How Do You De Winterize a Travel Trailer?

De winterizing a travel trailer is important to prevent damage to the plumbing and other systems. This process involves draining all of the water from the trailer, treating the water lines with antifreeze, and lubricating the moving parts. It is a relatively simple process, but it is important to do it correctly to protect your trailer.

Gather Your Supplies

Before you begin de winterizing your travel trailer, you will need to gather the following supplies:

• Antifreeze
• Water hose
• Bucket
• Pliers
• Wrench
• Rags
• Penetrating oil

Drain the Water

The first step in de winterizing your travel trailer is to drain all of the water from the system. To do this, you will need to open all of the faucets in the trailer and let the water run until it stops. You will also need to locate the water drain valve and open it. This valve is usually located near the bottom of the trailer, on the outside. Allow all of the water to drain out of the trailer.

Once all of the water has drained out, you will need to close the drain valve. Be sure to tighten the valve securely to prevent any water from leaking back into the trailer.

Treat the Water Lines with Antifreeze

The next step is to treat the water lines with antifreeze. This will help to protect the pipes from freezing and cracking. To do this, you will need to pour antifreeze into the water lines. You can use a garden hose to do this, or you can use a pump. Be sure to fill the water lines completely with antifreeze.

Once the water lines have been filled with antifreeze, you will need to close the valves at the end of the lines. This will prevent the antifreeze from leaking out.

Lubricate the Moving Parts

The final step in de winterizing your travel trailer is to lubricate the moving parts. This will help to prevent them from rusting or seizing up. To do this, you will need to apply a light coat of penetrating oil to all of the moving parts, such as the door hinges, the window latches, and the wheel bearings.

Once you have lubricated all of the moving parts, you are finished de winterizing your travel trailer.

De winterizing your travel trailer is an important process that will help to protect your trailer from damage. By following these steps, you can ensure that your trailer is ready for next season.

Here are some additional tips for de winterizing your travel trailer:

• Be sure to read the owner’s manual for your trailer to get specific instructions on how to de winterize it.
• If you are not comfortable de winterizing your trailer yourself, you can take it to a dealer or RV service center.
• De winterizing your trailer is a good time to clean it inside and out.
• Once you have de winterized your trailer, be sure to store it in a dry, protected location.

By following these tips, you can keep your travel trailer in good condition and ready for your next adventure.

3. Flush the Water Lines

Once you have drained the water from the holding tanks, it is time to flush the water lines. This will help to remove any sediment or bacteria that may have built up in the lines during the winter.

To flush the water lines, you will need a garden hose and a bucket.

1. Connect the garden hose to the water inlet valve on the outside of the trailer.
2. Turn on the water supply to the trailer.
3. Place the bucket under the end of the garden hose.
4. Open the faucets in the trailer to allow the water to flow through the lines and into the bucket.
5. Continue to flush the lines until the water runs clear.
6. Turn off the water supply to the trailer.

4. Inspect the Plumbing

Once you have flushed the water lines, it is important to inspect the plumbing for any leaks or damage. This can be done by looking for any signs of water dripping or pooling under the trailer. You should also check the faucets and drains to make sure they are working properly.

If you find any leaks or damage, you will need to repair them before you can use the trailer again.

5. Refill the Holding Tanks

Once you have inspected the plumbing and repaired any leaks or damage, you can refill the holding tanks. To do this, you will need to connect a garden hose to the water inlet valve on the outside of the trailer. Turn on the water supply to the trailer and allow the tanks to fill up.

6. Reconnect the Water Line to the City Water Supply

Once the holding tanks are full, you can reconnect the water line to the city water supply. To do this, turn off the water supply to the trailer and disconnect the garden hose from the water inlet valve.

7. Purge the Air from the Water Lines

Once the water line is reconnected to the city water supply, it is important to purge the air from the lines. This can be done by opening the faucets in the trailer and allowing the water to run until it is clear.

8. Test the Plumbing

Once you have purged the air from the water lines, you should test the plumbing to make sure it is working properly. To do this, turn on the faucets in the trailer and make sure that they are all working properly. You should also check the drains to make sure they are draining properly.

9. Winterize the Trailer Again

Once you have de-winterized the trailer, it is important to winterize it again before you store it for the winter. This will help to protect the trailer from damage and prevent the growth of mold and mildew.

To winterize the trailer, you will need to:

• Drain the water from the holding tanks.
• Close the water inlet valve.
• Disconnect the water line from the city water supply.
• Open the drain valves on the underbelly of the trailer.
• Add antifreeze to the holding tanks.
• Add a chemical deodorizer to the holding tanks.
• Close the drain valves on the underbelly of the trailer.

By following these steps, you can de-winterize your travel trailer and prepare it for use again. This will help to protect your trailer from damage and ensure that it is ready to hit the road when the weather warms up.
