Successfully winterizing your Gulf Stream travel trailer is crucial to prevent costly damage from freezing temperatures, ensuring its longevity and readiness for your next adventure. This process involves draining the water system, adding antifreeze, and protecting vulnerable components from the elements.
Understanding the Importance of Winterization
As an industry veteran with over 20 years of experience in RV maintenance and repair, I’ve witnessed firsthand the devastating consequences of neglecting winterization. A burst pipe, a cracked water pump, or a frozen black tank can easily turn a dream vacation into a financial nightmare. The investment of time and minimal resources in winterizing your Gulf Stream travel trailer is a small price to pay compared to the potentially thousands of dollars in repairs you could face if water freezes within its systems. This comprehensive guide provides a step-by-step approach to properly winterizing your Gulf Stream, offering expert tips and addressing common concerns.
Step-by-Step Winterization Process
This detailed process focuses on safeguarding your Gulf Stream’s plumbing, appliances, and structure. Always consult your Gulf Stream owner’s manual for any specific model-related instructions.
Step 1: Gathering Your Supplies
Before you begin, ensure you have all the necessary supplies on hand:
- Non-toxic RV antifreeze (enough for your trailer’s plumbing system – typically 2-3 gallons)
- Water heater bypass kit (if not already installed)
- Water pump converter kit or tubing
- Wrench for removing drain plugs
- Screwdriver
- Air compressor with a blow-out adapter
- Plumbing tools (as needed for your specific fittings)
- Bucket
- Gloves
Step 2: Draining the Water System
Thoroughly draining the water system is the foundation of successful winterization.
- Drain the Fresh Water Tank: Locate the fresh water tank drain valve (usually underneath the trailer near the tank) and open it to allow all the water to drain out.
- Drain the Water Heater: Always disconnect the water heater from any power source (electricity and/or propane) before draining. Remove the drain plug (usually located at the bottom of the tank) and allow the water to drain completely. Consider flushing the tank to remove sediment buildup. If your Gulf Stream has an anode rod, inspect it for corrosion and replace it if necessary. Install a water heater bypass kit if you haven’t already. This allows you to bypass the water heater during antifreeze circulation, saving a significant amount of antifreeze.
- Drain the Water Lines: Open all faucets (hot and cold), including the shower, inside and outside. Flush the toilet several times.
- Drain the Black and Gray Water Tanks: Empty and thoroughly flush both the black and gray water tanks. A tank flush system is highly recommended for this process. Close the drain valves when finished.
Step 3: Bypassing the Water Heater
As mentioned earlier, bypassing the water heater is essential for efficient antifreeze use. This is usually achieved with a bypass valve system. If you don’t have one, now is the time to install a kit.
Step 4: Using Compressed Air to Blow Out the Water Lines
This step removes any remaining water in the lines.
- Connect an air compressor to the city water inlet using a blow-out adapter.
- Set the compressor to a low pressure (around 30-40 PSI). Never exceed 40 PSI, as higher pressure can damage the plumbing.
- Open each faucet, one at a time, allowing the air to force any remaining water out. Start with the faucet closest to the water pump and work your way outwards. Don’t forget the toilet and shower.
- Repeat the process several times to ensure all lines are clear.
Step 5: Adding RV Antifreeze
Now comes the crucial step of protecting your plumbing with RV antifreeze. Never use automotive antifreeze, as it is toxic.
- Install a water pump converter kit or tubing: This allows you to draw antifreeze directly from the jug into the water pump. If you don’t have a kit, disconnect the inlet hose from the water pump and connect a piece of tubing that will reach into the antifreeze jug.
- Turn on the water pump: Turn on the water pump and allow it to pump antifreeze through all the water lines.
- Open each faucet, one at a time: Open each faucet (hot and cold) until you see a steady stream of pink antifreeze. Repeat for the shower and toilet.
- Pour antifreeze into the P-traps: Pour a cup of antifreeze into each sink and shower drain to protect the P-traps from freezing.
- Pour antifreeze into the toilet bowl: Flush the toilet, allowing antifreeze to fill the bowl and protect the seals.
Step 6: Protecting Other Components
Beyond the plumbing, several other components require attention.
- Appliances: Refer to your appliance manuals for specific winterization instructions for your refrigerator, ice maker, and washing machine (if applicable). Some may require draining and/or antifreeze addition.
- Batteries: Disconnect the batteries and store them in a cool, dry place. Consider using a battery tender to maintain their charge.
- Exterior: Inspect the roof and seals for any cracks or damage and repair them before winter. Cover the tires to protect them from UV damage. Consider a full RV cover for added protection.
Frequently Asked Questions (FAQs)
Q1: How much antifreeze do I need to winterize my Gulf Stream travel trailer?
The amount of antifreeze needed depends on the size and complexity of your trailer’s plumbing system. A general estimate is 2-3 gallons. It’s always better to have a little extra than to run short in the middle of the process.
Q2: Can I skip the compressed air step and just use antifreeze?
While you can technically winterize using only antifreeze, using compressed air first significantly reduces the amount of antifreeze required and ensures more thorough protection. It’s highly recommended to use both methods.
Q3: What happens if I don’t winterize my travel trailer?
If you don’t winterize your travel trailer and the temperature drops below freezing, any water left in the plumbing system can freeze and expand. This can lead to burst pipes, cracked fittings, a damaged water pump, and other costly repairs.
Q4: How do I know if I’ve used enough antifreeze?
You’ll know you’ve used enough antifreeze when you see a steady stream of pink antifreeze coming out of all faucets and fixtures.
Q5: Can I use automotive antifreeze instead of RV antifreeze?
Never use automotive antifreeze in your RV’s plumbing system. Automotive antifreeze is highly toxic and can contaminate your fresh water system. Only use non-toxic RV antifreeze.
Q6: Do I need to remove the anode rod from my water heater?
If your water heater has an anode rod (common in Suburban water heaters), it’s a good practice to remove it during winterization to inspect it for corrosion. If it’s significantly corroded, replace it.
Q7: Where do I dispose of the antifreeze after de-winterizing?
RV antifreeze is non-toxic and can be safely flushed down the drain. However, always check local regulations for specific disposal guidelines.
Q8: How often should I check on my winterized travel trailer?
It’s a good idea to check on your winterized travel trailer every few weeks, especially after periods of extreme cold or heavy snow. Look for any signs of leaks, damage, or pest infestation.
Q9: What if I can’t find the fresh water tank drain valve?
Consult your Gulf Stream owner’s manual for the exact location of the fresh water tank drain valve. It’s typically located underneath the trailer near the tank. If you still can’t find it, contact a qualified RV technician.
Q10: Can I hire someone to winterize my travel trailer?
Yes, many RV dealerships and service centers offer winterization services. This is a good option if you’re not comfortable doing it yourself or if you lack the necessary tools and equipment.
Q11: What should I do with my RV cover in the spring?
Clean and dry your RV cover thoroughly before storing it for the summer. This will prevent mold and mildew from forming. Store it in a cool, dry place away from direct sunlight.
Q12: How do I de-winterize my Gulf Stream travel trailer in the spring?
De-winterizing involves flushing the antifreeze out of the water system and reconnecting all the components. Follow a similar process in reverse, ensuring you thoroughly flush the system with fresh water before using it. Replace the water heater drain plug and sanitize the fresh water tank.
By following these steps and addressing these common questions, you can confidently winterize your Gulf Stream travel trailer and protect it from the damaging effects of freezing temperatures, ensuring it’s ready for your next adventure when spring arrives.
