The Comprehensive Step-by-Step Guide: How to Winterize an RV for Winter Living

This section provides a detailed how to winterize an RV for winter living guide , breaking down the process into manageable steps. Follow these instructions carefully to ensure your RV is fully protected.

1. Draining the Water System Thoroughly

This is the foundational step. You must remove all water from your tanks and lines.

  1. Empty Freshwater Tank: Open the low-point drain for your freshwater tank and let it completely empty.
  2. Drain Hot Water Heater: Turn off your water heater (electric and propane). Allow it to cool. Open the pressure relief valve at the top, then remove the drain plug at the bottom to drain it. If you have an anode rod, inspect it and replace it if necessary.
  3. Empty Black and Grey Tanks: Dump and flush your black and grey water tanks thoroughly at a dump station. Use a tank rinser if available.
  4. Open All Faucets and Low-Point Drains: Open both hot and cold water faucets in your kitchen, bathroom sink, and shower. Don’t forget the outdoor shower and toilet flush valve. Locate and open all low-point drains (usually blue and red lines under your RV) to allow any remaining water to escape.

Pro Tip: After draining, close the hot water heater bypass valves (if installed) to prevent antifreeze from entering the tank. This saves antifreeze and prevents a strange taste in your hot water next season.

2. Blowing Out Water Lines with Compressed Air

Using an air compressor helps remove stubborn pockets of water that gravity alone might miss.

  1. Connect Blow-Out Plug: Screw an RV blow-out plug into your city water inlet.
  2. Set Compressor Pressure: Set your air compressor to no more than 30-40 PSI. Higher pressure can damage your RV’s plumbing.
  3. Blow Out Lines: Attach the air compressor hose to the blow-out plug. Systematically open one faucet at a time (hot and cold), starting with the one furthest from the compressor. Let the air push out the water until only air comes out.
  4. Repeat for All Fixtures: Go through all faucets, the toilet, and the outdoor shower. Don’t forget to flush the toilet several times.
  5. Close Drains and Faucets: Once all lines are clear, close your low-point drains and all faucets.

Safety First: Wear eye protection when working with compressed air. Ensure your pressure regulator is functioning correctly.

3. Adding RV Antifreeze (The Non-Toxic Kind!)

Antifreeze provides an extra layer of protection against freezing, especially in P-traps and hard-to-drain areas.

  1. Bypass Water Heater: Ensure your hot water heater is bypassed.
  2. Prepare Water Pump: If you have a water pump converter kit, attach the hose to the antifreeze container. If not, you may need to pour antifreeze into your freshwater tank (though this requires more antifreeze and takes longer to flush).
  3. Turn On Water Pump: Turn on your RV’s water pump. It will begin drawing antifreeze into the system.
  4. Open Faucets Systematically: Starting with the faucet closest to the pump, open the cold water until pink antifreeze comes out. Close it. Then open the hot water until pink antifreeze comes out. Close it.
  5. Repeat for All Fixtures: Continue this process for every faucet, shower head, and the toilet. Flush the toilet until pink antifreeze appears in the bowl. Don’t forget the outdoor shower!
  6. Pour Down Drains: Pour a cup or two of antifreeze directly down each sink and shower drain to protect the P-traps. Also, pour some into the toilet bowl to protect the flush valve and seal.

Expert Tip: Keep a close eye on your antifreeze supply. If you run out mid-process, you’ll need to start again from the last completely pink faucet.

4. Protecting Your RV’s Exterior and Undercarriage

Winterization isn’t just about plumbing. Your RV’s exterior needs attention too.

  • Tire Care: Inflate tires to recommended PSI. Cover them to protect from UV rays and harsh elements. Consider moving the RV slightly every few weeks to prevent flat spots.
  • Seal Slides and Seals: Inspect all slide-out seals, window seals, and door seals. Clean them and apply an RV-specific seal conditioner to prevent cracking in the cold.
  • Install RV Skirting: If you’re staying in extremely cold conditions, install RV skirting around the base. This dramatically reduces heat loss from the floor and protects plumbing lines in the underbelly.
  • Check Roof and Vents: Inspect your roof for any cracks or leaks. Seal them with appropriate RV sealant. Ensure roof vents are closed or covered to prevent heat loss and snow/ice intrusion.

5. Securing the Interior for Cold Weather Comfort

Once the plumbing is handled, focus on creating a warm and moisture-free living space. This is key for winter RV living tips.

  • Insulate Windows and Vents: Use foam board, reflective insulation, or heavy thermal curtains on windows. Vent insulators can be placed in roof vents.
  • Seal Gaps: Check around doors, windows, and utility access points for drafts. Use weatherstripping or temporary caulk to seal them.
  • Moisture Control: Condensation is a major enemy in winter RVs. Use a dehumidifier and moisture absorbers. Ensure good ventilation, even in cold weather, by cracking a window or vent occasionally.
  • Pest Prevention: Block any potential entry points for rodents or insects with steel wool or expanding foam. Remove all food items from cupboards or store them in airtight containers.
  • Battery Care: If you’re not connected to shore power, remove your RV’s house batteries and store them in a warm, dry place. Keep them charged with a trickle charger. If staying connected, ensure they are fully charged and maintained.
