Water System Winterization: The Crucial Step

This is arguably the most critical part of the process. Frozen water can destroy your RV’s plumbing. Follow these storing RV for winter best practices meticulously.

  1. Drain All Water Tanks: Empty your fresh water, grey water, and black water tanks completely. Flush the black tank thoroughly with a tank rinser if available.
  2. Bypass the Water Heater: Locate the bypass kit on your water heater and engage it. This prevents antifreeze from entering and filling the water heater, saving you several gallons.
  3. Drain the Water Heater: Open the drain plug (usually a plastic plug or anode rod) and let all water escape. Close the drain plug once empty.
  4. Open All Faucets and Low-Point Drains: Open hot and cold faucets, showerheads, and toilet valves. Open all low-point drains to ensure every drop of water exits the system.
  5. Use an Air Compressor (Optional but Recommended): Attach an air compressor (regulated to 30-50 psi) to your city water inlet. Blow out any remaining water from the lines until only air comes out of the faucets.
  6. Pump RV Antifreeze Through the System:
    • Ensure you use non-toxic RV/marine antifreeze. Never use automotive antifreeze.
    • Connect a bypass hose to your RV’s water pump and place the other end into a jug of antifreeze.
    • Turn on the water pump.
    • Starting with the faucet furthest from the pump, open the hot and then cold sides until pink antifreeze flows steadily.
    • Repeat for all faucets, shower, toilet, and outdoor shower. Don’t forget the toilet flush pedal.
    • Pour a cup or two of antifreeze down each drain (sinks, shower) to protect the P-traps.
    • Pour a small amount into the toilet bowl to protect the seal.

Engine and Chassis Care: Powering Down

Don’t forget the mechanical heart of your RV. Proper care here ensures your engine starts strong in the spring.

  • Battery Maintenance:
    • Remove house and chassis batteries.
    • Clean battery terminals thoroughly.
    • Store batteries in a cool, dry place.
    • Connect them to a trickle charger or battery tender to maintain a full charge throughout winter.
    • If leaving batteries in, disconnect the negative terminal to prevent parasitic drain.
  • Fuel System Protection:
    • Fill your fuel tank to at least 3/4 full to prevent condensation.
    • Add a fuel stabilizer to the tank and run the engine for a few minutes to circulate it.
  • Tire Care:
    • Inflate tires to their maximum recommended PSI to prevent flat spots.
    • Consider using tire covers to protect them from UV damage.
    • If possible, lift the RV off its tires using jacks or blocks to completely relieve pressure.
  • Engine Fluids: Check and top off all engine fluids, especially coolant, ensuring it’s rated for winter temperatures.
  • Exhaust System: Cover the exhaust pipe with steel wool or a rag to prevent pests from nesting inside.

Exterior Protection: Covering and Sealing

The exterior is your RV’s first line of defense against the elements.

  • Wash and Wax: Give your RV a thorough wash and apply a coat of wax. This protects the finish and makes spring cleaning easier.
  • Inspect and Seal: Check all seams, seals, and caulk around windows, doors, and the roof. Repair any cracks or gaps to prevent water intrusion.
  • Cover Vents and Openings: Cover all exterior vents (refrigerator, furnace, water heater) with screens or covers to deter pests.
  • Consider an RV Cover: A breathable, well-fitting RV cover offers excellent protection from snow, ice, UV rays, and dirt. Ensure it allows for air circulation to prevent moisture buildup.
  • Remove Propane Tanks: If storing indoors, remove propane tanks. If outdoors, ensure they are securely closed and covered.
  • Clear Roof: Remove any debris from the roof, and ensure gutters are clear to prevent water pooling.

Sustainable Storing RV for Winter: Eco-Friendly Practices

As outdoor enthusiasts, we care deeply about our planet. Incorporating sustainable storing RV for winter practices is not only responsible but also often more effective in the long run.

Choosing Non-Toxic Antifreeze

Always opt for RV/marine antifreeze that is explicitly labeled as non-toxic and biodegradable. These products are typically propylene glycol-based, making them safer for the environment and easier to dispose of responsibly.

Avoid any antifreeze containing ethylene glycol, which is highly toxic to humans and animals.

Responsible Waste Disposal

When draining your tanks or purging antifreeze, be mindful of where the waste goes. Never dump black or grey water directly onto the ground.

Dispose of all tank contents at a designated dump station. While RV antifreeze is non-toxic, it’s still best to dispose of larger quantities at an appropriate waste facility or pour it down a drain connected to a septic or sewer system, not directly into waterways.

Solar Panel Care

If your RV has solar panels, they can still generate a trickle charge even in winter. Keep them clean of snow and debris to maximize any available sunlight. This can help keep your batteries topped off if they remain connected and you have a charge controller. However, for long-term storage, removing batteries and using a dedicated tender is often more reliable.

Common Problems with Storing RV for Winter (and How to Avoid Them)

Even with the best intentions, things can go wrong. Being aware of common problems with storing RV for winter helps you anticipate and prevent them.

Burst Pipes and Tanks

Problem: Water left in lines, faucets, or tanks freezes, expands, and causes cracks. This is the most prevalent and damaging winterization mistake.

Solution: Thoroughly drain and blow out all water lines, then circulate non-toxic RV antifreeze through every part of the plumbing system. Don’t forget the toilet valve, outdoor shower, and ice maker lines.

Pest Infestations

Problem: Mice, rats, insects, and even larger critters seek warmth and shelter in your RV, gnawing through wires, nesting in fabrics, and leaving behind unsanitary messes. Solution: Remove all food, deep clean the interior, cover all exterior openings (exhaust, furnace, refrigerator vents), and seal any gaps or cracks. Place deterrents like dryer sheets, peppermint oil cotton balls, or commercial pest repellents strategically. Regularly check for signs of entry.

Battery Drain and Damage

Problem: Batteries left connected will slowly drain due to parasitic loads. Freezing temperatures can permanently damage a discharged battery. Solution: Remove batteries, clean them, and store them in a climate-controlled area on a smart trickle charger. If left in the RV, disconnect the negative terminal and ensure they are fully charged.

Mold and Mildew Growth

Problem: Trapped moisture and lack of air circulation create a breeding ground for mold and mildew, leading to unpleasant odors and potential health issues.

Solution: Ensure the RV is completely dry before storage. Use moisture absorbers, leave cabinet and refrigerator doors ajar, and ensure some ventilation if using a breathable cover. Check the RV periodically during storage for any signs of dampness.

Storing RV for Winter Best Practices: Pro Tips for Longevity

Beyond the basic steps, these storing RV for winter best practices offer insights from seasoned RVers, designed to extend your RV’s life and simplify spring de-winterization.

The Right Storage Location

Where you store your RV makes a big difference. An indoor, climate-controlled facility is ideal but often costly. A covered outdoor spot offers good protection from snow and UV. If storing uncovered outdoors, ensure the ground is level, well-drained, and away from overhanging trees that could drop branches or sap.
