Winterizing your RV is crucial to prevent costly damage from freezing temperatures. One vital step is adding RV antifreeze to your fresh water tank. This guide provides a step-by-step process to ensure you do it correctly and safely. Improper winterization can lead to burst pipes and expensive repairs, so follow these instructions carefully.
Why Use Antifreeze in Your RV Fresh Water Tank?
Water expands when it freezes. This expansion can cause pipes, tanks, and other components within your RV's plumbing system to crack or burst, leading to significant damage and repair costs. RV antifreeze, specifically designed for this purpose, lowers the freezing point of the water in your system, protecting it from freezing damage even in sub-zero temperatures.
Choosing the Right Antifreeze
It's essential to use RV antifreeze, also known as propylene glycol antifreeze. Do not use automotive antifreeze (ethylene glycol), as it's toxic and harmful if ingested. RV antifreeze is non-toxic and safe for use in potable water systems – once flushed out properly.
Step-by-Step Guide: Adding RV Antifreeze to Your Fresh Water Tank
Before you begin, make sure you have the following:
- RV antifreeze (propylene glycol): Purchase enough to fill your fresh water tank completely.
- Funnel: To make pouring the antifreeze easier and cleaner.
- Gloves: To protect your hands from the antifreeze.
- Water hose: For later flushing.
Here's how to add antifreeze to your RV's fresh water tank:
-
Empty the Fresh Water Tank: Completely drain your fresh water tank by opening the drain valve located at the bottom of the tank.
-
Locate the Fresh Water Tank Fill: Identify the opening where you typically fill your fresh water tank with a hose.
-
Pour in the Antifreeze: Using a funnel, carefully pour the RV antifreeze into the fresh water tank fill opening. Ensure the tank is completely filled.
-
Run the Water System: Turn on all faucets and showerheads to circulate the antifreeze throughout the plumbing system. This will push the antifreeze through all lines and prevent freezing. Let it run until the antifreeze comes out of all faucets.
-
Winterize remaining Components: Remember that the antifreeze only protects the lines it flows through. You'll likely need to add antifreeze to other areas of your RV's water system, such as low-point drains. Consult your RV's owner's manual for specific instructions.
Flushing Your System in Spring
After winter, before using your RV again, it is absolutely crucial to thoroughly flush your system to remove all traces of the antifreeze.
-
Flush with Clean Water: Fill the fresh water tank with clean water and run all faucets until the water runs clear and free of pink antifreeze residue. This may require several rounds of flushing.
-
Check all Faucets and Showerheads: Ensure that clear water comes out of all faucets and showerheads before using the water for drinking or cooking.
Important Considerations
-
Consult your Owner's Manual: Always refer to your RV's owner's manual for specific instructions regarding winterizing your RV's fresh water system. Procedures may vary between models.
-
Protect Yourself: Always wear gloves when handling RV antifreeze.
-
Proper Disposal: Dispose of any used antifreeze according to local regulations.
By following these steps, you can effectively protect your RV's plumbing system from freezing damage and extend the life of your RV. Remember, proper winterization is an essential part of RV ownership. Don't skip this step!
