As the fall season sets in, it’s crucial to start thinking about winterizing your RV. Early action ensures you have ample time to safeguard your vehicle from potential internal and external damage during the approaching snowy season. Whether you’re a novice RVer or a seasoned camper, this guide provides step-by-step instructions on how to winterize your travel trailer effectively.
Two Approaches to Winterizing: Antifreeze and Air Compressor
Before diving into the methods, let’s take a look at the essential tools and materials you’ll need for a successful winterization process.
To Winterize RV With Antifreeze, You Will Need:
- Non-toxic antifreeze (about 4 gallons) or an air compressor and blow-out plug
- A tool kit with a socket wrench (1-1/16”), ½” male pipe thread fitting (or quick connect fitting)
- Screw gun
- Channel locks
- Blow-out plug
- Teflon tape or Rectorseal
- Water pump converter kit
- Towels
Method 1: Winterize RV with Antifreeze
Step 1: Empty All Tanks
Ensure all electric elements are turned off before starting. Drain the freshwater tank, black water tank, galley, gray tanks, and the water heater tank. Use channel locks to remove the water heater’s plug and drain it, sealing the plug with Teflon tape or Rectorseal.
Step 2: Bypass the Water Heater
Work on the three valves in the water heater bypass to redirect cold water and prevent it from entering the water heater.
Step 3: Bypass the Fresh Water Tank
Locate the winterization valve or use a water pump converter kit to bypass the freshwater holding tank. Disconnect the tank’s lines from the water pump.
Step 4: Put Antifreeze into the System
Use a screw gun to access the water pump, disconnect it from the fresh water tank, and connect it to the fitting. Insert the fitting into the antifreeze jug and turn on the water pump with all faucets closed.
Step 5: Turn On Hot and Cold Water Faucets
Turn on faucets one by one until the water turns pink, indicating antifreeze flow. Repeat for toilet bowl, tub, and showerheads. Turn off the water pump, and pour remaining antifreeze into drains.
Method 2: Winterize RV with Air Compressor
Step 1: Empty All Tanks
Similar to the antifreeze method, begin by emptying all tanks, including draining the water heater with the relief valve and plugging it securely.
Step 2: Bypass the Water Heater
Follow the same procedure as in the antifreeze method to bypass the water heater using three valves.
Step 3: Set Up Your Air Compressor
Adjust the air compressor pressure to 30-40 PSI. Remove inline filters, attach the blow-out plug to the water inlet, and connect the air compressor.
Step 4: Turn On Hot and Cold Water Faucets
Turn on faucets until only air comes out, ensuring the air compressor expels all water. Do the same for toilet bowl, tub, and showerheads.
Step 5: Pour Antifreeze into the Drain
Complete the process by pouring a gallon of antifreeze into drains to protect p-traps from freezing.
Helpful Tips for Winterizing Your RV
- Protect Tires: Use tire covers to shield your RV tires from winter elements.
- Battery Care: Remove batteries and store them in a dry place. Use a battery tender to prevent draining.
- Insulate Windows and Doors: Enhance insulation and ensure all openings are sealed.
- Prevent Mold: Place natural dehumidifiers to avoid mold buildup.
- Electrical Appliances: Unplug all electrical appliances.
- Interior Cleaning: Give your RV’s interior a thorough cleaning.
Conclusion
Properly winterizing your RV is essential for protecting it from potential damage. The choice between antifreeze and air compressor methods depends on your location and desired level of protection. Whether you’re a beginner or an experienced RVer, this guide equips you with the knowledge to navigate the winterization process successfully. Safe travels, and thank you for reading!
