How to Winterize Your RV

As the temperatures drop and winter approaches, it’s crucial to prepare your RV for the cold months ahead. Winterizing your RV not only protects it from damage caused by freezing temperatures but also ensures it’s ready for your next adventure when spring arrives. In this blog post, we’ll guide you through the steps to properly winterize your RV.

1. Drain and Bypass the Water System

The first step in winterizing your RV is to drain all water from the system to prevent pipes and tanks from freezing and cracking.

• Drain the Freshwater Tank: Begin by emptying the freshwater tank. Open the drain valve and allow all water to flow out.
• Drain the Water Heater: Turn off the water heater and let it cool. Open the drain plug and pressure relief valve to drain the water heater completely.
• Drain the Grey and Black Water Tanks: Ensure that your grey and black water tanks are fully emptied at a dump station. Clean and flush the tanks to remove any residue.
• Bypass the Water Heater: Most RVs have a bypass valve for the water heater. Engage the bypass to prevent antifreeze from entering the water heater.

2. Blow Out the Water Lines

To further protect your water system, it’s essential to remove any remaining water from the lines.

• Use an Air Compressor: Attach an air compressor to the city water inlet. Set the compressor to a low pressure (around 30-40 PSI) to avoid damaging the pipes.
• Open Faucets: Starting with the faucet furthest from the compressor, open each faucet one at a time to blow out any remaining water. Don’t forget to include the outdoor shower, if your RV has one.
• Flush the Toilet: Blow out any water in the toilet by holding down the flush pedal.

3. Add RV Antifreeze to the System

RV antifreeze is non-toxic and designed specifically for winterizing RV water systems. It prevents any remaining water in the system from freezing.

• Pour Antifreeze into the System: Using a water pump converter kit or by disconnecting the inlet side of the water pump, pump antifreeze into the water system. Begin by pouring the antifreeze into the freshwater tank or directly into the water lines.
• Open Faucets: Starting with the closest faucet to the pump, open each faucet one by one until pink antifreeze flows through. Repeat this process for all faucets, showers, and toilets.
• Don’t Forget the Drains: Pour a small amount of antifreeze into each drain to protect the P-traps.

4. Protect Your Batteries

Cold weather can reduce the lifespan of your RV’s batteries if they’re not properly maintained.

• Disconnect the Batteries: If possible, remove the batteries from the RV and store them in a cool, dry place. If you’re leaving the batteries in the RV, disconnect them to prevent any drain.
• Charge the Batteries: Fully charge the batteries before storing them. Check the charge periodically throughout the winter, and recharge as necessary to prevent them from freezing.

5. Seal and Protect the Exterior

Protecting the exterior of your RV from harsh winter conditions will help prevent damage and keep it in top shape.

• Inspect the Seals: Check all windows, doors, and seams for any cracks or gaps. Use RV-specific sealant to repair any areas that could allow moisture to seep in.
• Cover Your RV: Invest in a breathable RV cover that will protect your RV from snow, ice, and UV rays. Ensure that the cover fits properly to prevent wind damage.
• Protect the Tires: Inflate the tires to the recommended pressure and cover them to protect against the cold. If possible, move the RV slightly every few weeks to prevent flat spots.

6. Winterize the Interior

Taking steps to protect the interior of your RV will ensure it’s ready to go when spring arrives.

• Remove Perishables: Clear out all food, beverages, and other perishables from the RV to avoid attracting pests or dealing with unpleasant odors.
• Clean and Vacuum: Thoroughly clean the interior of the RV, including vacuuming carpets and wiping down surfaces. This will help prevent mold and mildew growth during storage.
• Leave Doors Open: Leave the doors of cabinets, closets, and the refrigerator slightly open to allow air circulation and prevent musty odors.

Conclusion

Winterizing your RV is an essential part of RV ownership, especially if you live in a region with freezing temperatures. By following these steps, you can protect your RV from winter damage and ensure it’s ready for your next adventure. Proper winterization not only extends the life of your RV but also gives you peace of mind during the off-season.
