Winter is right around the corner here in the Maritimes! Winterizing your RV is essential to protecting it from Canada’s freezing temperatures to ensure that your systems stay in good working condition. Don’t miss these key steps:

1. Drain the Water System

• • Drain the Fresh Water Tank: Open the tank drain valve and let all the water out. You may need to open the faucet inside to allow air to flow and help it drain completely.
  • Drain the Water Heater: Be sure to turn off the water heater and let it cool down before draining it. Open the drain valve at the bottom of the heater to let the water out.
  • Drain All Water Lines: Open all faucets (hot and cold), including the shower, to let the remaining water out of the lines. Don't forget the outdoor shower, if you have one.
  • Empty the Holding Tanks: Drain the black and gray water tanks. Open the dump valve and flush until the tanks are empty.

2. Blow Out the Water Lines

• • Use an air compressor to blow out any remaining water from the pipes and water lines. Make sure to blow air through all faucets, including the shower and toilet. This step helps to prevent any water from freezing inside the pipes, which could cause them to burst.

3. Add Antifreeze to the Plumbing System

• • Use RV Antifreeze (non-toxic): After blowing out the water lines, you need to add RV antifreeze to protect the plumbing system from freezing.
  • Bypass the Water Heater (if applicable): If your RV has a water heater, make sure to bypass it (many RVs have a bypass valve kit installed) so you don’t waste antifreeze in the water heater tank.
  • Add Antifreeze to the Plumbing System: Pour antifreeze into the fresh water tank (following the manufacturer’s recommendations for the amount). Then, turn on the water pump and open each faucet, including the toilet and shower, until you see the antifreeze come through. Do this for both hot and cold lines.
  • Toilet: Don't forget the toilet—flush antifreeze down into the holding tank to protect the seals from freezing.

4. Protect the Exterior

• • Clean the RV: Wash and wax the exterior of your RV to protect the paint and surfaces from salt, dirt, and moisture.
  • Cover Vents and Openings: Cover roof vents, windows, and any other exterior openings with vent covers or plastic sheeting to keep moisture and cold air from entering.
  • Cover Tires: Protect your tires from the sun and cold by covering them or using tire covers. This will help prevent cracking and damage.

5. Disconnect and Store the Batteries

• • Remove the Batteries: Disconnect and remove the RV batteries to prevent them from freezing and potentially being damaged. Store them in a cool, dry place, and periodically check the charge throughout the winter.
  • Clean the Battery Terminals: Before storing the batteries, clean the terminals to prevent corrosion.

6. Check the Roof and Seals

• • Inspect the roof for any signs of damage, cracks, or leaks. Apply roof sealant as necessary. Check around all windows, doors, and any other openings for cracked or worn seals and replace them to prevent water from entering.

7. Protect Interior Areas

• • Prevent Freezing in the Cabin: You can use moisture-absorbing products like silica gel packs or dehumidifiers to reduce moisture and prevent mold growth inside the RV.
  • Cover Upholstery: If your RV will be in storage for the winter, consider covering the furniture to protect it from dust and moisture. Use breathable covers or sheets to avoid trapping moisture underneath.

8. Check the Propane System

• • Close the Propane Tank Valves: Turn off all propane appliances and close the valves on the propane tanks. If possible, remove the propane tanks and store them in a safe, well-ventilated area away from the RV.
  • Inspect the Propane System: Check hoses and connections for any leaks or wear, and repair or replace as needed.

9. Storage Location

• • Store the RV in a Shelter (if possible): If you can, store your RV in a garage, carport, or RV cover to protect it from the elements. If storing outside, use an RV cover to shield it from snow, ice, and wind.
  • Elevate the RV (Optional): If you're storing your RV long-term, consider using RV jacks or blocks to lift the RV off the ground slightly to avoid flat spots on the tires.

10. Inspect Everything Before You Go

• • Before winterizing, double-check everything and make sure all steps are completed. A full inspection now will save you headaches come spring when you de-winterize and get your RV ready to go.

Winterizing your RV may seem like a lot of work, but it’s a critical step in protecting your investment and ensuring it’s ready to hit the road when the weather warms back up. Taking the time to do it thoroughly will save you from expensive repairs down the line.
