De-winterizing an RV means flushing antifreeze from the water system, checking every seal and battery, and testing propane appliances before the first trip.
RV owners often skip straight to loading up for a trip and discover a leaking water line or dead battery only after they're already on the road.
Why This Happens
Storage systems that were shut down properly in fall need to be reactivated in a specific order, and skipping steps causes failures that only show up under use.
What's Inside
This checklist is interactive, click to check off items in your browser, plus printable if you'd rather keep a copy in the RV, and it walks through water system flushing, appliance testing, and safety checks in the correct de-winterizing order.
Quick Tips
Run water through every faucet until antifreeze smell is completely gone.
Test propane appliances outside or in a ventilated area first.
Check tire pressure and date codes before any long drive, storage flattens tires fast.

Frequently Asked Questions
How do I flush antifreeze from my RV's water system?
Run fresh water through every faucet, the toilet, and the water heater until no antifreeze taste or smell remains, then sanitize the tank.
Should I test appliances before or after the water system?
Flush and test the water system first, then move to propane appliances, since water system testing can reveal leaks that affect other systems.
Do RV batteries need special attention after storage?
Yes, check charge level and terminals, since batteries lose charge in storage even when disconnected.
How often should I de-winterize my RV?
Once a year, typically in early spring before your first planned trip, following this same system order each time.
