Dewinterizing your trailer is the crucial process of restoring it from its cold-weather slumber, ensuring all systems are functioning correctly and ready for adventure. It involves meticulously reversing the winterization process, checking for damage, and sanitizing the water system to guarantee a safe and enjoyable travel season.
Reversing the Chill: A Step-by-Step Dewinterization Process
Dewinterizing your trailer isn’t merely about removing antifreeze; it’s about a comprehensive checkup and a revitalizing process. Follow these steps to ensure a smooth transition back to the open road.
Step 1: Inspect and Prepare
Before you begin, visually inspect the exterior of your trailer for any signs of damage – cracks, leaks, or loose components. Check the roof, windows, and seals. Clear any debris that may have accumulated during the winter.
- Check tire pressure: Inflate tires to the recommended PSI, typically found on the tire sidewall or a sticker on the trailer.
- Reconnect the battery: Clean any corrosion from the battery terminals before reconnecting. Make sure the battery is fully charged.
- Propane system check: Inspect propane lines and connections for leaks using a soapy water solution. Open the propane tank valve slowly and carefully.
Step 2: Bypass the Water Heater
Before flushing the antifreeze, bypass your water heater to prevent it from filling with antifreeze and wasting water during the flushing process. This usually involves turning valves on the water heater bypass system. Consult your owner’s manual for specific instructions.
Step 3: Flush the Antifreeze
This is a critical step. Open all faucets (both hot and cold) one at a time, including the toilet, and let the antifreeze drain. Don’t forget the outside shower, if your trailer has one. Allow the water to run until it flows clear and there’s no trace of antifreeze. Be patient; this process might take a while.
- Grey and Black Water Tanks: Ensure your grey and black water tanks are empty before flushing.
- Dispose of Antifreeze Properly: RV antifreeze is typically non-toxic, but it’s still best to dispose of it responsibly. Check your local regulations.
Step 4: Sanitize the Water System
Sanitizing the water system is essential to eliminate any bacteria or contaminants that may have accumulated during the winter.
- Prepare the Sanitizing Solution: Mix ¼ cup of household bleach for every 15 gallons of fresh water tank capacity.
- Fill the Fresh Water Tank: Pour the bleach solution into the fresh water tank. Then, fill the tank with fresh water.
- Run the Solution Through the System: Open all faucets (hot and cold) and let the water run until you smell the bleach. Close the faucets and let the solution sit in the system for at least 4 hours, preferably overnight.
- Flush the System: After the sanitizing period, drain the fresh water tank completely. Refill it with fresh water and flush the entire system again by running water through all faucets until the bleach smell is gone. This may take several refills and flushings.
Step 5: Reconnect the Water Heater
Once the sanitization process is complete and you’ve thoroughly flushed the system, reconnect the water heater by reversing the bypass valve settings.
Step 6: Inspect for Leaks
Carefully inspect all faucets, connections, and pipes for leaks. Turn on the water pump and listen for any unusual noises, which could indicate a leak. Repair any leaks immediately.
Step 7: Test Appliances
Test all appliances, including the refrigerator, stove, oven, air conditioner, furnace, and water heater, to ensure they are functioning correctly.
- Water Heater: Allow the water heater to fill completely before turning it on.
- Air Conditioner: Check the air conditioner filter and clean or replace it as needed.
Step 8: Final Touches
- Clean Interior: Thoroughly clean the interior of the trailer. Vacuum, dust, and wipe down surfaces.
- Check Smoke and Carbon Monoxide Detectors: Replace batteries in smoke and carbon monoxide detectors.
- Restock Supplies: Restock essential supplies such as toiletries, cleaning products, and first-aid items.
Frequently Asked Questions (FAQs)
Here are some common questions and answers to help you successfully dewinterize your trailer:
FAQ 1: What is the best type of antifreeze to use for winterizing?
Use RV-specific antifreeze, also known as potable antifreeze. It’s non-toxic and designed for use in drinking water systems. Never use automotive antifreeze, as it is highly toxic and dangerous.
FAQ 2: How do I know if I have leaks after dewinterizing?
Watch for dripping water under sinks, around pipes, and near connections. Listen for the water pump cycling on and off frequently, which indicates a pressure drop due to a leak. Use paper towels to check for dampness in hard-to-see areas.
FAQ 3: Can I skip the sanitizing step?
No, you should never skip sanitizing. This critical step eliminates bacteria and contaminants that may have grown in the water system over the winter, ensuring safe drinking water and preventing illness.
FAQ 4: How often should I sanitize my water system?
Sanitize your water system at least twice a year: once when dewinterizing and again after periods of non-use. If you suspect contamination, sanitize immediately.
FAQ 5: What do I do if my water heater smells bad after dewinterizing?
A smelly water heater often indicates bacterial growth. Drain the water heater, flush it thoroughly, and then sanitize it by adding a small amount of bleach to the tank, letting it sit for a few hours, and flushing again. Consider replacing the anode rod, as it can contribute to the smell.
FAQ 6: My water pump won’t prime. What could be the problem?
A common cause is air in the lines. Check all connections to ensure they are tight. Open faucets one at a time to allow air to escape. Also, inspect the pump’s filter for clogs. A cracked or damaged pump housing can also prevent priming.
FAQ 7: How do I check my propane system for leaks?
Mix a solution of soapy water (dish soap works well). Apply the solution to all propane connections and fittings. If bubbles form, you have a leak. Immediately shut off the propane and tighten the connection or consult a qualified technician.
FAQ 8: Do I need to lubricate anything during dewinterizing?
Yes, lubricate door hinges, window tracks, and slide-out mechanisms to ensure smooth operation. Use a silicone-based lubricant that won’t attract dirt and grime.
FAQ 9: What should I do with the water filter?
Replace the water filter annually or more frequently if you notice a decrease in water flow or an unpleasant taste. A clogged filter can harbor bacteria and reduce water pressure.
FAQ 10: What if I forgot where the bypass valves are for my water heater?
Consult your owner’s manual for specific instructions and diagrams of your water heater bypass system. If you can’t find the manual, search online for your trailer’s make and model.
FAQ 11: How long will it take to dewinterize my trailer?
The dewinterizing process typically takes 2-4 hours, depending on the size and complexity of your trailer. Allow extra time for thorough cleaning and appliance testing.
FAQ 12: What if I find damage during the inspection?
Address any damage immediately. Small repairs can prevent bigger problems down the road. If you’re not comfortable making the repairs yourself, consult a qualified RV technician.
