How to Keep Pipes from Freezing in a Manufactured Home
When winter temperatures plummet, one of the biggest headaches for manufactured homeowners is frozen pipes. Unlike site-built homes, manufactured (or mobile) homes often have plumbing that runs under the home or in less insulated spaces, making pipes more vulnerable to freezing. The good news? With the right precautions and ongoing care, you can keep your water flowing even in the coldest months.
Let’s break down everything you need to know about preventing frozen pipes in your manufactured home, from essential steps to reliable tips, common pitfalls, and answers to frequently asked questions.
Why Do Pipes Freeze in Manufactured Homes?
Manufactured homes are unique in their construction. Water lines often run beneath the home, where cold air can circulate freely if not properly protected. When the temperature drops below freezing, water inside exposed pipes can freeze, expand, and eventually cause the pipes to burst. This leads to costly repairs and water damage.
Key factors that contribute to pipes freezing include:
- Lack of or damaged insulation around pipes and underbellies
- Skirting with gaps or missing panels
- Unheated crawl spaces
- Sudden drops in temperature
Essential Strategies to Prevent Pipes from Freezing
Protecting your home’s plumbing requires a mix of preparation and ongoing vigilance. Here are the most effective ways to safeguard your pipes through harsh winters:
1. Insulate Pipes Thoroughly
Pipe insulation is your first line of defense. Insulation slows down the loss of heat from the water inside the pipes.
How to do it:
- Use foam pipe insulation sleeves or wrap pipes with heat tape
- Focus on main water lines, exposed pipes, and joints
- Secure insulation with zip ties or tape for a snug fit
Pro tip: Check insulation annually, especially before cold weather hits. Replace any areas showing wear or gaps.
2. Enclose the Underside with Quality Skirting
Proper skirting acts like a coat for the underside of your home, protecting pipes from icy winds.
Best practices:
- Install insulated, well-sealed skirting panels around your home
- Inspect skirting for holes, cracks, or missing panels and repair promptly
- Avoid using flimsy materials—durable, weatherproof skirting lasts longer
Benefits:
Skirting also prevents pests from taking up residence beneath your home and helps retain heat.
3. Use Heat Tape on Vulnerable Pipes
Electric heat tape is designed to keep pipes safely above freezing.
How to apply heat tape:
- Wrap the tape along the length of the exposed pipe, following the manufacturer’s guidelines
- Avoid overlapping the tape, as this can create hot spots
- Secure the tape, then plug it into a GFCI-protected outlet
- Consider automatic heat tape with a built-in thermostat for added efficiency
Warning:
Check that heat tape is safe for your pipe material (PVC vs. copper) and replace old, frayed, or malfunctioning tape.
4. Seal Air Leaks and Drafts
Cold air sneaking under your home or through utility holes can quickly freeze pipes.
What to do:
- Seal gaps around piping, vents, and wiring with expanding foam or weather stripping
- Check the area where water lines enter the home for leaks
- Block off high-wind areas with additional insulating panels
5. Keep a Consistent Heat Source
Even a few degrees can make a difference below your home.
Options:
- When it’s very cold, let indoor faucets drip slightly to keep water moving
- Leave cabinet doors open under sinks to let warm air around the pipes
- Use a small, safe space heater in the crawl space for extreme weather (monitor closely for safety)
6. Protect Your Water Supply Entry Point
The place where the main water line enters your home is a high-risk zone.
Best tips:
- Insulate the entry point both outside and inside
- Build a small enclosure for added warmth, or wrap exposed valve assemblies with extra insulation
- Check these areas frequently during cold snaps
Benefits of Taking Preventative Action
- Prevents broken pipes and expensive repairs
- Keeps your water running all winter
- Protects your home against water damage
- Reduces risk of mold and mildew from leaks
- Improves the energy efficiency of your home
Challenges and How to Overcome Them
1. Hard-to-Reach Areas
Sometimes, pipes are tucked into tight areas under your home. Use long-handled tools and bright lighting to spot vulnerable spots. Consider hiring a pro for particularly tricky insulation jobs.
2. Old or Damaged Materials
If your insulation, skirting, or heat tape is old or broken, it may not work as intended. Regularly inspect all materials each fall. Replace or upgrade as needed.
3. Power Outages
Heat tape and heaters won’t work in a power outage. In severe cold, shut off the main water supply and drain lines if you expect to be without power for an extended period.
Practical Tips for Winter Pipe Protection
- Do a pre-winter walkthrough: Check insulation, skirting, seals, and pipe condition every year.
- Label your main shut-off valve: If a pipe bursts, you’ll need to act fast.
- Have plumbing supplies on hand: Heat tape, extra insulation, pipe repair materials, and towels—keep them stocked for emergencies.
- Keep an eye on weather reports: When extreme cold is forecast, take extra precautions—open taps, check heat tape, monitor temperatures under your home.
- Don’t forget outdoor spigots: Insulate or cover hose bibs and drain them in the fall.
Common Mistakes to Avoid
- Relying solely on heat tape without insulation
- Ignoring skirting repair needs
- Using indoor-grade materials outdoors
- Turning off home heating entirely during cold spells
- Failing to check pipes after a hard freeze or thaw
What to Do if Pipes Freeze
If you turn on the tap and nothing happens, your pipes may be frozen. Quick action can prevent a burst:
- Turn off the main water supply to prevent flooding if the pipe bursts.
- Locate the frozen section—often in crawl spaces, near walls, or by the skirting.
- Gently warm the pipe using a hairdryer, heating pad, or warm towels. Never use open flames.
- Check for leaks as ice melts.
- Once thawed, turn the water supply back on and inspect for any damage.
If you can’t locate or reach the frozen section, or if a pipe bursts, it’s time to call a licensed plumber.
Frequently Asked Questions (FAQs)
1. How cold does it have to get before my pipes might freeze?
Even temperatures just below 32°F (0°C) can freeze exposed pipes within hours, but the risk goes up the longer it stays freezing. Manufactured homes are especially susceptible if the pipes are uninsulated or exposed.
2. Can I use regular home insulation to wrap pipes?
Special foam pipe sleeves or insulation wraps are best. Standard fiberglass insulation can work in a pinch but isn’t as effective or durable in damp spaces beneath your home.
3. What should I do if I’m going away for the winter?
Shut off the main water supply, drain the system, and flush toilets. Leave heat tape on exposed pipes and inform a neighbor or trusted friend to check your home during cold spells.
4. How often do I need to replace skirting or insulation under my home?
Inspect annually and after severe weather. Quality skirting and insulation can last many years, but damage from wind, animals, or moisture may require earlier replacement. Catch problems early for the best results.
5. Are heating cables safe to use under my home?
Heating cables or heat tape are safe if installed and maintained properly. Use products designed for your specific pipe type, never overlap cables, and check regularly for wear or malfunction.
Key Takeaways
Protecting your manufactured home from frozen pipes is all about preparation and consistency. Thorough insulation, secure skirting, smart use of heat tape, and prompt action during cold snaps will keep your water system safe and reliable year after year. By staying proactive and following these steps, you’ll enjoy peace of mind and save money on costly winter repairs.
