cavities
- Apply heat in the middle of the frozen section first — pressure needs an exit point or it will blow the pipe
- Assume it thawed cleanly just because water is flowing — run a visual check on every visible inch of that pipe before you declare it safe
What to Do If a Pipe Bursts
- Close the main water shut-off immediately. Do not wait to assess the damage first.
- Cut breaker power to any circuit near standing water — without standing in the water to do it.
- Open the lowest faucet in the house to bleed remaining pressure out of the lines.
- Photograph everything before you move furniture or mop anything — your insurance company will need this.
- Call a licensed plumber. A burst pipe is not a DIY repair. The section needs to be cut out, the surrounding pipe inspected for additional cracks, and the repair pressure-tested before water is restored.
After the Freeze: What to Check
Once a freeze event passes and temperatures return above freezing, do a full walkthrough before you assume everything is fine:
- Walk through the house and check every ceiling and wall for wet spots, staining, or bubbling paint
- Check under every sink cabinet
- Look at the water heater, especially if it is in the garage — tank bodies can crack in extreme cold
- Check your water meter. Turn off every fixture and watch the dial. If it moves, you have a leak somewhere in the system
- Run water through every faucet and flush every toilet — watch for low pressure or discoloration that was not there before
When to Call a Plumber for Freeze Protection
Some freeze preparation is straightforward homeowner work — disconnecting hoses, opening cabinet doors, turning up the thermostat. Other parts genuinely require a licensed plumber:
- Servicing or replacing a stuck main shut-off valve
- Installing heat tape on attic or garage runs
- Repiping or rerouting a supply line that freezes every winter
- Insulating a crawl space pipe run that is not safely accessible
- Thawing a frozen pipe inside a wall
- Any burst pipe repair
