Winterizing your RV is essential to protect it from freezing temperatures, which can cause damage to your plumbing, engine, and other systems. Proper winterization ensures that your RV stays in good condition during the off-season and is ready to hit the road again when warmer weather returns. Here’s a step-by-step guide on how to winterize an RV effectively.
Why Winterizing Your RV is Important
If you live in or travel through regions with freezing temperatures, failing to winterize your RV can lead to costly repairs. Water in the plumbing lines can freeze, expand, and cause pipes to burst. Other systems, like the engine or heating, may also be affected by the cold. By taking a few preventive measures, you can avoid these potential problems and keep your RV safe during winter storage.
Steps to Winterize Your RV
1. Drain the Water System
The most crucial step in winterizing your RV is getting rid of all the water in the system. Here’s how to do it:
- Drain Freshwater Tanks: Start by draining the freshwater holding tanks and the water heater.
- Open All Faucets: Turn on all the faucets (both hot and cold) and let them run until no water comes out.
- Flush the Toilet: Don’t forget to flush the toilet to remove any remaining water.
- Drain the Water Heater: Make sure the water heater is off and cooled down before you drain it. Open the drain plug and pressure relief valve to let the water out.
- Empty the Grey and Black Water Tanks: Dump the contents of the grey (sink/shower water) and black (toilet waste) tanks at an appropriate dumping station.
2. Bypass the Water Heater
After draining the water, you’ll want to bypass the water heater so it doesn’t fill with antifreeze. Most modern RVs have a bypass valve, but if yours doesn’t, you can install one. This step is crucial because RV antifreeze can damage your water heater if it gets inside.
3. Add RV Antifreeze
Now it’s time to add RV-specific antifreeze to the plumbing system. Unlike automotive antifreeze, RV antifreeze is non-toxic and designed for potable water systems.
- Use a Water Pump Converter Kit: If your RV doesn’t have a built-in system for adding antifreeze, you can use a water pump converter kit or hand-pump antifreeze into the system.
- Pour Antifreeze into the Pipes: Turn on the water pump and open each faucet (one at a time) until pink antifreeze comes out. This ensures that antifreeze has filled the pipes and protected them from freezing.
- Flush Antifreeze Through Toilets: Flush the toilet until you see antifreeze in the bowl.
- Shower and Outdoor Faucets: Don’t forget to winterize the shower and any exterior faucets as well.
4. Winterize Appliances
Winterizing goes beyond just the water system—certain appliances also need attention:
- Refrigerator: Defrost your refrigerator and leave the doors slightly open to prevent mold buildup.
- Air Conditioner: Clean the air conditioner filters and cover the unit to protect it from dirt and debris.
- Propane Tanks: Make sure propane tanks are turned off and disconnected.
5. Seal the RV
To keep your RV in great condition during winter storage, you’ll want to seal it up tightly to prevent pests, moisture, and cold air from entering.
- Check Seals and Caulking: Inspect all doors, windows, and seals for cracks or damage. Reseal any areas where the caulking has worn away.
- Cover Roof Vents: Close or cover the roof vents to prevent snow or debris from getting inside.
- Tire Covers: Protect your RV tires from freezing temperatures by covering them, especially if the RV is being stored outside.
6. Disconnect the Battery
Cold weather can drain your RV’s battery, so it’s a good idea to disconnect it before storing your RV.
- Store the Battery: If possible, store your battery in a warm, dry place for the winter. Be sure to charge it periodically to maintain its health.
- Shut Off the Main Power: Before disconnecting, make sure the main power switch is turned off to prevent any potential electrical issues.
7. Cover Your RV
Once everything inside the RV is winterized, it’s time to protect the exterior.
- Use an RV Cover: Invest in a breathable RV cover that will shield your vehicle from snow, ice, and other elements. Avoid tarps, as they can trap moisture and cause mildew or damage to the finish.
- Store in a Covered Area: If possible, store your RV in a covered area or an indoor storage facility for maximum protection.
How Often Should You Winterize Your RV?
If you plan on using your RV in freezing conditions throughout the winter, you’ll need to winterize it every time you store it between trips. Otherwise, winterize your RV before temperatures drop below freezing and leave it winterized until you’re ready to use it in the spring or when the weather warms up.
