How to De-Winterize a Travel Trailer

The winter months can be tough on a travel trailer. The cold weather, snow, and ice can wreak havoc on your trailer’s systems, making it difficult to use when the weather warms up again. That’s why it’s important to de-winterize your trailer before you put it away for the season.

De-winterizing your trailer is a relatively simple process, but it’s important to do it correctly to avoid damage to your trailer’s systems. In this article, we’ll walk you through the steps of de-winterizing your trailer, so you can be sure it’s ready to use when the weather warms up again.

Step 1: Disconnect the Water Lines

The first step in de-winterizing your travel trailer is to disconnect the water lines. This will prevent any water from freezing and bursting the pipes. To do this, you will need to find the water shut-off valves. These are usually located on the outside of the trailer, near the water inlet.

Once you have located the water shut-off valves, turn them off to stop the flow of water. Be sure to turn off both the hot and cold water valves.

Next, you will need to disconnect the water lines from the trailer. The water lines are usually located under the trailer, near the axles. You will need to use a wrench to disconnect the water lines from the trailer.

Once you have disconnected the water lines, you can drain the water from the tanks. To do this, you will need to find the drain valves on the tanks. These are usually located at the bottom of the tanks.

Open the drain valves and allow the water to drain out of the tanks. Be sure to catch the water in a bucket or other container.

Once the tanks are empty, you can close the drain valves.

Step 2: Drain the Water Tanks

The next step is to drain the water tanks. This will prevent any water from freezing and bursting the tanks. To do this, you will need to find the drain valves on the tanks. These are usually located at the bottom of the tanks.

Open the drain valves and allow the water to drain out of the tanks. Be sure to catch the water in a bucket or other container.

Once the tanks are empty, you can close the drain valves.

Step 3: Blow Out the Water Lines

The next step is to blow out the water lines. This will remove any water that may be left in the lines, which could freeze and damage the lines. To do this, you will need a compressor and a blow gun.

Connect the blow gun to the compressor and turn on the compressor. Hold the blow gun to the end of the water line and turn on the blow gun. The air from the compressor will blow out any water that is left in the lines.

Continue blowing out the water lines until no more water comes out.

Step 4: Open the Water Shut-Off Valves

The next step is to open the water shut-off valves. This will allow the water to flow back into the tanks.

Turn on the hot and cold water valves to allow the water to flow back into the tanks.

Step 5: Fill the Water Tanks

The next step is to fill the water tanks. This will help to prevent any condensation from forming inside the tanks.

Fill the water tanks with fresh water. Be sure to use a water hose that is rated for RV use.

Step 6: Inspect the Water Lines and Tanks

The final step is to inspect the water lines and tanks for any damage. Look for any leaks or cracks. If you find any damage, you will need to repair it before using the trailer again.

Once you have inspected the water lines and tanks, you are ready to use your travel trailer again.

Step 3: Open the Water Valves and Flush the Lines

Once you have drained the water heater, it’s time to open the water valves and flush the lines. This will help to remove any sediment or debris that may have built up during the winter months.

To do this, simply turn on the water at each faucet in your trailer, and let it run until the water runs clear. You may also need to flush the toilet a few times to clear the lines.

Once you’re sure that the lines are clear, you can close the water valves and turn off the water at the city or campground hookup.

Step 4: Clean the Holding Tanks

The holding tanks in your travel trailer are where the wastewater from the toilet and sink drain. Over time, these tanks can become clogged with sediment and debris, which can lead to problems such as foul odors and slow drainage.

To clean the holding tanks, you will need to:

1. Remove the holding tank caps.
2. Add a holding tank deodorizer and cleaner to each tank.
3. Flush the tanks with water until the cleaner is gone.
4. Allow the tanks to dry completely.

Once the tanks are clean, you can replace the caps and reconnect the holding tank hoses.

By following these steps, you can easily de-winterize your travel trailer and get it ready for another season of camping fun.

Here are a few additional tips to help you winterize your travel trailer:

  • If you live in an area with cold winters, it’s a good idea to winterize your trailer even if you don’t plan on using it during the off-season. This will help to protect the trailer from damage caused by freezing temperatures.
  • When you’re not using your trailer, it’s important to store it in a dry, well-ventilated area. This will help to prevent the growth of mold and mildew.
  • If you’re storing your trailer for an extended period of time, it’s a good idea to disconnect the battery and drain the fuel tank. This will help to prevent damage to the battery and fuel system.

By following these tips, you can help to keep your travel trailer in good condition and extend its lifespan.
