How Do You Winterize an RV Properly?

Winterizing your RV is more than just draining the water lines. It’s about preparing your home on wheels for freezing temperatures. This helps keep it in good shape until spring.

Improper winterization can lead to expensive damage, especially to the plumbing system and appliances.

Let’s go through a step-by-step guide that will help you winterize your RV properly.

Step 1: Drain the Water System Completely

Water is your RV’s biggest enemy during winter. If left in the pipes, it can freeze, expand, and cause serious damage. Here’s how to tackle the water system:

• Turn off all water pumps and disconnect external water sources.

• Open every faucet, valve, and showerhead—both inside and outside. This helps water drain from all lines.

• Don’t forget about the water heater. Make sure it’s cool, then open the drain valve and let it empty completely.

• Use an air compressor to blow out any remaining water from the system. Keep the pressure low to avoid damaging the pipes.

Step 2: Bypass the Water Heater and Add RV Antifreeze

To protect your RV’s plumbing, you need to add non-toxic RV antifreeze. Here’s the proper way to do it:

1. Install a water heater bypass kit to keep the antifreeze out of your water heater. This saves both time and antifreeze.

2. Pump antifreeze into your water lines. Turn on each faucet, one at a time, until you see pink antifreeze coming through. Don’t forget the toilet and outdoor shower, if you have them.

3. Check all drains. Make sure to pour some antifreeze down each drain to protect the traps.

Step 3: Protect the Exterior of Your RV

The outside of your RV needs just as much attention as the interior. Proper exterior maintenance will prevent rust, leaks, and other damage:

• Inspect the roof and seals. Look for cracks, peeling, or damage around vents, windows, and doors. Apply sealant where needed.

• Cover the RV properly. Use an RV-specific cover that’s breathable and waterproof. Avoid using tarps, which can trap moisture and cause mold.

• Tend to the tires. Inflate them to the recommended PSI and consider using tire covers to protect against freezing temperatures and sun damage. If possible, elevate the RV on jacks to reduce pressure on the tires.

Step 4: Safeguard the Appliances and Electronics

Winterizing the appliances in your RV is just as important as handling the plumbing. Extreme cold can damage wiring, screens, and internal components. Here’s what to do:

• Unplug and clean all appliances. Remove any perishable items, defrost the fridge, and prop the doors open to prevent odors.

• Disconnect batteries. Remove batteries from smoke detectors, clocks, and other small electronics. Store them somewhere safe and dry.

• Cover vents and use outlet covers to keep out rodents and pests.

Step 5: Manage Electrical Cords and Heavy Electronics

Beyond water and cold, electrical safety is another key aspect of RV winterization. Heavy electronics and improper cord storage can pose risks during long-term storage.

• Store cords properly. Wind up and secure any loose cords, and avoid wrapping them too tightly, which can damage the wiring. Use cable organizers or zip ties to keep everything in place.

• Use surge protectors. If your RV is stored with power connected, use a surge protector to prevent power surges from damaging sensitive electronics.

• Keep toddlers safe. If children are present, make sure cords are out of reach and secure heavy electronics. Outlet covers and safety locks are helpful in keeping curious hands away from dangerous spots.

Step 6: Keep Pests Away

One often overlooked aspect of winterizing is preventing pests from making your RV their winter home. Small animals and insects can cause significant damage. Here are some tips:

• Seal any small gaps or openings. Check around vents, windows, and the underside of the RV.

• Remove any food items. Even dry goods can attract critters. Clean out cupboards thoroughly.

• Use natural repellents. Consider placing dryer sheets, peppermint oil, or mothballs in key areas to deter rodents.

Step 7: Prepare the Interior for Storage

Your RV’s interior can also benefit from a little preparation before closing it up for the season:

• Remove all bedding, curtains, and cushions to prevent moisture buildup and mildew.

• Use moisture absorbers or dehumidifiers to keep the air dry.

• Close the blinds and use sunshades to protect against UV damage if your RV will be stored outside.

Following these steps will help keep your RV safe during the cold months, prevent damage, and ensure you’re ready to hit the road when spring arrives. Take the time to do it right, and your RV will thank you when it’s time to get back to your adventures.
