Why Travel Trailer Winterization is Crucial

Ignoring travel trailer winterization can lead to severe and expensive damage. Water expands when it freezes, putting immense pressure on pipes, fittings, water pumps, and even the toilet. Cracks, bursts, and leaks are common results, leading to extensive repairs and potential mold growth. Taking the time to properly winterize your travel trailer is a small investment that can save you thousands of dollars. This RV winterizing guide will provide detailed winterizing camper steps to ensure your RV is ready for the cold.

When to Winterize Your Travel Trailer

The best time to winterize your travel trailer is before temperatures drop below freezing (32°F or 0°C) for an extended period. Even a short period of freezing temperatures can cause damage. If you live in an area with harsh winters, aim to winterize your travel trailer in the fall, before the first frost. Don’t wait until the last minute! Early freeze protection for RV is key.

Supplies You’ll Need for Travel Trailer Winterization

Before you begin, gather all the necessary supplies. Having everything on hand will make the process smoother and more efficient. Here’s a comprehensive list:

• RV Antifreeze: Non-toxic RV antifreeze (propylene glycol) is essential. Do not use automotive antifreeze – it is toxic and can contaminate your fresh water system. Calculate the amount you’ll need based on the length of your water lines and the size of your holding tanks. Two to three gallons is usually sufficient for a small to medium-sized travel trailer.
• Water Heater Bypass Kit (if not already installed): This kit allows you to bypass the water heater, saving you gallons of RV antifreeze.
• Water Pump Converter Kit or Tubing: This allows you to easily draw antifreeze into your water lines.
• Wrench: For removing drain plugs.
• Screwdriver: For various tasks.
• Teflon Tape: For resealing drain plugs.
• Air Compressor with Blowout Adapter: To blow out the water lines. A small, portable compressor will work fine.
• Tank Cleaning Wand (optional): To thoroughly clean your holding tanks.
• Gloves: To protect your hands.
• Bucket: To catch water and antifreeze.
• RV Winterizing Checklist: Keep track of the winterizing camper steps

Step-by-Step Travel Trailer Winterization Instructions: A Detailed RV Winterizing Guide

Follow these steps carefully to properly winterize your travel trailer and protect it from freezing temperatures. This RV winterizing guide provides a comprehensive approach to travel trailer winterization.

Step 1: Drain the Water System – How to Drain Water Lines in RV

1. Drain the Fresh Water Tank: Locate the fresh water tank drain valve (usually underneath the trailer). Open the valve and let the tank drain completely. You might also have a siphon tube to drain.

2. Drain the Water Heater: Important: Ensure the water heater is turned OFF and the water has cooled completely before draining. Remove the drain plug (usually a plastic plug located at the bottom of the water heater). Use a wrench if necessary. Open the pressure relief valve at the top of the water heater to allow air to enter and speed up the draining process.

3. Drain the Gray and Black Water Tanks: Empty and thoroughly flush both gray and black water tanks at a designated dump station. Consider using a tank cleaning wand to remove any remaining debris. A clean tank is less likely to freeze and crack.

4. Bypass the Water Heater: If your travel trailer has a water heater bypass kit, use it to isolate the water heater. This prevents antifreeze from filling the tank (which is unnecessary and wastes antifreeze). If you don’t have a bypass kit, you’ll need to fill the water heater with antifreeze, which requires 6-10 gallons. Installing a bypass kit is highly recommended for future winterizations.

Step 2: Blow Out the Water Lines – How to Drain Water Lines in RV

1. Connect the Air Compressor: Attach the blowout adapter to a city water inlet. Set the air compressor to a low pressure (around 30-40 PSI). Do not exceed 40 PSI to avoid damaging the plumbing.

2. Open Faucets and Fixtures: Open all faucets (hot and cold) in the travel trailer, including the shower, toilet valve, and outside shower (if applicable).

3. Blow Out the Lines: Turn on the air compressor and let it run until water stops coming out of the faucets. Start with the faucet closest to the water pump and work your way outwards.

