The Beginner's Guide to RV Winterization: 5 Mistakes to Avoid

Welcome to the RV lifestyle! Owning a rig brings incredible freedom, but it also brings new responsibilities—and nothing tests a beginner quite like their first winter. "Winterizing" is the process of preparing your plumbing to survive freezing temperatures, and doing it incorrectly can lead to severe structural issues.

Essential Winterization Checklist

Before the first freeze hits your campground, make sure you cover the essentials:
• Drain the Tanks: Empty your fresh, gray, and black water tanks completely.
• Clear the Low-Point Drains: Open the lowest valves in your rig to let residual water escape.
• Bypass the Water Heater: Ensure you don't accidentally fill your heater tank with antifreeze.
• Automate the Exterior Connection: Protect the connection between the campground spigot and your rig.

The Most Common Rookie Mistake

Many beginners focus entirely on the inside of the RV while leaving the exterior water connection completely vulnerable. When the campground spigot freezes, it backs up pressure into your rig's internal inlet, causing cracks hidden deep behind your interior panels. Installing an automatic freeze valve at the spigot solves this issue entirely.
