Winterizing your 5th wheel trailer is crucial to prevent costly damage from freezing temperatures. By following these steps, you can protect your investment and ensure your trailer is ready for adventures when warmer weather returns.
Understanding the Importance of Winterizing
Ignoring the process of winterizing your 5th wheel can lead to catastrophic consequences, including burst pipes, cracked fixtures, and damaged appliances. Water expands when it freezes, exerting immense pressure on plumbing systems and components. This can result in thousands of dollars in repairs and potentially render your trailer unusable. Proper winterization removes water from the system, replacing it with antifreeze or ensuring thorough drainage, thereby preventing ice formation and the associated damage. Investing the time and effort in winterizing is a small price to pay for the long-term protection of your 5th wheel.
Step-by-Step Guide to Winterizing Your 5th Wheel
The process of winterizing can seem daunting, but breaking it down into manageable steps makes it achievable for any RV owner. Here’s a comprehensive guide:
1. Preparation and Supplies
Before you begin, gather all the necessary supplies. This includes:
- RV antifreeze (non-toxic) – enough to fill all water lines and traps. (Quantity varies depending on trailer size; consult your owner’s manual or a local RV dealer).
- Water heater bypass kit (if not already installed) – simplifies the winterizing process.
- Water pump converter kit (or a fitting to connect antifreeze to the pump) – allows you to pump antifreeze through the system.
- Wrench set – for disconnecting and connecting fittings.
- Screwdriver set – for opening access panels and removing drain plugs.
- Air compressor with a blow-out adapter – to clear water lines with compressed air.
- Basin and towels – to catch any spills.
- Plumbing tape – to seal threads if needed.
- Gloves and safety glasses – for personal protection.
- Tank cleaner and sanitizer – To clean out your fresh water tank before winterizing
2. Drain the Water System
This is the most crucial step in the winterizing process. Begin by draining all water tanks:
- Fresh Water Tank: Locate and open the drain valve(s) for your fresh water tank. Allow the tank to drain completely.
- Grey and Black Water Tanks: Empty both grey and black water tanks at an appropriate dumping station. Thoroughly flush the black water tank to remove any remaining solids. Close the drain valves once completely emptied.
- Water Heater: Bypass the water heater (if equipped with a bypass kit). Remove the drain plug from the water heater and allow it to drain completely. Caution: Never drain the water heater while it’s hot or pressurized. Replace the drain plug with Teflon tape to prevent leaks.
- Water Lines: Open all faucets (hot and cold) throughout the 5th wheel, including the shower, toilet, and any outdoor faucets.
- Low Point Drains: Locate and open the low point drain valves. These are typically located under the trailer and allow water to drain from the lowest points in the plumbing system.
- Water Pump: Turn off the water pump and open a faucet to relieve pressure.
3. Blow Out the Water Lines
Using compressed air is an effective way to remove any remaining water from the lines:
- Connect an air compressor to the city water inlet using a blow-out adapter.
- Set the air compressor to a low pressure (around 30-40 PSI). Do not exceed 40 PSI to avoid damaging the plumbing.
- Open each faucet, one at a time, starting with the faucet closest to the water pump. Allow air to flow until only air comes out. Repeat this process for all faucets, showers, and the toilet.
- Remember to flush the toilet several times to clear the water lines leading to the toilet.
4. Introduce RV Antifreeze
After blowing out the lines, it’s time to introduce RV antifreeze:
- Bypass the water heater: Ensure the water heater bypass is engaged to prevent filling the water heater with antifreeze (this saves antifreeze and prevents potential contamination).
- Connect the water pump converter kit: Install the converter kit or fitting to allow you to draw antifreeze directly from the antifreeze container.
- Turn on the water pump: Turn on the water pump and open the faucets, one at a time, starting with the faucet furthest from the water pump. Run the pump until you see pink antifreeze flowing from each faucet.
- Flush the toilet: Flush the toilet until pink antifreeze appears in the bowl.
- Pour antifreeze into drains: Pour about a cup of antifreeze into each drain (shower, sinks) to protect the P-traps from freezing.
- Ice Maker/Water Dispenser (if applicable): Consult your appliance manual for specific winterizing instructions. Usually, this involves disconnecting the water line and cycling the ice maker or dispenser until antifreeze flows through.
5. Appliance Winterization
Don’t forget to winterize your appliances:
- Toilet: In addition to flushing with antifreeze, pour a generous amount of antifreeze into the toilet bowl.
- Shower and Sink Drains: Ensure antifreeze is in all P-traps.
- Washing Machine (if applicable): Consult the owner’s manual for specific winterizing instructions. Usually involves running a rinse cycle with antifreeze.
- Dishwasher (if applicable): Consult the owner’s manual for specific winterizing instructions. Usually involves running a rinse cycle with antifreeze.
6. Final Checks and Precautions
Before declaring your 5th wheel winterized, perform these final checks:
- Disconnect the battery: Disconnect the battery and store it in a cool, dry place. This prevents it from discharging during the winter.
- Propane Tanks: Turn off and disconnect the propane tanks.
- Seal any openings: Seal any openings or cracks in the trailer to prevent rodents from entering.
- Cover Tires: Cover the tires to protect them from UV damage.
- Consider a RV cover: If storing outdoors, consider using a RV cover to protect the trailer from the elements.
Frequently Asked Questions (FAQs)
1. Can I use regular automotive antifreeze in my 5th wheel?
Absolutely not! Regular automotive antifreeze is highly toxic and can contaminate your fresh water system. Always use non-toxic RV antifreeze specifically designed for potable water systems.
2. How much RV antifreeze do I need?
The amount of antifreeze needed depends on the size of your 5th wheel and the complexity of its plumbing system. A general rule of thumb is to have at least 2-3 gallons on hand for a smaller 5th wheel and 4-6 gallons for a larger one. It’s always better to have too much than too little.
3. Do I really need to bypass the water heater?
Yes, bypassing the water heater is crucial. It prevents you from filling the entire water heater tank with antifreeze, saving you money and preventing potential contamination of the water heater with antifreeze.
4. What if I don’t have an air compressor?
While using compressed air is recommended for thoroughly clearing the lines, you can still winterize without it. Simply rely on draining the system thoroughly and using a larger quantity of antifreeze to ensure all lines are protected. Consider having a professional do it if you are unsure.
5. Can I skip winterizing if I live in a mild climate?
Even in mild climates, temperatures can occasionally drop below freezing. It’s always better to be safe than sorry. The cost of winterizing is minimal compared to the potential damage caused by freezing.
6. How do I know if I’ve used enough antifreeze?
The best way to ensure you’ve used enough antifreeze is to observe the color of the fluid flowing from the faucets. It should be a consistent pink color, indicating that the antifreeze has reached all parts of the plumbing system.
7. What should I do if I accidentally get antifreeze in my fresh water tank?
If antifreeze accidentally gets into your fresh water tank, do not use the tank until it has been thoroughly cleaned and sanitized. Drain the tank completely and flush it several times with fresh water. Then, sanitize the tank with a bleach solution (1/4 cup of bleach per 15 gallons of water) and flush again. Consider consulting a professional for further assistance.
8. Is it safe to leave water in the toilet bowl during winter?
No, it’s not safe. Water left in the toilet bowl can freeze and crack the bowl or damage the flushing mechanism. Always add antifreeze to the toilet bowl during winterization.
