Winterizing a trailer house, also known as a manufactured home, is crucial to prevent costly damage from freezing temperatures, including burst pipes, damaged appliances, and even structural issues. This process involves draining water systems, insulating vulnerable areas, and taking proactive steps to protect your investment from the harsh realities of winter.
Why Winterizing is Essential
The primary reason to winterize a trailer house is to prevent water damage. When water freezes, it expands. This expansion can rupture pipes, damage fixtures, and cause significant problems that are expensive to repair. Furthermore, failing to winterize can lead to increased energy bills due to heat loss and potential damage to the home’s structure itself. Neglecting this essential task can result in a habitable, comfortable living space becoming a frozen, costly nightmare.
Step-by-Step Winterization Process
Here’s a breakdown of the key steps involved in properly winterizing your trailer house:
1. Disconnecting and Draining the Water System
This is the most critical step. If any water remains in your pipes, it’s practically guaranteed to freeze and cause damage.
- Shut off the Main Water Supply: Locate the main water shut-off valve and turn it off. This is usually located near the water meter or where the water line enters the property.
- Drain the Water Heater: Turn off the power or gas supply to the water heater before draining it. Connect a hose to the drain valve (usually located at the bottom of the tank) and run it to a low point outside, such as a drain or ditch. Open the drain valve and let the water drain completely. Once drained, close the valve.
- Open All Faucets and Flush Toilets: Open all hot and cold water faucets inside the trailer house, including those in the sinks, shower, and bathtub. Flush all toilets multiple times. This helps to relieve pressure and allows water to drain from the lines.
- Bypass the Water Heater: If your water heater has a bypass kit, use it. This allows you to circulate antifreeze through the plumbing without filling the water heater tank. If you don’t have a bypass kit, you can install one, or carefully drain the water heater as outlined above.
- Drain the Holding Tanks (if applicable): If your trailer house has holding tanks (common in RV-style trailers), drain them completely. Use the dump valves to empty the tanks and then flush them with fresh water.
- Blow Out the Water Lines: Use an air compressor to blow out any remaining water in the lines. Connect the compressor to the water inlet and set the pressure to around 30-40 PSI. Open each faucet and toilet individually, allowing air to push out any remaining water.
- Add RV Antifreeze: Pour non-toxic RV antifreeze into the drains of sinks, showers, and toilets. This will protect the P-traps from freezing. Pour enough antifreeze into the toilet bowl to cover the bottom.
2. Insulating Vulnerable Areas
Proper insulation is crucial for preventing heat loss and protecting pipes from freezing.
- Skirting: Ensure your trailer house has adequate skirting. This helps to insulate the underbelly and prevent cold air from circulating beneath the home. Repair any damage to the existing skirting.
- Pipes: Wrap exposed pipes with pipe insulation. This includes pipes under sinks, in crawl spaces, and along exterior walls. Heat tape can be used in particularly cold areas, but use it with caution and follow the manufacturer’s instructions carefully.
- Windows and Doors: Seal any cracks or gaps around windows and doors with caulk or weather stripping. Consider covering windows with plastic sheeting or insulated curtains to further reduce heat loss.
- Underbelly: Inspect the underbelly insulation and repair or replace any damaged or missing sections.
3. Protecting Appliances and Fixtures
Taking specific steps to protect appliances and fixtures will prevent damage.
- Appliances: Clean out refrigerators and freezers. Prop the doors open to prevent mildew growth. Disconnect and drain dishwashers and washing machines.
- Toilets: As mentioned before, add RV antifreeze to the toilet bowl and tank. This prevents the remaining water from freezing and cracking the porcelain.
- Septic System: If you have a septic system, have it inspected and pumped if necessary. This ensures it’s functioning properly before winter.
4. Additional Winterization Tips
- Rodent Control: Take measures to prevent rodents from entering your trailer house. Seal any holes or cracks and set traps.
- Ventilation: Ensure adequate ventilation to prevent moisture buildup. Open windows slightly on warmer days.
- Roof: Inspect the roof for any leaks or damage and repair them promptly. Snow and ice can exacerbate existing problems.
- Gutters: Clean out gutters to prevent ice dams from forming.
Frequently Asked Questions (FAQs)
FAQ 1: What type of antifreeze should I use?
You should only use non-toxic RV antifreeze specifically designed for potable water systems. Never use automotive antifreeze, as it is highly toxic and can contaminate your water supply.
FAQ 2: How do I blow out the water lines if I don’t have an air compressor?
While an air compressor is the most effective method, you can try using a hand pump or even a shop vacuum (used as a blower). However, these methods are less effective and may not remove all the water. Consider borrowing an air compressor if possible.
FAQ 3: Can I just leave a faucet dripping to prevent freezing?
While a dripping faucet can help, it’s not a reliable solution in extremely cold temperatures and can waste a significant amount of water. It’s much safer and more effective to properly winterize the entire water system. Furthermore, in many areas a dripping faucet will still freeze solid in extremely cold temperatures, defeating its purpose.
FAQ 4: How much RV antifreeze do I need?
The amount of antifreeze needed depends on the size of your plumbing system. A few gallons should be sufficient for most trailer houses. Follow the instructions on the antifreeze container for specific recommendations.
FAQ 5: Do I need to winterize my trailer house if I only leave it vacant for a few weeks?
If temperatures are expected to drop below freezing, it’s always best to err on the side of caution and winterize your trailer house, even for a short period. The cost of winterizing is far less than the cost of repairing frozen pipes.
FAQ 6: What if my trailer house has a well water system?
Winterizing a trailer house with a well water system requires additional steps. You may need to insulate the well pump and pipes, and consider adding heat tape if necessary. Consult with a well water specialist for specific recommendations.
FAQ 7: How do I winterize a washing machine in a trailer house?
After disconnecting the water lines and draining the hoses, pour RV antifreeze into the detergent dispenser and run a short spin cycle to distribute the antifreeze throughout the pump and internal lines.
FAQ 8: What about the water filter?
Remove the water filter cartridge and discard it. Store the empty housing in a warm place to prevent cracking. Some people pour RV antifreeze into the empty housing as well.
FAQ 9: How can I tell if my pipes are frozen?
If you turn on a faucet and no water comes out, or if the water pressure is significantly reduced, your pipes may be frozen. If you suspect frozen pipes, do not use an open flame to thaw them. Use a hair dryer or heat tape, and contact a plumber if the problem persists.
FAQ 10: Can I use regular home insulation to insulate my pipes?
While regular insulation can provide some protection, pipe insulation is specifically designed to prevent freezing and condensation. It’s more effective and easier to install on pipes.
FAQ 11: How often should I check on my winterized trailer house?
Ideally, you should check on your winterized trailer house every few weeks, especially after periods of extreme cold. Look for any signs of damage, such as leaks or cracks.
FAQ 12: What if I have solar panels connected to my trailer house?
If your trailer house has solar panels, ensure they are properly maintained and free from snow and ice. Disconnect them from the electrical system if you’re not using them. Consult with a solar panel specialist for specific winterization recommendations.
Conclusion
Winterizing your trailer house is an investment in its longevity and your peace of mind. By following these steps and addressing the common concerns outlined in the FAQs, you can protect your home from the damaging effects of freezing temperatures and ensure a comfortable and worry-free winter. Remember, a little preparation can go a long way in preventing costly repairs down the road.