4. Flush the Toilet: Hold down the toilet flush pedal until air comes out.

5. Repeat the Process: Repeat the blowing-out process several times, alternating between hot and cold sides of each faucet. This ensures that all water is removed from the lines.

6. Remove the Air Compressor: Once you’ve finished blowing out the lines, disconnect the air compressor.

Step 3: Add RV Antifreeze – Plumbing Winterization RV

1. Install Water Pump Converter Kit or Tubing: Locate your water pump. Install the water pump converter kit or attach a length of tubing to the water pump intake. Place the other end of the tubing into a gallon of RV antifreeze.

2. Turn on the Water Pump: Turn on the water pump. It will begin to draw antifreeze into the water lines.

3. Open Faucets and Fixtures: Open each faucet (hot and cold) one at a time, starting with the faucet closest to the water pump. Let the faucet run until you see pink antifreeze flowing out. Then, close the faucet. Repeat this process for all faucets, including the shower and outside shower.

4. Flush the Toilet: Flush the toilet until you see pink antifreeze in the bowl.

5. Pour Antifreeze into Drains: Pour a cup of RV antifreeze down each drain (shower, sinks) and into the toilet. This will protect the P-traps from freezing.

6. Turn off the Water Pump: Once you’ve finished adding antifreeze to all the lines, turn off the water pump.

Step 4: Water Heater Winterization

1. Inspect and Clean: After draining the water heater, inspect the tank for sediment buildup. Flush the tank with a water heater tank cleaning wand if necessary.

2. Replace the Drain Plug: Reinstall the drain plug, using Teflon tape to seal the threads.

3. Close Pressure Relief Valve: Ensure the pressure relief valve is closed.

Step 5: Other Important Winterizing Steps

1. Batteries: Disconnect the batteries and store them in a cool, dry place. Consider using a battery maintainer to keep them charged during storage.

2. Tires: Cover the tires to protect them from UV damage. Inflate them to the recommended pressure to prevent flat spots.

3. Propane Tanks: Turn off the propane tanks.

4. Refrigerator: Empty and clean the refrigerator and freezer. Leave the doors slightly ajar to prevent mold growth.

5. Cabinets and Drawers: Remove all food items to prevent pests. Leave cabinet and drawer doors slightly open to allow air circulation.

6. Seal Openings: Seal any openings where pests could enter, such as gaps around pipes and wiring.

7. Roof Inspection: Inspect the roof for any cracks or leaks and repair them.

8. Wash and Wax: Give your Travel trailer a good wash and apply wax to protect the exterior surface from the elements.

Step 6: Winterizing Appliances

• Washing Machine (if applicable): Consult the owner’s manual for specific winterization instructions. Usually involves draining water lines and adding antifreeze.
• Dishwasher (if applicable): Run a cycle with RV antifreeze.
• Ice Maker (if applicable): Disconnect the water line and drain the ice maker.

RV Storage Tips for Winter

Proper RV storage tips for winter are crucial for protecting your travel trailer from the elements and preventing damage.

• Cover the RV: Use a breathable RV cover to protect the travel trailer from snow, rain, and UV damage.
• Choose a Location: Store the travel trailer in a sheltered location, if possible. Avoid parking under trees that could drop branches or debris.
• Ventilation: Ensure adequate ventilation to prevent moisture buildup.
• Security: Take steps to secure the travel trailer from theft.
• Regular Checks: Check on the travel trailer periodically throughout the winter to ensure everything is in good condition.

Preventing RV Damage From Freezing: What to do if you suspect your RV has frozen

If you suspect your RV plumbing has frozen:

1. Do not turn on the water pump. This can cause pipes to burst.
2. Warm the RV: Use a space heater or other safe heating source to warm the interior of the RV.
3. Check for leaks: As the ice thaws, carefully inspect all plumbing fixtures for leaks.
4. Call a professional: If you find any leaks or suspect damage, contact an RV repair technician for assistance.
