Dewinterizing an RV: Your Complete Guide

If you winterized your RV at the end of last season, you’ll need to get it ready to use for your adventures by dewinterizing it. 

How you dewinterize your RV will greatly depend on your RV. Some RVs are easier to dewinterize than others, but the process is relatively painless.

For specific instructions, check the documentation that came with your unit. Let’s look at what you should expect to do and keep an eye on when dewinterizing an RV this season.

Freezing water can damage water lines and sensitive plumbing connections. Reference the documentation for your specific RV for dewinterizing your water system.

The Water System

When dewinterizing your RV, connect it to a water source and run water through all the faucets, toilets, and showers you previously winterized.

Drain the Antifreeze

This helps kill any bacteria growing in your water system and can ensure you can consume water from your RV.

Flush and Sanitize the Fresh Water System

Ensure you have water in your water heater before turning it on. Doing so can cause permanent damage to the heating element.
