Winterizing your travel trailer is crucial to protect it from the potentially devastating effects of freezing temperatures. Properly draining and safeguarding your plumbing system, battery, and appliances will prevent cracked pipes, damaged fixtures, and costly repairs when you’re ready to hit the road again. This guide provides a step-by-step approach to winterizing your RV, ensuring it survives the cold season unscathed.
Why Winterizing is Essential
Failing to winterize your travel trailer can lead to significant damage. When water freezes, it expands, potentially causing pipes to burst, water heaters to crack, and appliances to malfunction. These repairs can be expensive and time-consuming. Taking the necessary steps to winterize your RV is a worthwhile investment in its longevity and your peace of mind. Preventing freeze damage is the primary goal.
Step-by-Step Winterization Process
This section details the process for effectively winterizing your travel trailer. Gather all the necessary supplies beforehand to streamline the procedure. You will need items such as RV antifreeze, a water pump converter kit or hand pump, tools to disconnect water lines, and potentially compressed air.
1. Drain the Water System
Completely draining your water system is the first and most critical step. This includes the fresh water tank, water heater, and all water lines.
- Fresh Water Tank: Open the drain valve and allow the tank to empty completely.
- Water Heater: Turn off the water heater and allow it to cool. Then, remove the drain plug and allow the water to drain. Important: Before removing the drain plug, make sure the water heater is OFF and the water is cool to avoid scalding. Rinse the tank to remove any sediment. Replace the drain plug and consider using Teflon tape for a better seal.
- Water Lines: Open all faucets, both hot and cold, including the shower and toilet. Flush the toilet several times to empty the water from the bowl and holding tank.
2. Bypass the Water Heater
Bypassing the water heater prevents antifreeze from filling it, saving you money on antifreeze and extending the life of your water heater. Most RVs have a bypass valve system specifically for this purpose. Consult your owner’s manual for the location and operation of these valves. If your RV doesn’t have a bypass system, you’ll need to install a bypass kit.
3. Introduce RV Antifreeze
There are two common methods for introducing RV antifreeze into the plumbing system: using a water pump converter kit or using a hand pump.
- Using a Water Pump Converter Kit: This is the preferred method. Disconnect the water intake line from the fresh water tank and connect it to the antifreeze container. Turn on the water pump and run each faucet (hot and cold) until pink antifreeze flows consistently. Don’t forget the shower and toilet. Flush the toilet until you see pink antifreeze. Turn off the water pump.
- Using a Hand Pump: Disconnect the water lines at the pump and attach the hand pump. Pump antifreeze through each faucet, shower, and toilet until pink antifreeze flows. Turn off the hand pump.
4. Protect Your Drains
Pour RV antifreeze down each drain (shower, sinks, and toilet) to protect the P-traps from freezing. This prevents sewer gas from entering the RV and protects against potential damage. About a cup of RV antifreeze is usually sufficient for each drain.
5. Disconnect and Store the Battery
Disconnect the battery cables and fully charge the battery before storing it in a cool, dry place. Lead-acid batteries will self-discharge over time, so check and recharge them periodically during the winter months. Proper battery maintenance is essential to prolong its lifespan.
6. Other Essential Winterization Steps
- Empty Holding Tanks: Thoroughly empty and flush the black and gray water holding tanks.
- Seal Openings: Seal any openings in the RV, such as vents and windows, to prevent drafts and pests from entering.
- Remove Food and Perishables: Remove all food items, including canned goods, to prevent attracting rodents and insects.
- Clean and Cover the RV: Clean the interior and exterior of the RV. Consider covering it with a breathable RV cover to protect it from the elements.
- Tires: Cover tires to protect them from UV rays. Consider placing the trailer on blocks to relieve pressure on the tires.
- Refrigerator: Empty and clean the refrigerator and freezer. Leave the doors slightly ajar to prevent mildew growth.
Frequently Asked Questions (FAQs)
This section addresses common questions regarding winterizing a travel trailer.
1. What kind of antifreeze should I use?
Use only RV antifreeze, which is specifically formulated for potable water systems. Do not use automotive antifreeze, as it is toxic and can contaminate your water system. RV antifreeze is non-toxic and safe for use in your RV’s plumbing.
2. How much RV antifreeze do I need?
The amount of RV antifreeze needed depends on the size and complexity of your plumbing system. A typical travel trailer requires 2-3 gallons of RV antifreeze. It’s always better to have a little extra than not enough.
3. Can I use compressed air instead of RV antifreeze?
While using compressed air to blow out the water lines is helpful for removing residual water, it’s not a substitute for RV antifreeze. Compressed air alone cannot guarantee that all water is removed, especially in low points and P-traps. RV antifreeze provides an extra layer of protection against freezing. It’s best to use both methods for optimal winterization.
4. What if I have a washing machine or dishwasher in my RV?
Consult your appliance owner’s manuals for specific winterization instructions. Generally, you’ll need to run RV antifreeze through the appliance’s water lines and drain. Some appliances may require additional steps to prevent damage.
5. What if I have an ice maker?
Disconnect the water line to the ice maker and run RV antifreeze through it until pink antifreeze appears. Ensure the ice maker tray is empty.
6. How do I know if I’ve used enough RV antifreeze?
You should see pink antifreeze flowing consistently from each faucet, showerhead, and toilet. This indicates that the entire plumbing system is protected.
7. What happens if I forget to bypass the water heater?
If you forget to bypass the water heater, you’ll waste a significant amount of RV antifreeze filling the tank. While it won’t necessarily damage the water heater, it’s unnecessary and costly.
8. Can I use a de-humidifier during the winter?
Using a dehumidifier can help prevent moisture buildup inside the RV, which can lead to mold and mildew growth. It’s a good idea, especially in humid climates.
9. How do I winterize the exterior of my RV?
Wash the exterior of the RV thoroughly. Apply a wax or sealant to protect the paint. Inspect and reseal any cracks or gaps in the sealant around windows and doors. Use an RV cover to protect the RV from the elements.
10. What if I need to use my RV during the winter?
If you plan to use your RV during the winter, you’ll need to take extra precautions to prevent freezing. This includes using a heated water hose, skirting around the RV, and using space heaters. Keep the RV heated to at least 40 degrees Fahrenheit to prevent pipes from freezing.
11. Where can I find the drain valves for my fresh and waste water tanks?
The location of drain valves varies depending on the make and model of your RV. Consult your owner’s manual for specific locations. Typically, they are located underneath the RV, near the tanks.
12. How long does it take to winterize a travel trailer?
The time required to winterize a travel trailer depends on the size and complexity of the RV, as well as your experience level. A typical travel trailer can be winterized in 2-4 hours.
