Texas may be known for its warm climate, but winter can still bring sudden cold snaps that test even the best plumbing systems. Freezing temperatures, high winds, and unpredictable weather can create problems such as burst pipes, reduced water pressure, and water heater strain. Preparing early helps protect your home and avoid costly emergencies when temperatures drop.
TX Hydrojet’s licensed Houston plumbers share practical steps homeowners can take to keep plumbing systems operating safely and efficiently through the cold season.
Why Winter Plumbing Preparation Matters
Many Texas homes are not designed for extended freezing conditions. Pipes often run through attics, exterior walls, or crawl spaces—areas with limited insulation. When cold air enters, standing water inside those pipes can freeze, expand, and cause cracks or bursts.
Taking preventive action before temperatures dip below freezing helps:
- Prevent pipe damage and costly water loss
- Protect water heaters and fixtures
- Maintain steady water pressure
- Avoid emergency repairs during severe weather
Routine maintenance also supports system longevity, keeping plumbing reliable year-round.
Tip 1: Insulate Exposed Pipes
The most effective way to prevent freezing is by insulating vulnerable sections of piping. Focus on:
- Attics, garages, and crawl spaces
- Outdoor hose bibs and supply lines
- Pipes located near exterior walls
Foam sleeves, fiberglass wrap, or heat-tape systems create a thermal barrier that keeps water moving even when air temperatures fall below 32°F.
For outdoor faucets, use protective covers once hoses are removed. TX Hydrojet recommends checking insulation annually to ensure it remains dry and secure.
Tip 2: Seal Drafts and Air Leaks
Cold air entering through gaps or unsealed areas around pipes accelerates heat loss. Inspect walls, floors, and foundation openings for leaks and seal them with caulk or expanding foam.
Pay special attention to spaces under sinks located on exterior walls—small drafts can make a significant difference. Keeping warm air inside these cabinets helps maintain a safe temperature for the pipes they contain.
Tip 3: Let Faucets Drip During Freezes
Allowing a slight trickle of water to flow through faucets during extreme cold keeps water moving and reduces freezing risk. Focus on fixtures connected to exposed lines or pipes running through unheated spaces.
Movement prevents static water from freezing and relieves pressure inside pipes if ice begins forming. Even a slow drip can help protect the entire system.
Tip 4: Open Cabinet Doors
When temperatures drop, open cabinets under kitchen and bathroom sinks to allow household heat to circulate around plumbing.
This simple step is especially useful overnight when indoor temperatures naturally cool. Combined with insulated walls, it can prevent freezing in pipes located along outer walls.
Tip 5: Disconnect and Drain Outdoor Hoses
Water left in hoses and outdoor spigots can freeze and expand into interior supply lines. Before the first major cold front:
- Disconnect garden hoses and drain them completely
- Close interior shut-off valves leading to outdoor faucets (if available)
- Open exterior valves briefly to drain remaining water
Once drained, cover the faucets with insulated caps. This protects the line and fixture from internal ice buildup.
Tip 6: Service Your Water Heater
Cold weather increases demand on water heaters, as incoming groundwater temperatures drop. A maintenance check ensures consistent performance and efficiency.
TX Hydrojet’s technicians recommend:
- Flushing sediment buildup to improve heating efficiency
- Testing the temperature-pressure relief valve
- Checking for rust, corrosion, or leaks around fittings
- Insulating hot-water pipes for faster delivery
A properly maintained water heater delivers steady hot water while minimizing energy costs through winter.
Tip 7: Know Where Your Main Shut-Off Valve Is
In the event of a burst pipe, shutting off the main water supply quickly prevents flooding and limits damage.
Locate the valve—often near the water meter, crawl space, or where the main line enters the home—and ensure it turns smoothly. Consider tagging it for quick access during emergencies.
Property owners may also benefit from installing an automatic shut-off system that detects leaks and cuts water flow automatically.
