Putting antifreeze in your RV's fresh water tank is crucial for protecting your system from freezing temperatures during winter storage. Improperly doing so, however, can lead to damage and costly repairs. This guide will walk you through the process safely and effectively. This is a crucial step to protect your RV investment.
Why Use Antifreeze in Your RV Fresh Water Tank?
Freezing temperatures can cause significant damage to your RV's plumbing system. Water expands when it freezes, potentially cracking pipes, water lines, and even your water tank itself. Using RV antifreeze (propylene glycol based) prevents this damage by lowering the freezing point of the water in your system. Never use automotive antifreeze (ethylene glycol) as it's toxic.
Understanding RV Antifreeze
RV antifreeze, also known as potable antifreeze, is specifically formulated for use in recreational vehicles and is non-toxic. It's designed to protect your plumbing system from freezing without harming you or your family. Always check the label to confirm it's specifically designed for RV systems.
Step-by-Step Guide: How to Winterize Your RV Fresh Water Tank
Before you begin, ensure your RV is completely drained of all water. This includes the water heater, water pump, and all water lines.
1. Locate Your Fresh Water Tank
Find your RV's fresh water tank. Its location varies depending on the RV model. Consult your RV's owner's manual if you're unsure.
2. Prepare the Antifreeze
Measure the correct amount of RV antifreeze. This is crucial; using too little won't offer sufficient protection, and using too much might be wasteful. The amount needed depends on your tank's capacity. Refer to your owner's manual or a reliable RV winterization guide for precise measurements based on your tank size.
3. Pouring the Antifreeze
Carefully pour the measured antifreeze into your fresh water tank. Use a funnel to prevent spills.
4. Running the System
Turn on your water pump and run water through all faucets and fixtures. This ensures the antifreeze reaches all parts of your plumbing system, including pipes and the water heater (if not bypassed). Continue running the system until the antifreeze comes out of all faucets.
5. Draining the Water Heater
Many RVs have a dedicated drain valve for the water heater. Open this valve to ensure the water heater is completely drained and filled with antifreeze.
6. Adding Antifreeze to Low-Point Drains (If Applicable)
Some RVs have low-point drains designed to allow complete draining. Pour antifreeze directly into these drains as well to ensure protection of the lines.
7. Final Check
After completing all steps, check all faucets and fixtures again to ensure antifreeze is flowing through. This confirms a complete winterization.
Important Considerations
- Bypassing the Water Heater: Many RVs allow you to bypass the water heater. This often simplifies the winterization process. Consult your owner's manual.
- Storing Your RV: Park your RV in a location protected from harsh weather conditions.
- Professional Winterization: If you're uncomfortable with this process, consider hiring a professional RV service center. They have the expertise and tools to ensure a thorough winterization.
Troubleshooting
If you encounter issues during the process, like antifreeze not flowing freely, double-check all connections and valves to make sure they're open and not clogged.
By following these steps meticulously, you can effectively protect your RV's plumbing system from freezing damage and ensure that your RV is ready for winter storage. Remember to always consult your owner's manual for model-specific instructions.
