Winterizing a living quarters horse trailer is essential for protecting your investment and ensuring a comfortable and functional space when the weather warms. Failure to properly prepare your trailer for freezing temperatures can lead to costly repairs from burst pipes, damaged appliances, and compromised structural integrity. This comprehensive guide, drawing on years of experience in trailer maintenance and cold-weather protection, will walk you through the necessary steps to safeguard your home on wheels.
Why Winterizing is Non-Negotiable
The primary reason to winterize is preventing water damage. When water freezes, it expands, potentially cracking pipes, fittings, and even holding tanks. This damage can be extensive and expensive to repair. Beyond plumbing, winterizing also helps protect other components like batteries, appliances, and the overall structure from the harsh effects of cold temperatures and moisture. Neglecting this crucial process can transform your dream trailer into a nightmare of repairs and lost investment.
Step-by-Step Winterization Process
This detailed procedure will cover all the critical areas of your living quarters horse trailer. Remember to consult your trailer’s owner’s manual for specific instructions and recommendations related to your particular model.
1. Drain the Water System
This is arguably the most important step. Residual water is the enemy.
- Drain the Fresh Water Tank: Locate and open the drain valve(s) on your fresh water tank. Allow all the water to drain completely.
- Drain the Water Heater: Turn off the water heater (both gas and electric) and allow it to cool completely. Remove the drain plug (usually located at the bottom of the tank) and let the water drain. Some water heaters have an anode rod; remove this to allow for thorough draining and inspect it for corrosion. Consider replacing it if necessary.
- Drain the Water Lines: Open all faucets (hot and cold) in the trailer, including the shower and any outdoor faucets. Locate the low-point drain valves (typically red and blue) and open them to drain the water lines. Use the water pump briefly to help push any remaining water out of the lines. Remember to open the toilet flush valve as well.
- Bypass the Water Heater: Before introducing antifreeze, you’ll want to bypass the water heater to avoid filling it with several gallons of antifreeze. Most trailers have a bypass valve or a series of valves that allow you to isolate the water heater. Refer to your owner’s manual for specific instructions.
2. Add RV Antifreeze
This food-grade antifreeze is specially formulated for plumbing systems and is non-toxic to humans and animals after proper flushing. Never use automotive antifreeze!
- Connect Antifreeze to Water Pump: Locate the water pump. There’s usually a winterizing kit with a hose that you can connect to a jug of RV antifreeze. If you don’t have a winterizing kit, you can disconnect the water pump’s inlet line and insert it directly into the jug.
- Pump Antifreeze Through the Lines: Turn on the water pump. Starting with the faucet furthest from the pump, open both the hot and cold sides until you see a steady stream of pink antifreeze. Repeat this process for each faucet, the shower, and the toilet. Don’t forget any exterior shower or faucet.
- Pour Antifreeze Down Drains: Pour about a cup of RV antifreeze down each drain (kitchen sink, bathroom sink, shower, toilet) and into the toilet bowl to protect the P-traps.
3. Protect Appliances and Other Components
Freezing temperatures can damage more than just the plumbing.
- Water Heater: Even after draining, some water may remain in the water heater. Consider removing the plug/anode rod and using compressed air to blow out any remaining water.
- Toilet: As mentioned above, add antifreeze to the bowl. Also, check the toilet valve and flush mechanism for any remaining water and apply antifreeze liberally.
- Appliances (Refrigerator, Ice Maker, Washing Machine): Clean out the refrigerator and freezer. Leave the doors slightly ajar to prevent mildew. Disconnect the water line to the ice maker and winterize it according to the manufacturer’s instructions. If you have a washing machine, follow the manufacturer’s winterization procedures, which typically involve draining and adding antifreeze.
- Batteries: Batteries are particularly vulnerable to cold weather. Disconnect them and store them in a warm, dry place. Consider using a battery tender to keep them charged during the winter.
- Tires: To prevent flat spots from forming on your tires, consider jacking up the trailer and placing it on blocks, or using tire covers.
- Seal Windows and Vents: Check all windows and vents for drafts and seal them with weather stripping or plastic sheeting.
4. Exterior Considerations
Protecting the exterior is just as important as protecting the interior.
- Roof: Inspect the roof for any leaks or damage and repair them before winter sets in. Clean the roof to remove any debris that could trap moisture.
- Awnings: Clean and retract any awnings to prevent damage from snow and ice.
- LP Gas System: Inspect your LP gas system for leaks. Consider filling your LP tanks to prevent condensation from forming inside.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions to further clarify the winterization process.
FAQ 1: How much RV antifreeze do I need?
The amount of antifreeze needed depends on the size of your trailer and the length of your plumbing lines. A good estimate is usually 2-3 gallons, but it’s always best to have extra on hand.
FAQ 2: Can I use air to blow out the water lines instead of antifreeze?
While using compressed air can help remove water, it’s not a foolproof method. Residual water can still collect in low spots and freeze. Antifreeze provides a much more reliable level of protection.
FAQ 3: Do I need to remove the water filter?
Yes, you should remove the water filter and dispose of it. Do not attempt to winterize it. Replace it with a new filter in the spring.
FAQ 4: How do I know if I’ve bypassed the water heater correctly?
After bypassing the water heater, run the water pump briefly. If you hear the pump running but no water comes out of the hot water faucets, you’ve likely bypassed it correctly. Consult your owner’s manual for specific instructions.
FAQ 5: Is it okay to leave my holding tanks (black and gray) empty all winter?
Yes, it’s generally recommended to leave your holding tanks empty and clean during the winter. A small amount of RV antifreeze can be added to each tank for added protection.
FAQ 6: What about the exterior water connections?
Disconnect and drain all exterior water connections, such as your water hose. Store the hose in a dry place. Consider using an RV antifreeze blow-out plug to force any remaining water out of the city water inlet.
FAQ 7: Should I cover my trailer during the winter?
Covering your trailer can provide additional protection from the elements, but it’s essential to use a breathable RV cover. A non-breathable cover can trap moisture and lead to mildew and mold growth.
FAQ 8: What if I want to use my trailer during the winter?
If you plan to use your trailer in freezing temperatures, you’ll need to take additional steps to prevent freezing, such as using skirting, heat tape on water lines, and space heaters. This is called “partial winterization” or “cold weather camping.”
FAQ 9: How do I de-winterize my trailer in the spring?
To de-winterize, first, drain all the antifreeze from the system. Then, flush the water lines with fresh water until the water runs clear and there’s no trace of pink antifreeze. Sanitize your fresh water tank and water lines using a bleach solution. Replace the water filter and reconnect the water heater bypass valve.
FAQ 10: Can I use household antifreeze instead of RV antifreeze?
Absolutely not! Household antifreeze is toxic and can contaminate your water system, making it unsafe to use. Only use RV antifreeze, which is specifically designed for potable water systems.
FAQ 11: How often should I check on my trailer during the winter?
It’s a good idea to check on your trailer periodically throughout the winter, especially after heavy snow or freezing rain. Look for any signs of leaks or damage and address them promptly.
FAQ 12: I have a washer/dryer combo in my trailer. How do I winterize that?
Consult your washer/dryer combo’s owner’s manual for specific winterization instructions. Generally, you’ll need to disconnect the water lines, run a small amount of RV antifreeze through the washing machine, and leave the door slightly ajar.
