Winterizing your Jayco trailer is crucial to prevent costly damage from freezing temperatures, protecting your investment and ensuring smooth sailing when spring arrives. This comprehensive guide, backed by years of RV experience, will walk you through each essential step, empowering you to confidently prepare your Jayco for the off-season.
Why Winterizing Matters: Protecting Your Investment
Winterizing isn’t just a suggestion; it’s a necessity. The expansion of water as it freezes can wreak havoc on your trailer’s plumbing system. Burst pipes, cracked fittings, and damaged appliances can lead to significant repair bills and detract from the joy of RV ownership. Properly winterizing ensures your Jayco survives the winter unscathed, ready for your next adventure. Ignoring winterization is simply inviting expensive problems.
The Step-by-Step Winterization Process
This section outlines the core steps to winterizing your Jayco trailer. Following these instructions meticulously will provide optimal protection.
1. Draining the Water System
This is the most critical step. Any water left in the system will likely freeze and cause damage.
- Drain the fresh water tank: Locate and open the drain valve, typically found underneath the trailer near the tank. Allow all the water to drain completely.
- Drain the water heater: Turn off the water heater (both gas and electric). Let the water cool completely before removing the drain plug. Be prepared for a rush of water. Flush any sediment from the tank. Consider replacing the anode rod if it’s corroded (a highly recommended practice).
- Drain the water lines: Open all faucets, both hot and cold, including the shower and outside shower. Flush the toilet. Activate the low point drains – typically two valves located underneath the trailer near the water lines.
- Bypass the water heater: Before introducing antifreeze, bypass the water heater to avoid filling its 6-10 gallon capacity with RV antifreeze (saving you money). Most Jayco trailers have a bypass valve system near the water heater.
2. Adding RV Antifreeze
RV antifreeze is non-toxic and specifically designed for potable water systems. Never use automotive antifreeze, as it is poisonous.
- Using the Water Pump: This is the most common method. Disconnect the inlet hose from the fresh water tank and connect it to a short length of hose that can be inserted into a gallon jug of RV antifreeze. Turn on the water pump. Open each faucet, one at a time, until pink antifreeze flows freely. Don’t forget the toilet and outside shower.
- Using an Air Compressor: Connect an air compressor to the city water inlet and set the pressure to no more than 40 PSI. Open each faucet and blow out the lines until no more water comes out. Follow this by adding antifreeze using the water pump method to protect traps and fixtures.
3. Protecting Drains and Fixtures
These finishing touches ensure comprehensive protection.
- Pour antifreeze into drains: Pour a cup or two of RV antifreeze into each drain (kitchen sink, bathroom sink, shower, and toilet). This protects the P-traps from freezing.
- Toilet: Flush the toilet after adding antifreeze to the bowl to protect the valve.
- Seal openings: Cover vents and other openings to prevent pests and drafts.
4. Preparing Appliances
Properly preparing your appliances will prevent damage and ensure they are ready for use next season.
- Refrigerator: Clean out the refrigerator and freezer. Leave the doors ajar to prevent mildew.
- Stove and Oven: Clean the stove and oven.
- LP System: Turn off the LP tanks. Consider covering the regulator to protect it from the elements.
5. Battery Maintenance
Batteries can be damaged by cold temperatures.
- Disconnect the battery: Disconnect the battery cables.
- Store the battery: Store the battery in a cool, dry place that doesn’t freeze. Consider using a battery maintainer to keep the battery charged.
FAQs: Addressing Common Concerns
Here are answers to frequently asked questions about winterizing your Jayco trailer.
Q1: Can I skip winterizing if I live in a mild climate?
Even in mild climates, brief periods of freezing temperatures can cause damage. It’s always best to winterize as a precaution, especially if temperatures dip below freezing for extended periods. The cost of winterizing is far less than the potential repair bills.
Q2: How much RV antifreeze do I need?
Typically, 2-3 gallons of RV antifreeze are sufficient for most Jayco trailers. However, larger trailers with multiple bathrooms may require more. It’s always best to have a little extra on hand.
Q3: Can I use compressed air instead of RV antifreeze?
Using compressed air is a viable option for removing water from the lines. However, it’s still recommended to add antifreeze to protect the P-traps and fixtures as air alone will not prevent freezing in those areas.
Q4: Where do I find the low point drains on my Jayco trailer?
Low point drains are typically located underneath the trailer, near the water lines. They are usually two separate valves, one for hot water and one for cold water. Consult your owner’s manual for the exact location.
Q5: How do I bypass the water heater?
Most Jayco trailers have a bypass valve system near the water heater. It usually consists of three valves: one on the inlet, one on the outlet, and one that connects the inlet and outlet lines. Turn the valves so that the water flows directly from the inlet to the outlet, bypassing the water heater. Consult your owner’s manual for specific instructions.
Q6: Is it safe to leave propane tanks connected during the winter?
While it’s generally safe to leave propane tanks connected, it’s recommended to turn them off at the tank valve for added safety. Consider covering the regulator to protect it from the elements.
Q7: What should I do with the tires during the winter?
To prevent flat spots, it’s best to cover the tires to protect them from the sun and UV damage. You can also place the trailer on blocks to take some of the weight off the tires. Check the tire pressure periodically.
Q8: How do I prevent mildew and mold inside my trailer during the winter?
Ventilation is key. Leave cabinet doors and drawers slightly open to allow air to circulate. Use moisture absorbers, such as DampRid, to help control humidity.
Q9: Can I use my RV cover during the winter?
RV covers can protect your trailer from the elements, but choose a breathable cover to prevent moisture buildup. Make sure the cover fits snugly to prevent wind damage.
Q10: What if I forgot to winterize and it’s already freezing?
If you suspect your pipes have frozen, do not attempt to thaw them with an open flame. Use a hair dryer or heat tape to gently thaw the pipes. Contact a qualified RV technician for a thorough inspection. Prevention is always better than cure.
Q11: How do I winterize my washing machine (if equipped)?
Consult your washing machine owner’s manual for specific winterizing instructions. Typically, you’ll need to drain the water lines and add RV antifreeze to the drum. Run a short cycle to distribute the antifreeze throughout the system.
Q12: Where can I find my Jayco trailer owner’s manual?
Your owner’s manual is a valuable resource for information specific to your Jayco model. You can often find a digital copy on the Jayco website or through their customer service department.
Spring Awakening: De-Winterizing Your Jayco
Don’t forget the reverse process in the spring! Thoroughly flush the system with fresh water before use to remove all traces of RV antifreeze. Inspect all components for damage.
By following these steps and addressing these common questions, you can confidently winterize your Jayco trailer, ensuring it’s protected from the harsh winter elements and ready for your next adventure. Remember, proactive winterization is a small investment that yields significant peace of mind. Happy travels!
