Dewinterizing your travel trailer is the crucial process of preparing it for a new season of adventure, ensuring all systems are functioning correctly after winter storage and preventing potential damage. It involves flushing antifreeze, inspecting for leaks, sanitizing the water system, and checking all mechanical and electrical components to guarantee a safe and enjoyable RV experience.
Understanding the Importance of Dewinterization
Skipping or rushing the dewinterization process can lead to significant problems down the road, including burst pipes, contaminated water, and malfunctioning appliances. Freezing temperatures can wreak havoc on your RV’s plumbing and other systems, and failing to properly address these issues before hitting the road can result in costly repairs and a ruined vacation. A thorough dewinterization, therefore, is a cornerstone of responsible RV ownership.
Step-by-Step Dewinterization Guide
This guide outlines a comprehensive approach to dewinterizing your travel trailer, ensuring it’s ready for your next adventure. Remember to consult your owner’s manual for specific instructions relevant to your RV model.
1. Safety First: Essential Preparations
Before you begin, ensure you’re working in a well-ventilated area, especially when dealing with antifreeze. Wear appropriate protective gear, including gloves and eye protection. Also, disconnect your RV from shore power and any external water sources.
2. Flushing the Water System
This is arguably the most critical step. The pink RV antifreeze used for winterization is non-toxic to humans but doesn’t taste good and shouldn’t be consumed in large quantities. You’ll need to thoroughly flush it out of your entire water system.
3. Bypass Your Water Heater
Ensure your water heater is bypassed before flushing. This prevents antifreeze from entering and contaminating it. The bypass valves are typically located near the water heater itself. Consult your owner’s manual if you’re unsure of their location or operation.
4. Flush the Cold and Hot Water Lines
Connect your RV to a potable water source. Open all faucets (both hot and cold), showerheads, and the toilet valve. Let the water run until it flows clear and free of pink coloration from all outlets. This process can take some time, depending on the length and complexity of your plumbing system. Remember to flush both indoor and outdoor showers and sinks.
5. Drain and Flush the Water Heater
Once the water lines are clear, it’s time to deal with the water heater. First, turn off the bypass valves so the water heater fills. Never turn on your water heater until it is completely full of water. Then, locate the drain plug, typically at the bottom of the water heater, and carefully remove it (remember, there may be water pressure). Flush the water heater tank to remove any sediment or debris that may have accumulated. You can use a water heater tank cleaning wand for a more thorough flush. Reinstall the drain plug, wrapping the threads with Teflon tape to prevent leaks.
6. Sanitize the Water System
Even after flushing, it’s essential to sanitize your entire water system to eliminate any potential bacteria or contaminants.
7. Prepare a Sanitizing Solution
Mix a solution of ¼ cup of household bleach per 15 gallons of water. This is a standard concentration for sanitizing RV water systems. Use a funnel to pour the solution into your RV’s freshwater tank.
8. Run the Solution Through the System
Turn on your water pump and open all faucets (hot and cold) until you smell bleach. Allow the solution to sit in the water lines for at least four hours, or preferably overnight, to effectively sanitize the system.
9. Flush Again
After the sanitizing period, drain and flush the freshwater tank with fresh water until the bleach smell is gone. Then, flush all faucets and showerheads until the water is clear and odorless.
10. Check for Leaks
While flushing and sanitizing, carefully inspect all plumbing connections, faucets, and fixtures for leaks. Tighten any loose fittings or replace damaged components. Pay particular attention to areas that were previously winterized, as these are more prone to leaks.
11. Inspect and Test Appliances
Now it’s time to check all your appliances.
12. Reconnect and Test the Battery
After being disconnected for the winter, reconnect your RV battery. Ensure the connections are clean and secure. Test the battery’s charge and condition. If it’s weak or damaged, consider replacing it.
13. Test the Electrical System
Reconnect your RV to shore power and test all electrical components, including lights, outlets, air conditioner, and refrigerator. Check the GFCI outlets by pressing the “test” button and ensuring they trip.
14. Inspect Propane System
Carefully inspect all propane lines and fittings for leaks. You can use a soapy water solution to check for bubbles around connections. Have a professional inspect and service the propane system if you are not comfortable doing it yourself. Test all propane-powered appliances, including the furnace, water heater, and stove.
15. Check Tires and Brakes
Inspect your tires for proper inflation, wear, and damage. Check the brakes and ensure they are functioning correctly. Consider having a professional inspect your brakes if you have any concerns.
16. Wash and Wax
Finally, give your travel trailer a thorough wash and wax to protect the exterior from the elements and keep it looking its best. Inspect the roof for any signs of damage and make any necessary repairs.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions about dewinterizing your travel trailer:
FAQ 1: Can I use regular antifreeze instead of RV antifreeze?
No, never use regular automotive antifreeze in your RV’s water system. Automotive antifreeze is highly toxic and can contaminate your water supply, making it unsafe to drink. Always use RV antifreeze, which is specifically designed for potable water systems and is non-toxic.
FAQ 2: How do I know if my water heater is bypassed?
The bypass valves are typically located near the water heater. When bypassed, the valves will direct the water flow around the water heater tank. Consult your owner’s manual for specific instructions and diagrams. There will generally be two or three valves that need to be in a specific position.
FAQ 3: What if I can’t get rid of the bleach smell after sanitizing?
If the bleach smell lingers, flush the system with fresh water multiple times. You can also add a small amount of baking soda to the freshwater tank, let it sit for a few hours, and then flush again.
FAQ 4: How often should I sanitize my water system?
It’s recommended to sanitize your RV water system at least twice a year, once in the spring after dewinterizing and again in the fall before winterizing. You should also sanitize if your RV has been sitting unused for a long period.
FAQ 5: What if I find a leak during the dewinterization process?
If you find a leak, immediately shut off the water supply. Inspect the connection to determine the cause of the leak. Tighten any loose fittings or replace damaged components. If the leak persists, consult a qualified RV technician.
FAQ 6: Do I need to remove the anode rod from my water heater?
Yes, it’s recommended to remove and inspect the anode rod in your water heater annually. The anode rod is designed to corrode instead of the water heater tank. If it’s severely corroded, replace it with a new one.
