How to Winterize Your RV Using Compressed Air: A Bama RV Guide
Winter is upon us, and for RV owners, that means it's time to prepare your camper for storage during the colder months. At Bama RV, we know the importance of protecting your investment, so we’ve crafted this easy-to-follow guide on winterizing your RV using compressed air. This method is efficient, reduces the need for antifreeze in your lines, and makes de-winterizing a breeze when spring arrives.
What You’ll Need:
Air compressor (with attachments)
1 gallon of RV antifreeze
1 1/16” socket and ratchet (to remove the water heater anode rod)
Plastic city water adapter with nipple
4 feet of 1/4-inch plastic tubing
Step-by-Step Instructions:
1. Drain the Fresh Water Tank
Locate the fresh water tank drain line (usually on the RV’s underbelly) and remove the cap. Allow the tank to empty completely.
2. Drain the Water Heater
Remove the water heater anode rod using the 1 1/16” socket and ratchet, draining the tank completely. Close the bypass valve on the water heater’s input line to prevent antifreeze from entering the tank.
3. Empty Hot and Cold Water Lines
Remove the caps from both the hot and cold water drain lines (found underneath the RV). Inside the RV, turn on the auxiliary water pump to clear any remaining water. Once drained, replace the cold water cap and leave the hot water line open for now.
4. Set Up the Air Compressor
Power up your air compressor. Attach the city water adapter to your RV’s city water connection. Connect the 1/4-inch tubing to the adapter’s nipple and the compressor’s blow gun.
5. Blow Out the Water Lines
Blow air through the system to clear water from the lines. Start with the hot water line—once clear, cap it off. Repeat the process for the cold water line, ensuring all water is expelled before capping it off.
6. Clear Interior Lines
Starting with the bathroom, have a friend press down the toilet lever while you blow air into the system. Ensure all water is cleared. Repeat this process with every water fixture in the RV, including sinks, showers, and outdoor water utilities. Note: Do not apply air pressure with all lines closed to avoid damaging the system.
7. Siphon Remaining Water from the Water Heater
Use a 2-foot section of 1/4-inch tubing to siphon any remaining water from the water heater. Inspect the anode rod for wear and replace it if necessary. Reinstall the anode rod and reopen the bypass valve on the water heater input line.
8. Add Antifreeze to P-Traps
Pour RV antifreeze into all P-traps, including sink drains and the shower. Use about 1/3 gallon per trap to ensure they are adequately protected.
