Step-by-Step De-Winterizing Guide
This guide outlines a comprehensive, step-by-step approach to de-winterizing your travel trailer, ensuring you cover all essential areas.
1. Initial Inspection
Before you even think about touching the plumbing, conduct a thorough visual inspection of your entire travel trailer.
- Exterior Examination: Look for any signs of damage – cracks in the sealant around windows and vents, compromised roofing material, or any other structural issues. Pay close attention to areas that may have accumulated snow or ice.
- Interior Inspection: Check for evidence of leaks or moisture damage, particularly around plumbing fixtures and under cabinets. Examine ceilings and walls for water stains. Look for any signs of rodent infestation.
2. Plumbing System Revival
The plumbing system is arguably the most critical area to address during de-winterizing.
- Bypass Valves: Locate and return all bypass valves to their normal operating positions. These valves were likely turned to isolate the water heater during winterization.
- Drain and Flush the Antifreeze: Open all faucets (both hot and cold) and the low-point drains. Allow the antifreeze to completely drain from the system. This may take some time, so be patient. Connect your city water hose to the intake and flush the lines thoroughly until the water runs clear and free of any pink color or taste. Consider using a water filter while flushing.
- Water Heater Inspection: Remove the drain plug from the water heater and flush out any sediment. Inspect the anode rod and replace it if it is corroded or significantly diminished. Replace the drain plug with Teflon tape to prevent leaks. Do not turn on the water heater until it is completely full of water.
- Sanitize the Water System: Add a sanitizing solution (usually a solution of bleach and water) to the freshwater tank. Instructions for the correct concentration will be on the sanitizer bottle. Fill the tank, then turn on all the faucets until the solution runs through them. Let the solution sit in the system for several hours (typically 4-12 hours, consult product instructions). Finally, drain the tank and flush the system with fresh water until the bleach odor is gone.
- Check for Leaks: After re-pressurizing the system, carefully inspect all connections, faucets, and pipes for any leaks. Tighten connections as needed.
3. Electrical System Check
The electrical system requires careful attention to ensure safety and proper operation.
- Battery Inspection: Check the battery terminals for corrosion and clean them if necessary. Ensure the battery is fully charged. If the battery was stored separately, reconnect it.
- Shore Power Test: Plug the travel trailer into shore power and verify that all electrical components are functioning correctly. Test all lights, outlets, and appliances.
- Generator Inspection (if applicable): Check the oil level and air filter. Start the generator and let it run for a while to ensure it is operating smoothly. Consider adding a fuel stabilizer if the fuel is old.
4. Appliance Examination
Each appliance requires individual attention to ensure it’s ready for the season.
- Refrigerator: Clean the interior and exterior of the refrigerator. Ensure the door seals properly. Test the refrigerator to ensure it cools effectively on both AC and propane power.
- Stove and Oven: Clean the stove top and oven. Check the propane connections for leaks using a soapy water solution. Test the burners and oven to ensure they are functioning properly.
- Water Heater: As mentioned earlier, never turn on the water heater until it is completely full of water. Test the water heater to ensure it is heating water efficiently on both propane and electric power.
- Air Conditioner: Clean the air conditioner filter. Inspect the cooling fins for debris. Test the air conditioner to ensure it is cooling effectively.
5. Tire Maintenance
Tires are crucial for safe travel.
- Tire Inspection: Check the tire pressure and inflate to the recommended PSI (found on the tire sidewall). Inspect the tires for any signs of wear and tear, such as cracks or bulges.
- Wheel Bearing Check: It’s highly recommended to have the wheel bearings inspected and repacked by a professional at least annually. Neglecting this can lead to bearing failure and potentially dangerous situations.
6. LP Gas System Safety
Propane systems demand careful inspection.
- Leak Test: After connecting the propane tank, perform a leak test using a soapy water solution. Apply the solution to all connections and look for bubbles, which indicate a leak. Tighten connections as needed.
- Propane Tank Inspection: Inspect the propane tank for any signs of damage or corrosion. Ensure the tank is properly secured.
7. Final Touches
Don’t forget these often-overlooked details.
- Wash and Wax: Give your travel trailer a good wash and wax to protect the exterior from the elements.
- Clean the Interior: Vacuum and dust the interior to remove any accumulated dirt and debris.
- Check Safety Equipment: Ensure the smoke detector and carbon monoxide detector are functioning properly and have fresh batteries.
- Restock Supplies: Restock all necessary supplies, such as toilet paper, paper towels, and cleaning supplies.
Frequently Asked Questions (FAQs)
Here are some common questions about de-winterizing a travel trailer:
FAQ 1: Can I use regular antifreeze instead of RV antifreeze?
No. Never use automotive antifreeze in your RV’s plumbing system. Automotive antifreeze is highly toxic and can contaminate your water system, posing a serious health risk. Always use RV antifreeze, which is specifically designed for potable water systems and is non-toxic.
FAQ 2: How do I sanitize my freshwater tank?
Use a solution of one-quarter cup of household bleach per 15 gallons of water. Fill the tank, run the solution through all faucets, let it sit for 4-12 hours, then drain and flush with fresh water until the bleach odor is gone.