Tip 8: Schedule a Professional Plumbing Inspection
A pre-winter inspection helps identify small issues before cold weather amplifies them. TX Hydrojet’s Houston plumbers use camera diagnostics and pressure testing to locate potential weaknesses in:
- Underground sewer or drain lines
- Exposed or corroded water lines
- Valves and connection points
- Water heater performance
Addressing minor leaks, loose fittings, or low insulation coverage early can prevent mid-winter emergencies and water damage.
Tip 9: Maintain Proper Indoor Heating
Keeping indoor temperatures consistent protects both comfort and plumbing systems. During cold fronts:
- Set thermostats to at least 55°F, even when away
- Use ceiling fans on low in reverse mode to distribute warm air evenly
- Close garage doors to retain heat around interior lines
If your home includes a crawl space, maintaining some heat flow below the main floor also helps safeguard pipes routed through that area.
Tip 10: Prepare for Power Outages
Texas winters sometimes bring power interruptions during extreme weather events. Without power, heating systems and well pumps may stop functioning, increasing the risk of frozen lines.
Homeowners can prepare by:
- Keeping portable heaters or generators ready for temporary warmth
- Storing bottled water for essential use
- Shutting off the main water valve and draining interior lines if extended outages occur
Understanding your home’s plumbing layout allows for quick response in emergencies.
Additional Winter Plumbing Recommendations
Drain and Winterize Sprinkler Systems
Irrigation lines and backflow preventers can crack if water freezes inside. Professional winterization includes blowing compressed air through the system to clear residual water.
Inspect Sump Pumps and Drains
Ensure sump pumps operate correctly before winter storms. Remove debris from drain grates and discharge lines to prevent freezing and overflow during thaw cycles.
Check Exterior Cleanouts
Keeping cleanouts accessible makes emergency service faster if a line backup occurs during cold weather.

Emergency Response
If a freeze causes a burst or backup, TX Hydrojet provides 24-hour service throughout Houston and surrounding areas to restore plumbing functionality quickly and safely.
Why Texas Homes Face Unique Winter Risks
Unlike northern climates where plumbing is built for long freezes, many Texas systems run close to exterior walls or through unconditioned spaces. A single night of sub-freezing temperatures can cause problems if pipes are unprotected.
Additionally, Texas weather can change rapidly. Sudden temperature drops leave little time for reaction. Having a plan in place ensures homeowners can respond quickly when cold fronts move in.
TX Hydrojet’s local expertise helps residents anticipate these conditions and prepare effectively.
How to Thaw Frozen Pipes Safely
If water stops flowing from a faucet during freezing weather, a pipe may already be frozen.
Steps to follow:
- Turn off the main water valve immediately to prevent leaks once the line thaws.
- Open nearby faucets to relieve pressure.
- Warm the frozen section gradually using a hair dryer or space heater—never an open flame.
- Once water resumes, check for leaks or bulges along the line.
Contact a professional plumber if the location of the frozen section isn’t accessible. TX Hydrojet’s team can safely locate and thaw frozen lines while minimizing damage.
The Importance of Ongoing Maintenance
Preventive maintenance is the most reliable defense against cold-weather plumbing failures. Annual inspections, insulation renewal, and timely repairs create a resilient system capable of handling both everyday use and seasonal extremes.
Consistent attention to plumbing health also supports water conservation, energy efficiency, and long-term property value.
Final Thoughts
Preparing for winter in Texas means anticipating sudden drops in temperature and protecting vulnerable plumbing components before problems occur. Insulating pipes, maintaining water heaters, checking valves, and scheduling professional inspections are simple but powerful steps toward preventing costly damage.
TX Hydrojet’s Houston plumbers provide the expertise and preventive care Texas homeowners need to keep water flowing smoothly through every season. With the right maintenance plan, your plumbing system remains efficient, reliable, and ready for whatever weather the winter months bring.
Winter Plumbing FAQs
Do Texas homes really need pipe insulation?
